DFF to DSF converter

1. DFF to DSF converter stereo and mulichannel files (D64/128/256/512/1024 or 2.8/5.6/11.2/22.5/45.2 MHz).

2. Accurate resampling during conversion.

3. True Gapless Mode resampling albums (operas, live concerts, musicals, etc.) as solid stream without artefacts on neighboring track borders. See the main software window  > Parameters tab.

True Gapless Mode

Pure signal on border of two neighbor tracks, when True Gapless Mode turned ON.

If tracks processed as separate files at track border appear artefacts (noise splashes) due processing re-initialized at begin of track. To avoid it  all album tracks should be processed as continuous stream without re-initialization.

In True Gapless mode the converting software process album tracks sequientally. Because to convert next track need to have previous-track processing state.

4. Auto level normalization to maximize loudness without overload.

Resampling can cause overload. Overload can cause distortions. Manual gain control can solve the issue. But auto level normalization make it automatically and keep your time.

The mode available when input and output sample rates are equal. It is data container repacking.

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