Cos'è l'audio ad alta risoluzione? Come funziona? Perché è necessaria l'alta risoluzione?
Di seguito troverai una spiegazione dettagliata di cosa sia l'audio ad alta risoluzione. Se vuoi leggere una spiegazione rapida, leggi questo articolo sull'audio HD...
L'essenza della musica ad alta risoluzione:
- L'audio ad alta risoluzione (audio ad alta risoluzione, audio ad alta definizione) è una famiglia di formati di musica digitale con risoluzioni superiori a 16 bit/44,1 o 48 kHz. Il DSD (Direct Stream Digital) a 1 bit è incluso nell'audio ad alta risoluzione.
- La musica ad alta risoluzione ha lo scopo di offrire un'esperienza di ascolto migliore rispetto all'audio dei CD standard, grazie alla qualità del suono più elevata.
- L'audio ad alta risoluzione è uno dei termini diffusi tra audiofili, fornitori di prodotti hi-fi e professionisti della produzione musicale.
Per una migliore comprensione dell’alta risoluzione, consideriamo un dipinto.
- La registrazione analogica è come dipingere con tratti grossolani. È bellissimo e ha una sua natura artistica.
Tuttavia, ai nostri occhi non è troppo vicino all'immagine originale.
- La qualità audio del CD è simile a quella di una foto a colori scattata con una vecchia macchina fotografica. C'è qualche sfocatura. Non possiamo vedere tutti i dettagli sottili. Tuttavia, è più simile all'oggetto originale.
- L'alta risoluzione è come scattare foto con una moderna fotocamera digitale e stamparla con qualità professionale. Possiamo vedere tutti i dettagli dell'immagine originale. Non c'è alcuna sfocatura.
Se queste moderne fotocamere e stampanti non vanno bene, il risultato potrebbe essere peggiore rispetto alle vecchie apparecchiature, che abbiamo confrontato con i CD sopra.
L'audio ad alta risoluzione suona davvero meglio del CD? Non esiste una risposta semplice alla domanda. Continua a leggere per conoscere i dettagli.

Nell'immagine possiamo vedere una visualizzazione artistica approssimativa delle differenze di formato audio. Non è una vera distinzione. È importante come sono fatti questi sistemi musicali. Tuttavia possiamo osservare delle tendenze generali.
Ad esempio, i sistemi analogici corrompono il suono:
- "Wow and flutter" è un tono fluttuante dovuto alle fluttuazioni nella velocità di rotazione del nastro o della registrazione in vinile.
- La "compressione del nastro" è una distorsione non lineare vicina al livello di sovraccarico del segnale di ingresso. Riduce dolcemente il livello di uscita quando il livello di ingresso viene aumentato linearmente.
Alcune colorazioni possono causare un "aspetto" più "carino" o "interessante" per i mezzi analogici, se confrontati con le fonti digitali. Nonostante questi ultimi siano oggettivamente più vicini alla fonte acustica originale.
Quando la registrazione in vinile viene prodotta da un nastro in studio, le loro distorsioni vengono fuse in modo complicato.
L'alta risoluzione non presenta questi problemi "analogici". Tuttavia, le registrazioni digitali potrebbero avere degli alias. Vengono visualizzati come copie spostate del segnale originale; nella foto: immagini semitrasparenti spostate.

