Hi Everyone,
I am looking for the input-ouput sampling rate capabilities
of the hardware on all iphone, ipad, ipod touch (all generations). What is the
array of supported sampling rates?
Minimally does all the iOS devices support 24 kHz and
48 kHz? I know that I can use a converter Audio Unit to support these, however
I would rather not spare CPU time doing resampling and try to run at native
sampling rate.
Also, is there another way of setting IO buffersize
than calling AudioSessionSetProperty with kAudioSessionProperty_PreferredHardwareIOBufferDuration?
I find this a bit cumbersome to pass a time in seconds rather than in samples.
Thank you,
Stephane
