in the VoiceProcessing mode but we would like to
avoid the overhead there and just configure Speaker route based on selected
input mic (to avoid feedback).
Thanks in advance

would be an alternative for ExtAudioFileWriteAsync?
I have been looking at Audio Queue Services for months but
documentation/examples are so old that it keeps me away from it… or should we
dive in?
Thanks in advance,

Any hints?

), I stop
the AUGraph, Update Stream Formats, Make Connections, Initialize AUGraph, and
run AUGraphUpdate and then re-start the graph. I guess the ordering here is
also important.
This said, we are both in the danger zone since AUGraph is doomed for
deprecation. Any updates on this?!

Benjamin and list,
I double Benjamin’s request. It would be great if someone from the CoreAudio
Team could respond to the question.
Two years ago, after basic tests I realised that AVAudioEngine was not ready
for Low Latency Audio analysis on iOS. So we used AUGraph. I have a feeling

Hi Dean,
What AVAudioSession Category/Mode are you using? Beyond this, you should
probably tell us how you record (AVAudioEngine? AUnit?).. My first suggestion
si to check the Stream format of your audio chain with that provided by the
system (such as sample rate etc.).
Do you mind sharing

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).

Do not post admin requests to the list. They will be ignored.
Coreaudio-api
on these observations it would be great.

o APIs. But you might wanna start
shopping on AVAudioEngine as it’s gonna be time to move soon after adoption of
Catalina/iOS13 in a few months.
Any further insight from other users would be welcome. I’m going to start
testing the Sink and Source nodes for real-time use soon.
Cheers,

Thank you Dominic for sharing this.
Is this general to both OSX and iOS or an OSX issue only? on iOS we can manage
to route audio using AVAudioSession. I’m not an OSX guy that’s why I’m asking
and before I move everything to AVAudioEngine!

We also use a simple measurement mechanism which is fine for a user-facing
situation.
However, what Brian described remains a problem: Doing such measurements when
user is using a Headset doesn’t make sense!
This is especially problematic for Bluetooth devices: I haven’t figured out a
way to

Just out of curiosity, what is your AVAudioSession mode? What if you use
internal speaker/microphone?

Fred,
To my knowledge, you can not explicitly do that with AVAudioSession. Even the
setPreferredDataSource’s location setup can be misleading: Everything depends
on the Polar Pattern you choose. So an Omni Polar Pattern on “Front” will
result in using two microphones to achieve it. There is
but sometimes easily missed).
Hope this helps. Let us know!