Hi-res audio was designed to provide higher sound quality and a better listener experience, than standard CD audio. Read below: is the aim achieved or not?
PCM 44.1 kHz / 16 bit vs. High resolution: PCM and DSD
According to current theory and practice, human hears up to 20 kHz. At first sight, CD resolution fully covers the frequency range and hi-res doesn't need.
However, high-resolution audio may solve some distortion issues in the audible range. I.e. high-res solves equipment issues.
The author wants to remind, high-resolution doesn't guarantee improvements. It gives abilities only. Bad-made HD system can sound worse than a good-made 44.1 / 16 one.
Below read details about whether can humans hear hi-res audio or not.
Below we'll consider how a bit depth increasing affects sound quality.
In theory, 24-bit has lower distortions than 16-bit resolution.
Practically, there are many factors, that may waste the advantages of the higher resolution.
For instance, a picture is assembled from 100x100 squares and has a size like a home window.
This picture is well visible from 10 steps. The image looks smooth.
We want to increase the distance range (loudness range). I.e., we want to see the picture from both 10 and 100 steps.
So, we should increase the picture size to the size of the home wall.
After it, the square sizes become larger.
But, we want to keep a good look at the smaller 10-step distance too.
And we should use smaller squares in greater numbers: 300 x 300, in instance.
So, to see from 10 steps and 100 ones (both quiet and loud sounds), we need a higher 300x300 resolution instead initial 100x100 one.
Some kinds of music with a wide loudness range (like classical, jazz, soundtracks), demand a wider dynamic range of a music system.
The range may be achieved through resolution increasing. It allows the keeping of distortion levels at various loudness.
Also, genres may vary in a frequency range. But, according to the current common sound theory, the audible range does matter in any case. And, high-res doesn't add something to it. It is worth remembering, that a high sampling rate allows for solving some distortion issues in the audible range.
If we have the hi-res now, we can also ask: what is the highest quality music? In hi-fi, we look for minimum distortions. Higher sampling rates and bit depths give potential abilities to achieve better sound quality. It means lesser distortions. Nevertheless, the actual result depends on implementation of audio equipment and software.
For understanding how implementation impacts audio quality, let's consider the example:
We can design several different binoculars that allow seeing at 7 miles.
But glass transparency for each binocular model makes its individual image quality.
The same things are in the audio. Even if we discard ultrasound, audio format with higher resolution should provide better sound in the audible range primarily.
In the moment of the answer writing, some DACs provide:
- sampling rates are DSD 1024 (45.16 MHz), PCM 1536 kHz;
- bit depth is 32-bit.
It is necessary to remember, that an actual DAC noise floor is limited by electronic hum (approximately -120 dB). However, when using 32-bit formats, engineers do not particularly worry about digital processing into a digital-to-analog converter. On the other hand, there are other factors, that can increase or reduce audio quality.
The noise floor may be considered as a water level in a pool.
An audio signal is like a ball. The upper ball part may be visible the same way when moving from one poolside to another one. It's like the same signal level at any frequency from zero to the highest one.
The different signal levels are different altitudes above the water level.
Like a denser thing falling deeper under the water. In instance, wood floats, but an iron block sinks.
In the same way, the ball may move underwater.
The water in the pool is opaque. And we can't see the ball under the water.
In other words, the signal under the noise floor is like the ball under the water level in this pool.
Lossless audio formats (FLAC, WAV, ALAC, AIFF, DSF) are recommended. However, lossy audio formats (AAC, mp3, etc.) with high bitrates (kbps) may save hard disk space. And their sounding may be indistinguishable from lossless original files.
- DAC advantages/disadvantages...
- NOS DAC advantages/disadvantages...
- Power conditioning, it's real or not...
We haven't full control of a recording level. As example, in classical music recordings. Digital recording demands some tricks to avoid analog and analog-to-digital conversion overload distortions, that can not be fixed after the record.
Overload is the limitation of output level growth when input level of a device or software continues to increase.
Let's look at an example:
We have an empty pot (audio unit: device or software).
And we are beginning to pour water into the pot (the input level is growing).
The level of the water (output level) is growing. It becomes higher and higher.
When the level achieves the highness of the pot (maximum signal level for the unit), water overflows.
And, after it, the pot's water level is constant despite how much water will be poured (input level growing).
If we take the pot (audio unit) with higher walls, overflow is coming after more input water volume (higher input level).
However, reducing the analog signal level at analog-to-digital converter (ADC) input can cause a worse signal-to-noise ratio. Especially, for low-level fragments of a music piece.
So, ADC should have a wider dynamic range, to reduce the risk of damaging the recorded signal.
The inherent noise of a digital signal is called quantization noise. It rises due to the error in measurement of the analog signal that is digitized.
Analog-to-digital converter (ADC) has electrical circuits that produce electrical noise.
In general, the quantization noise should be lower, than ADC's electrical noise.
ADC's maximum level is 0 dB and the noise floor is -120 dB.
We record a symphony orchestra with 2 microphones.
To avoid overload, we reduce the input analog level of ADC. It gives some loudness reserve. But it degrades the signal-to-noise ratio of quiet musical fragments.
A lesser reserve is more the signal degradation. It happens due to a lower signal-to-noise ratio. The ratio defines waveform purity.
Lower bit depth
If we use a lower bit depth resolution, it can cause quantization noise, that may be higher than the electrical noise floor of the ADC.
In instance, 16 bits cause a quantization noise floor of about -100...110 dB. It's above -120 dB of electrical noise.
And such signal-to-noise ratio falls and audio quality gets more degradation.
Digital signal processing (DSP) is any kind of manipulations with digital signal: gain control, equalizer, etc.
Resolution of further digital signal processing may be increased, to "transparent" work with sound for DSP designers.
Read more details in "Does 24-bit sound better than 16-bit?" part below.
There are many questions about the necessity of hi-resolution music recordings.
One people thinks, that "excessive" resolution wastes disk space only.
Other people think, that such records are needed to produce ultrasound.
But, in the author's opinion, high-res may be useful due to other reasons. Read "Myths" part below.
Opinion, that high res gives advantages always, is not correct for all cases.
Sometimes people, who play records with high sample rates, stumble with unexpected noise or other unwanted sounds.
In "Myths" part below you can watch the video with example.
Hi resolution may be played back at:
- portable audio players,
- mobile phones [smartphones],
- tablet computers,
- music servers,
- SACD and Blu-Ray players,
Separate [DAC-headphone amplifier] device may be used to connect to a mobile phone, portable player, computer and etc.
There are high res music players Mac, Windows [PC], iPhone, Android.
Mobile phones on Android and iOS (smartphones) can play hi-res audio. You can install audio player software and listen to music.
Some phones have pre-installed audio player software/functionality.
Audiophile and professional audio conversion software should provide a wide range of sample rates and bit depth, including 32-/64-bit.
High-resolution audio solves issues of non-linear distortions primarily. However, it is one dimension of sound naturalness.
The second dimension is a spatial distribution of acoustic waves in the listening point. Read details...
Let's suggest the average song is 3 minutes.
Approximate size of 1000 songs (stereo audio files)
KBit per second*
* 1 KBit/s = 1000 bit/s of compressed stream
** GByte = 1024 * 1024 * 1024 bytes, average FLAC compression is suggested at 60%.
24 bit suona meglio di 16 bit?
In itself, 24 bits does not sound better than 16 bits. It's only one of many factors. But it gives potential technical abilities to improve sound quality.
Bit depth in simple words
We can imagine music as a puzzle picture.
Bit depth is like the size of the puzzle element.
Higher bit depth it's like smaller elements.
Read more about bit depth...
When bit depth is discussed, the human hearing range (about 130 dB from inaudible to pain) is taken as the reference value.
16-bit resolution has a difference of about 96 ... 110 dB between the lowest (noise floor) and highest peak levels.
It looks like enough to cover almost the full 130 dB range.
However, the range doesn't consider sound quality aspects.
A low hearing threshold is 0 dB. It's a quiet rustle of leaves, as an example. Such sound has its own signal/noise ratio too.
As an example, we want to provide proper sound quality (like tape's 60 dB) at 0 dB audible level.
So we can add about 60 dB to 130 dB (total of about 180 dB) to provide allowable quality at the lowest levels.
It is not exact numbers, because the author doesn't have a result of researches. But we can get it as the hypothesis.
So sample depths, higher, than 16 bit, may be needed.
Direct Stream Digital solves the dynamic range issue via noise shaping.
Let's low levels of a music piece have a bad (low) signal/noise ratio.
We want to improve the listening experience of these piece places. And we boost volume control.
And we begin to listen to these places better way. But noise is boosted together with music. And it degrades the sound.
To reduce the noise in quiet places of the piece, we should reduce noise level there. If bit depth is bottle-neck, we can do nothing.
But bit depth reserve gives us the ability to boost of record level:
- without noise level increasing (if DAC is noise bottle-neck); or
- signal noise of the quiet places is good enough even for higher loudness.

