DFF to DSF converter. Sound Quality
Sound quality: AuI ConverteR vs a converter software: DSD64 to DSD128 noise
In the ideal case, should not be noise in the audible band. Lesser noise (darker background) means a higher sound quality.
True Gapless Mode resampling albums (operas, live concerts, musicals, etc.) as a solid stream without artefacts on neighboring track borders. See the main software window > Parameters tab.
The pure signal on border of two neighbor tracks, when True Gapless Mode turned ON.
If tracks are processed as separate files at the track border artefacts (noise splashes) appears due to processing re-initialized at beginning of the track. To avoid it all album tracks should be processed as a continuous stream without re-initialization.
In True Gapless mode, the converting software processes album tracks sequentially. Because to convert the next track, it needs to have processing state of the previous track.
Auto level normalization allows maximizing of loudness without overload.
Resampling can cause overload. Overload can cause distortions. Manual gain control can solve the issue. But auto level normalization makes it automatically and keeps your time.

The mode activation: open Settings window > General tab. "Don't make DSP..." switch must be checked (turn ON).
