beginner 
Hi all, I have pengutronix linux 3.1.1 installed on my mini2440 board, I need to make a Qt app which can mix several pcm or wav files with different pitches and volumes and put the resulting stream to the ALSA driver (ALSA works fine, I tried with madplay and aplay in console) I'm confused about what library to use and how to organize this. there are several ways OpenAL, fmodex, pulsesound, phonon, directsound, but I'm don't know exactly which one would be best to use in this case, I think OpenAL is easy and light one but I have absolutely no idea how to implement it to my Qt app. Please help. Thanks.