Perché è necessaria una frequenza di campionamento superiore a 44,1 kHz
Sample rate 44100 Hz:
- cover audible band 0 ... 20 000 Hz and
- have 2050 Hz reserve for the transient band of low-frequency filter (in ADC and DAC).
However, the reserve is abstractly considered. Real-life filters are analog. They have a wide transient band.
To solve the wide transient band issue, digital filters, higher sample rates, oversampling are used.
But digital filters are not ideal and have:
- ringing audio (property of digital filters);
- limitation of the minimal size of the transient band (due to limited computing resources for example).
To reduce "hard" efforts to achieve a proper filter transient band, higher sample rates (including DSD) may be used.
Read details issues of sample rate and filters:
Back to top
High res is not intended for record and playback of ultrasound.
Analog filters are not steep and can't suppress aliases properly in allowable band 20 000...22 050 Hz for 44 100 Hz sample rate.
Higher sample rates allow placing aliases at higher frequencies, in a better suppression range of the analog filter.
The issue may be partially solved via:
- digital filtering and decimation in ADC or
- oversampling and digital filtering in DAC.
However, an issue with the quality of filtering may be there due to limited computing resources of hardware.
Resume: high resolution is intended for analog filters in ADC and DAC. And ultrasound playback is a consequence of higher sample rates. Ultrasound playback is not the target of hi-res records.
Practical experience, which may be checked right at home, says, that we can't hear sines with frequencies above 16 ... 22 kHz. And there are no surprises for multiple trials.
There is a study:
- Toshiyuki Nishiguchi, Kimio Hamasaki, Masakazu Iwaki and Akio Ando: Perceptual Discrimination between Musical Sounds with and without Very High Frequency Components
This study didn't find a significant difference between samples with and without very high-frequency components. However, the authors of the research neither confirm nor deny a general human possibility to discriminate music with and without the components.
Another hand, some researches, that studied ultrasound issues:
- Milind N. Kunchur, 2007: Temporal resolution of hearing probed by bandwidth restriction
- Lisa Zyga, 2013: Human hearing beats the Fourier uncertainty principle
- Tsutomu Oohashi, Emi Nishina, Manabu Honda, Yoshiharu Yonekura, Yoshitaka Fuwamoto, Norie Kawai, Tadao Maekawa, Satoshi Nakamura, Hidenao Fukuyama and Hiroshi Shibasaki, 2000: Inaudible High-Frequency Sounds Affect Brain Activity: Hypersonic Effect
Some of the studies show, that we may have a brain response to ultrasound. But, it is unknown, how ultrasound impact to sound quality.
For high resolutions, the interpolator (analog low-frequency filter) is easier to implement in better quality (see myth #1).
For the comparison, we must have pure samples, that are cleared of other factors.
As rule, such comparison is seen as a blind test of samples provided by a label in different resolution. As an example, one album is distributed in 24-bit/192 000 Hz and 16 /44 100.
However, the main issue is there, that it is impossible to record "clean samples".
As an example, we split a signal from microphone to 2 audio interfaces, that work in different resolutions. But we can't split into two completely identical signals. The identity of two interfaces is a more sophisticated task than splitting.
When a single sample (music album) is converted to test with software, we don't know whether we compare: converters or resolution.
But, even, when converted samples are played back at single DAC, it may work in different modes (electrical circuit, digital processing) for various resolutions.
The author would suggest considering all known kinds of tests like "hi-res vs 44/16" as a comparison of hardware and/or software, not as comparisons of music signal resolutions.
Test standard vs high-resolution:
Sound quality depends on many variables:
- mixing/post-production software and hardware tools,
- skills in recording/mixing/post-production engineer,
- recording and playback environment,
- quality of resolution conversion;
Format/resolution is one of them only. No warranties, that DSD1024 will sound better than standard PCM 44/16.
No. High-resolution formats contain ultrasound. Theoretically, it does not matter for ears, because we don't hear frequencies above 20 kHz.
But, practically, music hardware and, sometimes, software have non-linear distortions. It can cause audible products from inaudible high-frequency components (intermodulation distortions).
In the educational video below, noise removal via ultrasound filtering is shown.
Read more about optimization of audio >
In general case, higher sample rates and bit depth guarantee nothing. The result depends on implementation quality.
A professional audio interface at 44100 Hz can give better sound, than a built-in sound card at 192000 kHz.
If consider altering of resolution (resampling) as itself, it is lossy processing always.
After upsampling no information is added. Conversely, we have losses, as we told above.
But we can't consider a recording without considering of playback music system.
And the system may have different distortions for various modes (combinations of sample rates and bit depths).
So, we can optimize the recording to better playback mode: choose the mode with minimal distortions.
To reduce conversion losses, audio conversion algorithm should have minimal distortions.
However, it needs to remember, that the sampling rate increase doesn't give advantages on its own.
Theoretically, in some cases, reducing a sample rate may make sound better.
In other cases, no audible difference between resolutions.
Each case should be learned individually.

