5 THE PRO-CODEC PLUG-IN
5.9.4 Internal Dither and Truncation
The previous examples include the insertion of a dither/truncation plug-in in the audio
path to provide correct treatment of the signal prior to the codec. For convenience, if a
dither plug-in is not available, the 16/24 bit dither option can be enabled in the codec
settings selector.
Note:
If the plug-in is subsequently bypassed to render to WAV, the resulting output will not
be dithered and truncated correctly.
