According to this report I got, the plugin audio callbacks aren't included for the recording functionality.

First I thought it'd just be about some pre-/post-callback entry point, however given that the recording does work per serverConnectionHandlerId and in this particular case the effects are done already onEditPlaybackVoiceDataEvent I can only assume the recording has a completely own mixing chain for some reason.

Since I'd rather not reimplement the recording functionality, I'd like you to have a look if this is perhaps just some oversight.
