Hey all,
So Im working on an app that is very audio driven. one of the things that i need to do is when a slider gets moved to start looping a sound and then adjust the volume of only THAT sound according to the slider and then once the slider is back at 0 to finish the effect and stop looping it. How could I do this?
Thanks

Check out the latest version of CocosDenshion (called Aphex) http://code.google.com/p/cocosdenshion/
It has a new class called CDSoundSource which is like a beefed up version of CDSourceWrapper that would be perfect for this.
If you know how to use svn you can get the code now, otherwise wait an hour or two and I'll have a download available.

Yes, look at the FadeToGrey example under TestsAndDemos.

No there is no master pan, what would master pan do?

Imagine I have three sound sources defined one with pan -0.5, one with pan 0.0 and one with pan 1.0. I then set master pan to 1.0 - where would those three sounds appear in the stereo panorama?

AVAudioPlayer (which is used for background music) doesn't support panning. You could simulate it by using two AVAudioPlayers and adjusting their relative volumes. CDAudioManager already supports this with two "channels" of playback. However, bear in mind that you can only have simultaneous compressed audio playback using AVAudioPlayer on 3.x OS and then only one of the players will be using hardware decoding, the other will be decoded in software which is CPU intensive.
Edit: you would also need two copies of your audio file. Both in stereo but with either the left or right track silenced.
