  2. Click Open files button and select input DFF files;
  3. Select DSF output format, target sample rate (2.8 MHz is DSD64, read more about sample rates);
  4. To convert .dff to .dsf with identical quality, in Settings > General > check "Don't make DSP..." switch and select target sampling rate "as input".*
  5. Select the output directory.
    In main window of the conversion software (left lower part), use Directory output files field.

Sound quality

To provide lossless (bit-perfect) conversion:

  • In Settings > General > check "Don't make DSP..." switch.
  • Select sample rate and bit depth "as input".

When the conversion is performed with resampling, there are some losses (distortions). A sound conversion tool defines the distortion level.

The darker background means a lesser noise. Lesser noise means a higher sound quality.



DFF file doesn't provide metadata (track name, album, performer, etc.). Metadata may be assigned after conversion to DSF files.
