[Alsa-user] I/Q Sampling

[Michael Di D. <mdi...@gm...>]

I'm a newbie to alsa programming.  Can anyone point me towards/give me
some sample source code (C/C++) that shows a short and clear
(preferably documented) example of how to read the left/right channels
from an alsa device, and then convert them into a I/Q complex stream
for processing?

I see there are a few examples on how to read data from an alsa device
on the web, but I'm not overly clear what I'm getting when I read in
the bytes and how to convert them into I/Q streams.

thanks
