Conversion sound quality

Main priority of AuI ConverteR is sound quality - keeping (as possibly) converted signal unchanged.

Conversion to/from lossless PCM format (Free Lossless Aaudio Codec, WAV, AIFF, ALAC and other) without resampling and bit depth altering is simple repacking and don't change sound quality.

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
