iOS Question Capture audio data from microphone

[Cadenzo]

Is there a way in B4i to capture the microphone wave data directly in a int or byte array? In B4A we have the very good solution with the audiostreamer and the event RecordBuffer in the Audio or AudioRecord library.

It is very importent for any form of noice or frequency analysis. There are already some iPhone apps like intrument tuners, so it should be possible in iOS. But how to access the mircophone data in B4i?

Currently you can only save the recorded stream to a file.

OK, than it could be a kind of solution, to save the recorded stream to a not compressed .wav file and access the file in the same time?
I have to check, if it is possible.

Are there any audio libraries planed in future? Could this be imported to B4i?

Set MPEG4 parameter to False. If I remember correct the file extension affects the format. You need to check it.

AudioRecorder is based on AVAudioRecorder. It will probably be extended in the future.