Audio PCM ad alta risoluzione
High-resolution PCM is supported by lossless files: WAV, AIFF, FLAC (up to 384 kHz / 32 bit), WV (WavPack), DVD, Blu-Ray, etc.
32/64-bit float formats are intended for music production and scientific purposes rather.
Also, new digital-to-analog converters support sampling rates up to 1411/1536 kHz. High rate values are especially recommended for non-oversampling DACs.

DSD (Direct Stream Digital) is a 1-bit audio format with a very high sample rate (from 2.8 MHz). This signal is based on sigma-delta modulation.
To reduce the noise level and expand the dynamic range, noise shaping is used there.
Mediums: DSF/DFF/SACD ISO files, SACD optical disk.
Back to top
DXD (Digital eXtreme Definition) is a PCM format with a high sample rate, derived from Direct Stream Digital.
DXD contains a low part of Direct Stream Digital's spectrum with DSD noise "hump".
Only low part of the DXD spectrum contains useful musical signal.
Noise level is growing to higher frequencies.
As rule, Digital eXtreme Definition has sample rates 352 800 Hz and above and 24-bit and above resolution.
Primarily, DXD format is intended to edit DSD.
However, there are PCM lossless formats that may be used like DXD.
Read DSD editing details...
However, not all PCM files with such sample rates are DXD. Traditional Pulse Code Modulation has no significant noise level at high frequencies.
Playback devices can filter high-frequency noise to save dynamic range and avoid intermodulation distortions.

