Hi,
Is there any way to get Core Audio to only send from one speaker on the
iPhone 7 (and newer)? For example, setting
AudioStreamBasicDescription.mChannelsPerFrame to 1 or 4, or some special
function in AVAudioSession? I have been digging but I can't seem to find an
answer to this. I would test these ideas myself but my phone is older, so
there's nothing I can seemingly reproduce here.
My application requires that sound only be sent from one speaker. Two
speaker playback causes destructive interference. From my understanding,
the 7 will correctly separate two channels in landscape mode, but I suspect
it may mix the channels and play from both speakers in portrait.
Thanks
Brian
