Sound quality of DSF to FLAC Conversion

When a software convert DSF to FLAC, it add distortions anyway. In general, the distortion level is comparable with resampling. Most important feature of the conversion software is level of the distortions.

All AuI ConverteR’s editions have identical sound quality (fully identical digital signal processing).

Difference in functional restrictions and available formats, sample rates, etc.

Conversion 1-bit audio to PCM, considered in the article, is filtering with dividing sample rate (decimation). Quality of decoding 1-bit audio to PCM 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 other. Non-zero levels possible at track borders. If conversion software re-initialize processing at each track, artifacts appear at the borders. The converting software have functionality to processing all album tracks as single audio stream. Processing initialized once - at begining of the album.

DSD stuff have headroom about -6 dB, as rule. It is solving DSD modulator's stability issue. Auto level normalizing allow automatically compensate the headroom and maximally (0 dB) increase peak level of converted PCM audio stuff.

Oversampling can cause overload too. Auto level normalization fix it.

The conversion software have several types of resampling filters:

  • "Optimized resampling filter" eliminate frequency range above 20 kHz;
  • "Non-Optimized resampling filter" eliminate frequency range above 20...24 kHz (depend on input/output sample rates);
  • "Non-Optimized wide resampling filter" eliminate frequency range above 20...100 kHz (depend on input/output sample rates).

At some music systems "Non-Optimized..." modes can cause audible noise (see video).
In general, "Optimized..." mode is recommended.

These modes selected in Settings > General > Filter mode.

 

 


Features

  • DSF to FLAC converter with studio quality

  • Downmix 5.1 to 2.0
  • Transfer metadata (artist, album, track name, year, artworks) from source to target stuff
  • By user option can be selected optimized or non-optimized mode
    (frequency band limitation to avoid audible intermodulation distortions at some equipment)
  • Built-in metadata editor (text and adding/removing artwork) edit as group as individual album track

In the conversion software's main window click Settings button. Appear Settings window. In Settings window > General tab > FLAC compressing slider. Compressing level don't impact to sound quality.

FLAC specification (see link below) allow to use sample rate up to 384 kHz and bit depth up to 32 bit integer. Float point bit depths don't supported.