Compressione dei dati audio per audiofili
MQA is intended for audio data compression of high-res PCM.
As rule, it has a compression ratio better than FLAC.
But, as the author knows, MQA is not lossless for all resolutions. Because the "classical" definition of the "lossless" term means "no binary information losses after compression and restoration of an audio file". Read details here.

PCM, DSD, DXD, qualità del suono analogico
In the first approach, DSD, DXD, PCM formats give the same opportunities to designers of a music system.
A music system may be done differently according to the real vendor's abilities.
PCM has no technological "hump" of noise at high frequencies. Direct Stream Digital and Digital eXtreme Definition have the "hump".
So, for PCM, it's not necessary to suppress the high-frequency noise.
On the other hand, we don't hear ultrasound (see details below in "Myths"). And this noise is not audible.
Nevertheless, music system hardware and, sometimes, software have non-linear distortions.
The distortions can cause the generation of audible products (noise, as rule) by inaudible high-frequency noise. It's called intermodulation distortions. See more here >
So, if you hear noise in hi-res audio playback, read what can be done...

Hi-res music is music that is produced and stored in hi-resolution formats. They provide a sample rate over 48 kHz and bit depth is 24-bit and higher or 1-bit Direct Stream Digital).
No. Hi-res audio solves 44.1 kHz /16-bit issues. However, a high sampling rate and bit depth doesn't guarantee higher quality. It gives just potential possibilities.
High-res audio recordings can "open" better sound quality of your audio system, if it is capable of 24-bit/88 kHz resolution and above. However, there are no warranties, that hi-res bring better sound.
Hi-res audio doesn't correspond to lossless or lossy directly. Both these formats may contain sampling rates above 48 kHz and bit resolutions above 16 bit. However, lossy mp3 doesn't support high resolution audio technically.
There is no limit to sound quality. As rule, the quality is estimated by distortion level. Modern digital systems are close to the limit of improvement by distortions.
Digital systems are moved far ahead in this matter. However, there is the next step of enhancement.
Sound quality has 2 definitions:
- distortion level;
- subjective estimation of sound "beauty".
Distortion level estimates the degrading of sound of an original. But not only integrated level of distortions does matter. The character of the distortions makes an audio quality that is subjectively perceived. This phenomenon is studied by psychoacoustics.
Subjective estimation can prefer more distorted audio as "better sounding". Because some kinds of distortions can bring "warmth", "coziness", etc. of sound.
Resume: The best sound is zero distortions. But some distortions can "enhance" sound "beauty" ("colorization"). Analog sound is more colorized and it may be considered more pleasant.
Lossy formats (mp3, AAC, etc.) allow for saving more space on a hard disk. But, some audio information losses are there. However, high-bitrate (256 kbps and more) formats have a sounding that is very close to lossless ones.
Audio quality of both recording and playback units is essential.
The best audio quality is provided by lossless audio formats.
You can read about hi-res certification.
It depends on quality of upsampling and your playback audio system. In general case, a higher sample rate has a better potential for lower distortions in a DAC.
You can't restore mp3 coding losses. However, you can maximally keep what's left if uses hi-fi equipment.
Hi-res audio gives abilities to get more "transparent" sound. It happens due to higher sample rate and bit depth allopws to achieve lesser distortions. You can try this way to check it...
However, an equipment has non-linear distortions. And, some audio units may cause audible noise for certain high-resolution recordings.
For certain equipment and recordings, difference between hi-res and CD may be audible. But, there is no technically correct way of comparison.
High-resolution audio potentially allows for reducing distortions of recording and playback. But actual result depends on audio unit/system implementation.
Theoretically, high-res causes lesser distortions than CD-audio. Practically, we should consider given audio units, software and recordings.
It is not fairly for every case. Hi-res audio has potential abilities to achieve lesser distortions. And a lot of cases show that high resolution sounds better than 44.1 kHz / 16 bit.
Also, it's necessary to remember, that listening comparison between CD and high-res audio is not technically correct.
Highest quality music formats are lossless formats, that are capable save original digital data without losses.
Question "what is better DSD or PCM" has no single answer. It depends on implementation of equipment and played recording.
From point of view of format-resolution-abilities expanding, WAV and AIFF give great abilities due to flexible file structure.
Lossless audio formats, like WAV, FLAC, DSF, DFF, SACD, provide the best sound quality among hi-res audio formats. To achieve lesser space on hard disk or transmit music via a network, you can use audiophile lossy format like MQA. Also, other modern lossy formats, like AAC, give hi-fi quality at high bitrates.
Lossless sound formats (WAV, FLAC, AIFF, ALAC, DSF, DFF, others) provide storing of audio stuff without losses.
So, these formats can be considered as the best by the sound quality.
