Tips and tricks:

Dithering is applied on extracting to 16 bit FLAC only. If target FLAC resolution 24 bit and more (including float point), Dither button is ignored.

 

In the Settings > General tab:

  • FLAC compressing slider: set several levels of FLAC compression. As rule, slider position altering give minimal effect. Central slider position is recommended.
  • Filter mode list: "Optimized resampling filter" is recommended. "Non-optimized ..." and "Non-optimized wide..." may cause noise and distortions.
  • Use minimum phase filter... switch unchecking is recommended.

However, here are not rules. Your individual choices may be other, than recommended here.
