In the conversion software's main window click Settings button. Appear Settings window. In Settings window > General tab > FLAC compressing slider. Compressing level doesn't impact sound quality.
FLAC specification (see link below) allows using sample rate up to 384 kHz and bit depth up to 32-bit integer. Float point bit depths don't supported.
When software converts DSF (DSD file format) to FLAC, it adds distortions anyway. In general, the distortion level is comparable with resampling. The most important feature of the conversion software is the distortion level.
In ideal case, should not be repeatable lines with lower brightness. These lines show audible distortions, that correlate with original signal.
All AuI ConverteR’s editions have identical sound quality (fully identical digital signal processing).
Difference in functional restrictions Free and commercial versons see here...
Conversion 1-bit audio to PCM, considered in the article, is filtering with dividing sample rate (decimation). The quality of DSD-audio decoding to PCM is defined by quality of the filtration. See details by link about DSD demodulator below.
Some albums must be playback as continuous music stream: operas, musicals, live concerts and others. Non-zero levels are possible at track borders. If a conversion software re-initialize processing at each track, artifacts appear at the borders. The converting software has functionality to process all album tracks as a single audio stream. Processing initialized once - at the begining of the album.
DSD stuff has a headroom of about -6 dB, as rule. It is solving DSD modulator's stability issue. Auto-level normalizing allows automatical compensation of the headroom and maximally (0 dB) increases the peak level of converted PCM audio stuff.
Oversampling can cause overload too. Auto-level normalization fix it.
The conversion software has several types of resampling filters:
In some music systems, "Non-Optimized..." modes can cause audible noise (see video).
In general, "Optimized..." mode is recommended.
These modes are selected in Settings > General > Filter mode.