Read more details...
To achieve highest sound quality, digital lossless audio formats are recommended: FLAC, WAV, ALAC, AIFF, DSF, DFF, etc.
Highest quality music format is one of lossless codecs: FLAC, WAV, AIFF, ALAC, WavPack, DSF, DFF, SACD ISO, and others.
Audio format can't improve the sound quality. But the format can keep the quality and bring proper resolution, which allows an audio equipment use better way. Lossless formats (WAV, FLAC, DSF, etc.) are the best decision to achieve these aims.
To get highest quality you can consider WAV, FLAC and DSD audio formats. Also, you can use high-quality lossy format, in instance, MQA.
Lossless music formats give the best sound quality.
Audiophiles uses different audio formats. Most popular: FLAC, WAV, AIFF, DSF, MQA.
Here you can read how to choose the best audio format for you...
LP (vinyl) is mechanical system with its own distortions. These distortions are bigger than CD's ones.
But these distortions may sounds richer than without them. And some people prefer analog sound.
WAV is a lossless format, that fully keeps audio quality of a recording. mp3 saves free space of a data storage, but lose some sound information.
However, high bit rate mp3 is almost indistinguishable from its source WAV.
A general recommendation is to use WAV. If hard disk storage is not enough, use mp3 with bitrate higher as far as possible.
Lossless audio is the best audiophile choice. Lossy formats may be recommended to save space on hard disk. It is actually for mobile devices.
Theoretically, lossless audio is the best format by technical reasons. Because, it doesn't cause distortions.
However, you may don't get audible difference between lossless and qualitative lossy formats.
CD quality is 44.1 kHz (41000 Hz) / 16 bit.
There are no abstract high-res and CD (44.1/16). We can oly compare given recording on given music system.
Sound quality of 16 bit FLAC is the same CD for 44.1 kHz sampling rate.
CD quality is 44 100 Hz sample rate and 16 bit.
16 and 24 bit is only potential abilities for audio device designers. Actual result is formed from applied decissions, that absed on the abilities. More abilities don't guarantee result.
In contrast to 16 bit, 24 bit audio has noise floor reserve for moderm DAC.
24 bit get potential abilites for better sound.
Read more details...
24-bit gives technical advantages to better sound quality. But it's not that simple.
32 bit audio may be closer studio original (32-bit float, as example). Such resolution is the good for manipulation with audio, especially 32- and 64-bit float. For a DAC float point should be converted to integer value.
24-bit has precision reserve for electrical noise and required dynamic range. So we have options: 24- or 32-bit integer format for DAC playback.
In the general case, we should not expect a better quality of 32-bit than 24-bit.
As rule, 24 and 32 bit's quantization noise is placed below electrical noise floor of ADC and DAC.
32 bit has great noise floor reserve comparing 24 bit.
It's recommended to use 32-bit files for music production and other audio file processing.
Actual sound quality of playback for 24- and 32-bit files may depend on DAC device and music player implementation.
48 kHz gives some technical advantages comparing 44.1 kHz. But, there are many factors, impacting audio quality, in addition.
192 kHz gives some technical advantages comparing 96 kHz.
192 kHz / 24 bit give potential advantages comparing CD format.
24 bit / 192 kHz gives technical abilities to improve sound quality, comparing 44.1 kHz / 16 bit.
However, recording, device and software implementation does matter.
Technically, 192 kHz sampling rate allows building analog filter of DAC better than 44.1 kHz.
It may reduce distortions and improve dynamic range.
In first approach, bitrate (estimated in kbps, kBit per second) means how many information file contains about second.
Lossy files are size compressed source files. For lossy files, higher bitrate allows keeping more information about source stuff.
Of cource, losses-per-bitrate decreasing depending on algorithm of the size compression.
Also, own recording quality is primary key of audio quality for any bitrate.
Different lossless formats and their settings have various bitrates. In instance, FLAC may have about 600...800 kbps for stereo 44.1 kHz / 16 bit.
CD quality bitrate is 1411 kbps ≈ 44100 kHz * 16 bit * 2 channels / 1024.
CD-audio bitrate is about: 1411 kbps ≈ 44100 kHz * 16 bit * 2 channels / 1024.
As rule, high quality audio uses 250 and more kbps.
There is no such term by technical reasons.
- DSD1024 stereo has 90316,8 kbps.
- AptX HD codec has up to 576 kbps.
- AAC and mp3 has 320 kbps for high-quality stereo applications.
Read more about audio formats...
128 kbps bitrate of audio file may be used for music. But higher bitrates (256 kbps and more) are recommended.
As rule, 256 kbps is more recommended for high quality music.
256 kbps is better than 128 kbps by sound quality. Read more...
320 kbs is not CD quality. Such bitrate is property of lossy codecs. As rule, CD quality has bitrates above 600 kbps (in FLAC compressed stream). Uncompressed CD quality is 1411 kbps.
320 kbps is not hi-res. It is term referring data compression.
Sampling rate and bit depth define hi-res or not.
If you are need significantly keep space at hard disk of your device and high sound quality, 320 kbps is proper bitrate.
320 Kbps bitrate of mp3 format is estimated close to CD quality. Some listeners can't distinguish these formats.

