What do I need to listen to hi-res music?

 

Playing top-notch audio on your gadgets

You'll need one of these:

  • a PC or Mac or
  • a smartphone or
  • a smart television or
  • an audio player or
  • a media server or
  • another suitable device.

For computers and phones, you must install special software.

If you're into DSD audio, check out these players for various devices.

Consider subscribing to a streaming service like Amazon, Apple, Tidal, or Youtube for online music in high quality.

Remember, streaming might not give you the highest sound quality. Some programs can improve it as you listen. It may be "on fly" resolution conversion with some software.

 

To enhance sound on your phone or portable player, you might want an external DAC (digital-toanalog converter device) with an amplifier. This is also advisable for PCs.

The quality of loudspeakers, earphones, and amplifiers will affect your listening experience.

List of high-quality audio player software

 

For wireless earphones and speakers, there are special Bluetooth options for better sound. aptX™ HD can handle 48 kHz / 24-bit LPCM data, while LDAC goes up to 96 kHz / 24 bit / 990 kbps. Sometimes we can see requests download free songs in 990 kbps. We should know to clear understanding, that it is inner format for hi-fi wireless connection. Learn more here.

 

Can smartphones play high-resolution audio?

Yes, both Android and Apple iOS phones can handle hi-res sound. To enjoy it, simply install this music app and dive into your beloved tunes.

Many smartphones come with a built-in app for playing music.

 

What's the best audio format to download?

Curious about the finest sound quality for downloads? Web shops provide tunes in various formats like FLAC, mp3, AAC, DSF, and more. For those with a DSD DAC, DSF is often the top pick.

Is mp3 a high-resolution format? Are there free high-res mp3s? Sadly, no. Mp3 is capped at 44.1 and 48 kHz / 16-bit.

How about downloading high-rate LDAC audio? That won't work either. LDAC is meant for Bluetooth streaming, not song files.

For the best sound, lossless formats (FLAC, WAV, AIFF, ALAC, DSD) are the way to go. Looking for free high-quality music? Check out these tracks.

 

Does FLAC have better sound than WAV?

Both FLAC and WAV are lossless, meaning they don't lose sound quality. FLAC is great because it:

  • Works well with different programs and devices,
  • Can natively handle files bigger than 4 GB.

Learn more...

 

WAV offers more flexibility than FLAC. It allows for:

  • higher sound quality levels, up to 2^32 Hz,
  • support for 32-bit float and 64-bit float resolutions.

Discover more...

 

Which is superior, AAC or FLAC?

FLAC is completely lossless, preserving sound perfectly. AAC is a modern format that's good quality but compresses files to save space.

 

Is high-definition audio only 24-bit?

No, HD audio includes at least 24-bit depth or frequencies over 48 kHz. Looking for 24-bit tunes? Start here...

 

Are 24-bit and 32-bit audio worth it?

It's not a simple yes or no. 24-bit matches well with many DACs and has some extra room.

32-bit and 64-bit are key in music creation, allowing producers to work almost without worrying about sound distortion.

Generally, you might not notice a difference between 32-bit and 24-bit. To really compare, try listening on your DAC. Want free music downloads? Find out here...

What is Hi-Res audio?

 

Hi-res audio explained

 

Below you'll read short explanation what is high-resolution audio. If you want to read tech details, study this article...

High-res essence:

  • High-resolution audio (hi-res audio, high-definition audio) is digital sonic format family. Their resolutions is above 16 bit/44.1 or 48 kHz. 1-bit DSD (Direct Stream Digital) is included to HD family.
     
  • Hi-res music is intended to get a better listener experience, than standard CD. It should be reached due to higher sound quality (SQ).
     
  • Hi-Res format is the common term between audiophiles, hi-fi vendors and music producers.

Modern videos has soundtracks in HQ, including surround capabilities.

 

Is high resolution audio a gimmick?

No. HD formats solve 44.1 kHz /16-bit issues. But, a high sampling rate and bit depth don't guarantee the best listening experience. It gives potential possibilities. Headphones, speakers, amplifiers, DACs, recording, mixing, mastering do the result.

 

Can you hear Hi Res audio?

These formats give abilities to get more "transparent" sounding. It happens due to higher sample rate and bit depth allows to achieve lesser distortions.

However, an equipment has non-linear distortions. And, some playback units may cause audible noise for certain high-resolution recordings. Actual result depends on the unit and their system implementation.

See video...

 

One of important questions is can you hear difference between CD and Hi-Res? We means ultrasound audibility that HD records should keep. According to the 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. But, science discovered new knowledge there. Learn more details...

You can try improve sound quality...

 

Is Hi-res audio lossless?

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 hi-resolution technically. Can you download high quality music? Yes. Start here...

