And as demo’ed in this video, Blender can be used as video player for Audacity(as long as you use the play/stop button in Blender): https://blender.chat/file-upload/4rjJTpPHLK5M7NBXY/2021-03-16%2018-59-15.mp4
Unfortunately, there doesn’t seem to be a way to send the playhead position from Audacity to Blender, so the playback could be initiated from Audacity too.
@steve Is there some gain added when audio is imported and exported in/out of Audacity?
Here’s the same strip in Blender, however the top one has been send to Audacity and back:
We already noticed it when importing into Audacity, that some red lines appeared, which wasn’t in Blender, so we compensated by adding envelope points to all strips lowering the volume a bit. The image above, is with this implemented, so there must also be some gain on exporting?
Is this a know thing? And if it is, how much do we need to compensate i/o?
When adding mono audio to a stereo track, the expected behaviour is that the same, unaltered audio will be added to both left and right channels.
When exporting a stereo track as mono, the expected behaviour is that the left and right channels will be mixed (added together) then scaled by a factor of (exactly) 0.5. If the export format has a lower bit format, then there may be “dither” added (shaped noise at around -72 dB peak), depending on your settings (see: https://manual.audacityteam.org/man/dither.html)