FLAC supports sample rate up to 384 kHz and bit depth up to 32 bit.
Yes. FLAC is capable to store high quality music.
Yes. FLAC supports 24 bit. Read more...
24-bit FLAC provides better potential sound-quality abilities than 16-bit one.
The standard program library of Free Losless Audio Codec may do not support FLAC 32 bit.
However, FLAC is 32 bit capable.
Yes. FLAC is lossless PCM audio format, that provides the binary identity of original and uncompressed information.
Read more details >
Yes. FLAC support uncompressed audio content.
FLAC is designed for lossless size compression of sound files. So, maximal compression ratio (minimum file size) is main criterion. Because sound quality doesn't depend on the level. It is level 9.
However, higher compression level consumes more time without dramatical improvement of compression ratio. And, if it's critical, compression level may be reduced.
There is opinion, that real-time FLAC uncompression causes additional distortions. But there is no safe evidences. And uncompressed FLAC is preferable.
It is a technical limitation for lossless formats (original and uncompressed audio are binary identical).
We can approximatelly estimate FLAC size compression ratio about of 60%.
Uncompressed audio is 2 ch x 16 bit x 44100 Hz = 176 KBytes per second.
Thus, compressed FLAC is 176 KBytes/s * 60% = 106 KBytes per second.
Maximum sound quality (resolution audio) of FLAC is 32 bit / 384 kHz.
FLAC is a high-resolution format for audiophile music. Its' main advantages are:
- lossless ability (size-compressed and uncompressed audio data are binary identical);
- wide metadata compatibility with many playback software and hardware.
However, it you need support of a hi-res above 32 bit, or float-point formats, or sampling rate above 384 kHz, WAV RF64 may solve the issue.
Technically, FLAC has limitations in resolution audio. However, the resolution gives potential-only design abilities to reduce distortions. And using of super-high sampling rates and bit depths is no guaranteed way to achieve sound quality. Audio-item design is the main matter.
Also, DSD format allows solving some issues of PCM analog-to-digital and digital-to-analog conversion.
FLAC is one of the lossless formats, like WAV, AIFF, APE, DSF, SACD, etc.
FLAC has sample rate and bit depth limitations: 32 bit / 384 kHz. WAV and AIFF are more flexible.
But FLAC has wide support (including metadata) of software and hardware and lossless size compression.
FLAC sounds good as it may be possible. However, Free Lossless Audio Codec is limited by sampling rate and bit-depth. Other lossless formats .wav, .dsf, .dff may bring abilities to achieve higher sound quality.
FLAC give more abilities to achieve lower distortion level. Read more...
Technically, Free Lossless Audio Codec allows achieving better signal/noise ratio, than a CD.
But actual sound quality depends on the implementation of audio playback system and recordings.
No. FLAC sounds the same WAV, if playback is correct. There is opinion, that WAV is sounding better. But no safe evidence are there. Read more...
FLAC is lossless format like WAV. They are same for audio quality. FLAC provides better compatibility with software and hardware for metadata, file size (more 2 ... 4 GB). However, WAV provides sampling rates up to 2^32 Hz with 1 Hz step.
FLAC may contain high resolution audio...
FLAC is a lossless codec up to 384 kHz 32 bit. mp3 is lossy 44.1/48 kHz 16 bit. So, FLAC is better than mp3 by sound quality anyway.
However, mp3 in 320 Kbps gives significant size compression comparing FLAC with negligible quality losses.
MP3's sound quality is defined by bitrate. At high bitrates (above 200 kbps), audible sound quality is very close lossless formats.
However, if listen to better sound for FLAC, use it. Except cases, where song number at a file storage is critical and FLAC can't satisfy you.
FLAC is lossless formats. mp3 is lossy. So, technically, FLAC is better mp3 in any bitrate.
But the difference between FLAC and mp3 320 Kbps is very subtle, that may be inaudible.
Read more details...
Lossless audio formats like FLAC are technically better than lossy ones independently bitrate.
However, high bitrates 320 kbps and others are very close lossless quality.
For sound quality, FLAC or ALAC is not mattered. But compatibility with audio player issues may be there.
FLAC, as a lossless codec, keeps and restores the full quality of music stuff. However, FLAC has limitations by sampling rate (384 kHz) and bit depth (up to 32 bit, integer only). For end-user distribution, it may be considered as enough.
But, sampling rate and bit depth of an audio file doesn't define sound quality separately without recording and playback equipment.
And a higher sampling rate may bring sound quality advantages potentially. For instance, WAV format has sample-rate limitation up to 232 Hz. However, ordinary WAV is limited by length (232 bytes). The issue is solved via WAV RF64 format.
RF64 has narrower compatibility with software and hardware comparing FLAC, which also is capable with audio-stuff size of more 232 bytes.

