Hello,

For a research project, we need to tap the sound output of an iPhone (output after the volume control of the device) and write this into a buffer (raw data) for further analyses (e.g. FFT).

Is there a simple way to do that? once this is possible, we can then link the rest of our application to this

Thank you in advance for your advice,
