Reading in audio data in a plugin?

(1/1)

Matze88:
Hello!

I would like to write a plugin that demodulates different signals from incomming audio (linein, mic, fmradio). What is the right way to access that data in a plugin? Should I use the "recording" functions (those around pcm_init_recording() ) or is there an easier, better way to get that data? I need the "real stream" means every audio sample, the oscilloscope plugin for example just uses pcm_calculate_peaks which does not return sample data, does it?
Maybe anyone of you has a short example for reading in audio data in a plugin? At least some tips which functions to use would be very helpful.

Thank you very much,

Matthias

Matthias, welcome.  You are welcome to post this type of question here, and it may be that you get a helpful response.  However, many of the developers do not read the forums, so you may find the #rockbox IRC channel or the developers' mailing list more useful.  You can find links to both under the "Support" heading on the left.