 

What is hi res audio certified?

You can read about hi-res certification.

PCM vs DSD vs DXD vs Analog sound quality

And we should ask: is DSD better than PCM including FLAC? In the first approach, DSD, DXD, PCM formats give the same opportunities to designers of a music system. The 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 DXD have the "hump". For PCM, high-frequency noise is not issue.

We don't hear ultrasound. And this noise is not audible. Nevertheless, the system hardware and, sometimes, software have non-linear distortions. They can cause the generation of audible noise from the inaudible high-frequency components.

If you hear noise in hi-res audio playback, read what can be done...

DSD is not the best in comparison with PCM or FLAC. Many factors define distortions for both modulation types. Final result depends on the implementation and played back recording.
SACD is absolutely the same as DSD.

How hi-res works?

 

Hi-res audio music. Tech explanation

 

Digital-to-analog converter always has analog filter. The filter type has some limitations by suppression of excessive digital products. Hi-res audio expands audio signal band. It allows suppress the products more effectively. Study what occurs there...

 

Why does high resolution is need?

Hi-res audio was designed to provide better listener experience, than standard compact disk.

PCM 44.1 kHz / 16 bit vs. High resolution: PCM and DSD

PCM 44.1 kHz /16 bit vs Hi-Res PCM and DSD

 

Does music genres make matter?

Some kinds of music with a wide loudness range (like classical, jazz, soundtracks), demand a wider dynamic range of a recording and listening setups.
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. According to the current common theory, the audible range does matter. And, high-res doesn't add something to it. It is worth remembering, high sampling rates allow solving some distortion issues in the audible range.

 
High-resolution recordings were invented for music with a wide loudness range
High resolution music records

 

 

What is the highest sound quality?

If we have the hi-res now, we can also ask: what is the highest SQ?  In hi-fi, we look for minimum distortions. Higher sampling rates and bit depths give potential abilities to achieve better audibility. It means lesser distortions. Nevertheless, the actual result depends on implementation of audio equipment and software.

For understanding how implementation impacts the listening experience, 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 accuracy.

The same things are in the listening. Even if we discard ultrasound, HD data format with higher resolution should provide better accuracy 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, you do not need to particularly worry about signal processing in the converter. On the other hand, there are multiple factors, that can increase or reduce distortions.

What is noise floor? It is like water level in a pool.

Let's a sonic signal will be a ball in the pool. The upper part of ball may be visible.

The different signal levels are different ball's altitudes above the water level.

The ball may fully dive in the pool. And we can't see the ball's part above the water.

In other words, the signal under the noise floor is like the ball under the water level.

 

Resume

Lossless audio formats (FLAC, WAV, ALAC, AIFF, DSF) are recommended. However, lossy formats (AAC, mp3, etc.) with high bitrates (kbps) may save hard disk space. And they may be indistinguishable from lossless original files.

What is after hi-res sound?

The high-resolution formats 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...

Does 24-bit sound better than 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 reduce distortions.

Myths

 

Hi-res audio myths

 

Myth #1. High-resolution music has no sense because we can't hear ultrasound

High res is not intended to capture and play of ultrasound.

ADC and DAC contains an analog filters. The filters are not steep. For 44 100 Hz sample rate, They can't suppress aliases properly in the narrow band 20 000...22 050 Hz.

High sample rates causes placement of aliases at higher frequencies. It allows expand suppression band of the analog filter.

How it works:

  • digital filtering and decimation in ADC,
  • oversampling and digital filtering in DAC.

But, some improper filtering may occur due to limited computing resources of hardware.

Resume: High resolution is intended for analog filters in ADC and DAC. And ultrasound playback is only a consequence of higher sample rates.

 

Myth #2. High resolution have sense because it playback ultrasound

Practical experience, which may be checked right at home, says, that we can't hear frequencies above 16 ... 22 kHz.

There is a study:

  1. Toshiyuki Nishiguchi, Kimio Hamasaki, Masakazu Iwaki and Akio Ando: Perceptual Discrimination between Musical Sounds with and without Very High Frequency Components

This study found no significant difference between samples with and without very high-frequency components. The research authors cannot confirm or deny general human ability to discriminate the component presence.

 

Another hand, some researches, that studied ultrasound issues:

  1. Milind N. Kunchur, 2007: Temporal resolution of hearing probed by bandwidth restriction

     
  2. Lisa Zyga, 2013: Human hearing beats the Fourier uncertainty principle

     
  3. 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

 

The studies show brain response to ultrasound. But effects of inaudible frequences on hearing unknown.

 

Myth #3. Hi Res sound nicer (or closer to analog) because it cause lesser "stairs"

Digital signal doesn't cause "stairs" in any resolution. Because the analog filter at output works as an interpolator (connect momentary voltage values of samples via smooth curve).