Lack of spectrum content above 16 kHz may be caused mp3 compression of source of a FLAC file.
But still, there is no 100% safe methods detecting of FLAC source: mp3 or lossless audio. Because, processing can causes frequency distortions. In instance, audio optimization, cut all above 20 kHz to reduce some playback distortion for hi-res audio systems.

MQA is format supporting high-resolution. It may give some advantages, that high-resolution technologies bring. However, recording quality and implementation of used audio system is matter in comparison hi-res vs CD.
Decoding with spectrum unfolding of MQA let support high resolution audio. As hi-res format, MQA allows using abilities of such type of audio in improving of sound quality.
Both MQA and FLAC support high resolution. However, FLAC is a lossless format. It means that both coded and decoded binary content are identical. But, as far as the author know, Master Quality Authenticated is not a lossless format in this meainig. However, MQA provides high sound quality. Thus, we can compare certain recording played back on certain hardware/software.

LDAC operate on Bluetooth at bitrate up to 990 kbps 24bit / 96kHz. CD quality is about 1411 kbps.
CD quality is transmitted losslessly. 24/96 is transmitted with losses but in high quality [*].
LDAC codec for Bluetooth provides bitrate (24bit / 96kHz, up to 990 kbps).
aptX HD provides 24-bit / 48 kHz with maximum bitrate 567 kbps.

LDAC and AAC are used in Bluetooth wireless audio connections (speakers, headphones).
AAC provides bitrate up to 250 kbps (96 kHz), LDAC provides up to 990 kbps (24bit / 96kHz).
We can consider LDAC as better codec due to higher bitrate. But actual result is implementation defined.
There are several aptX codecs. It defines result of comparison with LDAC. See details...
LDAC is a codec for wireless audio (Bluetooth). The codec provides higher bitrate (24bit / 96kHz, up to 990 kbps) of transmitted audio stream.
It means that it is not only compression, but transmit syncronization.

On moment of this answer writing, the Spotify uses lossy codec (AAC up to 256 kbps). It is high qualitative audio format.
CD quality audio is lossless sound format. And it's better AAC technically.
But, you can don't get audible difference between these formats.
Yes. Apple music have hi-res audio coded to lossy AAC and lossless ALAC (up to 24-bit / 192 kHz)[*].
Target bitrate of apple music is 256 kilobits/second. It uses variable bitrate (VBR) to more effective compression.
No. Apple Music don't use FLAC format. They use ALAC instead[*].
No. LDAC is Bluetooth codec. Apple uses AAC and ALAC[*].
Yes. YouTube supports hi-res audio[*].
Look at list of hi-res streaming...
No. On momemt of the answer writing, YouTube doesn't support 32-bit audio[*].
No. YouTube stream lossy audio on moment of the answer to the question[*].

- Frequenze di campionamento più elevate non sono destinate alla registrazione degli ultrasuoni. Permette di risolvere problemi di filtraggio analogico e digitale di convertitori analogico-digitale (ADC) e digitale-analogico (DAC).
- Profondità di bit più elevate non servono a fornire un livello sonoro superiore alle soglie dell'udito umano. Tali profondità di bit garantiscono un rapporto segnale/rumore adeguato per i segnali musicali più silenziosi. È importante per alcuni generi musicali (classica, jazz, audio cinematografico, ecc.).
- Ora risparmiare spazio non è più così attuale come prima. Tranne i dispositivi portatili. Tuttavia, il valore inferiore del flusso di bit (bit al secondo) è ancora effettivo per lo streaming di rete. Quindi la compressione dei dati ad alta risoluzione è molto richiesta.
- L'audio ad alta risoluzione migliora (potenzialmente) alcuni problemi di distorsione non lineare. Per una migliore naturalezza, anche la riproduzione spaziale del suono (campo delle onde acustiche) dovrebbe essere migliorata.
