Ability to change input/output volume of AudioUnits about theamazingaudioengine HOT 4 OPEN

Doesn't -[AEAudioUnitChannel setVolume] handle this?

from theamazingaudioengine.

So this is the output volume of the channel, correct? In theory you could manage the input volume by knowing the make-up of the graph and appropriately adjusting the output of the "thing" that is being input to this channel. However, it would be nice to not have to know that - what if you have multiple "things" connected to this input? For instance, if you have an AudioUnit that you know needs 3db of headroom to do its best work, it would be helpful to be able to adjust the gain on the input to that audio unit to -3db regardless of what is connected to that input.

Does that make sense? Or is my understanding wonky? :-)

Ah, you're referring to audio unit filters (AEAudioUnitFilter), not channels, I think. It sounds a bit hacky, adding gain settings to filters like that - if the audio unit requires certain input/output parameters, is there not a way to specify these on the audio unit directly? Sounds like an audio unit bug if not!

I'll be digging into this again after this week and will report back with more detail.
