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

To open FLAC Format Preferences tab, choose ‘Preferences’ in Application Menu and select 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.

Compression Level

Specifies the value of compression level and selects the algorithm allowing to encode audio with the best compression or with the best speed. The default setting is ‘High’ which means highest compression level is in use.

 

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 selected fixed Sample Rate, the output audio will be resampled.

Channels

Select ‘As Source’ when encoded 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 a mono.
  • Stereo (2 Channels). If the source audio has more than two channels, it will be downmixed to a stereo.
