Hey guys,
I'd like to do some realtime analysis on audio data from a mp3 stream while it's playing (on iOS).
I need to convert samples to PCM format, not a whole file. And I need the result in some kind of
in-memory-buffer for further calculations.
In the moment I'm using Matt Galagher's AudioStreamer and have access to the mp3 samples
(or aac). He's using the Audio Toolbox Framework (Audio Queue Services, Audio File Stream Services,…).
I am aware that this will probably cause performance problems, but it's a research subject and
I really need a starting point for this.
Thanks for any hint!
Best,
Benjamin