Digital signal isn't stairs
Digital signal isn't stairs

For high resolutions, the interpolator (analog low-frequency filter) is easier to proper implementation (see myth #1).

 

Myth #4. We can compare 24 bit / 192 kHz versus 16 / 44.1, DSD vs PCM, etc.

For the comparison, the samples should be purified of other factors.

As rule, such comparison is seen as a blind test. Samples are provided by a label in different resolution. As an example, one album is downloaded in 24-bit/192 000 Hz and 16-bit /44 100 kHz.

But, it is impossible to record "clean samples". As an example, we split a signal from microphone to 2 audio interfaces. They work in different resolutions. But we can't split into two completely identical signals. The identity of two interfaces is also problematic.

Or a single sample is converted to test ones with a software. We don't know whether we compare converters or resolution.

When converted samples are played back at single DAC, it may work in different modes. It happens due to electrical circuit, data 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:

  1. Joshua Reiss, 2016: A Meta-Analysis Of High Resolution Audio Perceptual Evaluation

 

Myth #5. Hi-res records always bring the best sound quality

Sound quality depends on many variables:

  • recording,
  • playback,
  • mixing/post-production software and hardware tools,
  • skills in recording/mixing/post-production engineer,
  • recording and playback environment,
  • accuracy of resolution conversion;
  • etc.

Format/resolution is one of them only. No warranties, that DSD1024 will cause the best listening experience in comparison standard PCM 44/16.

 

Myth #6. Hi-res formats bring advantages only

No. High-resolution formats contain ultrasound. Theoretically, it does not matter for ears, because we don't hear frequencies above 20 kHz.

Practically, listening equipment and, sometimes, software causes non-linear distortions. It can bring audible products from inaudible high-frequency components. It is called intermodulation distortions.

Watch and share: How to remove audible noise of high resolution recordings
video guide how to remove audible noise
 

 

In general case, higher sample rates and bit depth guarantee nothing. The result depends on implementation.

A professional audio interface at 44100 Hz can give better listening experience, than a built-in sound card at 192000 kHz.

 

Myth #7. Resampling can't improve sound quality

Resolution altering (resampling) is lossy processing always. After upsampling no information is added.

But we can't consider a recording without playback music system. And the system may have different distortions for various resolutions.

So, we can optimize the recording to better playback mode: choose the resolution with minimal distortions.

To reduce conversion losses, conversion algorithm should be accurate.

High-resolution audio formats

High-resolution audio formats

Below we'll consider audiophile formats with and without audio data compression.

PCM audio

High-resolution PCM is supported by lossless formats: 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 D-A converters support sampling rates up to 1411/1536 kHz. High rate values are especially recommended for non-oversampling DACs.

DSD

DSD audio (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 (Super Audio CD) optical disk.

 

DXD

DXD (Digital eXtreme Definition) is a PCM format with a high sample rate, derived from Direct Stream Digital.

More about DXD see here.

 

 

FLAC

Lossless method to compress PCM up to 384 kHz / 32 bit. Read details here...

 

DST

DST (Direct Stream Transfer) is lossless data compression method for DSD (1-bit resolution) files. It's supported in *.dff format.

 

MQA

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 a data". Read details here.

 

LDAC

LDAC is an audio codec for the Bluetooth. The codec is intended to high-qualitative sound connection between mobile phone and wireless headphones or speakers, in instance. The codec's data compression is more effective than previous ones. Where to get music downloads in LDAC? It's a wireless codec for data transmission. These data are extracted from audio files in different formats. LDAC is uses for Bluetooth domain only.

F.A.Q. bitrate

 

 

Does higher Kbps mean better quality?

In first approach, bitrate (estimated in kbps, kBit per second) means how many information pass through within second.

Lossy files are size compressed source. For lossy formats, 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 production level is primary key of audio fidelity for any bitrate.

 

How many kbps is lossless?

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.

Conclusions

 

  1. Higher sample rates are not intended for ultrasound recording. It allows solving issues of analog and digital filtering of analog-to-digital (ADC) and digital-to-analog (DAC) converters. Headphones, speakers, amplifiers are important too.
     
  2. Higher bit depths are not for providing sound level above thresholds of human hearing. Such bit depths bring proper signal/noise ratio for quietest musical signals. It's important for some music genres (classical, jazz, cinema audio, etc.).
     
  3. Now saving space is not so actual as before. Except portable devices. But, lower bit stream (bit per second) value is actual for network streaming yet. So high-resolution data compression is very demanded.
     
  4. Hi-res audio improves (in potential) some non-linear distortion issues. For better naturalness, spatial sonic reproduction (acoustic wave field) should be enhanced too.
