FLAC Format Preferences allow setting up how output FLAC files are encoded. This tab allows specifying Bit Depth, Compression Level, Sample Rate and Channels.

Open the FLAC Format Preferences tab, choose ‘Preferences’ in Application Menu and select the Format tab.

Bit Depth

Select ‘As Source’ when the Bit Depth should be assigned to 8, 16 or 24 bit, depending on the bit depth of source audio. ‘As Source’ is the default preferred setting.

Sample Rate

Select ‘As Source’ when encoded audio should have the same sample rate as source audio. This is the default preferred setting.

A fixed Sample Rate also can be set from 8000 to 192000 Hz. If the Sample Rate of source audio differs from the selected fixed Sample Rate, the output audio will be resampled.

Channels

Select ‘As Source’ when encoded FLAC audio should have the same number of channels as source audio. This is the default preferred setting.

A fixed number of channels also can be set to:

  • Mono (1 Channel). If the source audio has more than one channel, it will be downmixed to mono in output FLAC files.
  • Stereo (2 Channels). If the source audio has more than two channels, it will be downmixed to a stereo in output FLAC files.

  • Vorbis - encoded FLAC files will contain Vorbis tags only. This is the default preferred setting.
  • Vorbis, ID3v2.4 - encoded FLAC files will contain both Vorbis and ID3v2.4 tags.

The Tags Format has no effect when option 'Strip tags from converted files' is enabled in Preferences / Tags.
