Sample rates 44.1, 48, 88.2, 96, 176.4, 192 kHz, 352.8, 384, 705.6, 768, 1411, 1536 kHz are converted. The sampling-rate range is limited by format. FLAC has 384-kHz limitation. Multichannel files, export meta tags to target files are provided.
 

How to convert 32bit FLAC

To convert from/to 32-bit FLAC file:

  1. Run AuI ConverteR 48x44


     
  2. Open audio file (32 bit FLAC or other) *
  3. Select:
    - target file format,
    - sample rate,
    - bit depth (up to 32bit for Free Lossless Audio Codec)*
  4. Select target directory in "Directory of output files" field of the main window of the software.
  5. Push Start button and wait of conversion end.

 

* 32-bit resolution support depends on configuration. Free version has limitations: 2-second silence in the middle of the output track.

Conversion sound quality

Main priority of AuI ConverteR is sound quality.

Conversion to/from lossless PCM formats (Free Lossless Aaudio Codec, WAV, AIFF, ALAC, and others) without resampling and bit depth altering is just repacking. It doesn't change the sound quality.

But, some kinds of conversions have unavoidable losses. The converter program try minimize it as possible.

 

 

Watch and share: WAV and FLAC are binary identical or not?

Resampling cause some losses. Resampling quality depend on implementations. Resamplers' comparison here

But for some cases resampling may be useful.

32 bit 384 kHz FLAC is maximal resolution of Free Lossless Audio Codec.

When digital signal is converted to analog into Digital Analog Converter (DAC), usually, audio data from music file is upsampled to higher sample rate for digital filtration before analog filtration.

Analog filtration restore analog signal from digital signal. We can say, that analog filter connect "stairs" of digital samples via uninterrupted flexible line.

But for analog filter it is very hardly to achieve deep filtration of aliases (distortions) during digital-analog conversion. Therefore before analog filtration, deep digital inline ("on fly") filtration is used.

Non-filtered ultrasound can cause playback audible noise at some software/hardware due intermodulations.

AuI ConverteR 48x44 makes deep filtering of aliases during offline (non-realtime) oversampling with "heaviest" math. Also it have optimized mode (used as default) to remove ultrasound.  Other words it allow to do "half of DAC's work" with very accurate offline algorithms.

Utrasound filtering may be switched off (Settings > General > set Filter mode in "Non-optimized...").

32 bit 384khz DAC allow to use maximal resolution of Free Lossless Audio Codec. However, 24 bit FLAC is more popular for download from stores. There is no univocal answer, need to convert lower bit depth to 32 bit or not.

Watch and share: Experiment with ultrasound filtering to fix audible noise

Are FLAC files 16-bit?

Yes. FLAC supports 16 bit resolution.

 

What bit rate is FLAC?

FLAC bitrate depends on channel number, bit depth and sampling rate.

As example, uncompressed FLAC bitrate for 1411 kbit/s ≈ 2 channel x 16 bit x 44100 Hz.

If FLAC is compressed, bitrate is 0.847 kbit/s ≈ 1411 kbit/s * 0.6 (approximate compression rate).
 

Is FLAC better than 320 Kbps?

FLAC is lossless audio format. 320 kbps is refer to lossy formats mp3 and AAC.

So, technically, FLAC is better than 320 kbps formats by sound quality.  Other factors are there too.

Lossy formats has lesser size than lossless ones.
