Hello list,
I am testing the quality of Echo Suppression in VoiceProcessingIO subtype of
AudioUnit.
I realise that I do not have the same quality from device to device, which I
can partly understand.
What I see most is this: In a “double-talk scenario”, I get more muting on
iPads than iPhones. Even on iPhones this differs from model to model and
“iPhone X” does not seem to be best on my list! It seems to me that there is
“muting” on top of an adaptive filtering in action here. I have been playing
around with available parameters (such AGC) which obviously have no effect in
controlling the quality / muting. Thus my questions:
* Is there a way to control the Muting effect?!
* Is there a way to control the overall Quality? I know that there is a
deprecated parameter on this. I assume that CoreAudio now chooses that
parameter based on device/context capacities. I understand this design choice!
But it’d be great to let developers “pay” for what they ask (meaning I gotta
optimise more to get better stuff, if possible).
Cheers,
Arshia Cont
