Resample
This control affects how PCM audio data is manipulated to match the
variable video delay through the synchroniser. When resampling is
enabled, the audio is continuously resampled with a variable speed clock
allowing seamless changes in audio delay. To minimise audible pitch
changes, the maximum frequency distortion is limited to 0.8% which
means a sudden 40ms change in video delay will require five seconds for
the audio to catch up. If resampling is not enabled, audio samples will be
passed unchanged through the signal path and, if the delay has to
change, single audio samples will be dropped or repeated as required.
This control has no effect on channels containing Dolby E which is
automatically detected and bypasses the resample process.
Dolby E
On when an audio input pair is Dolby E encoded.
