Answer 1

You could, if you implemented your own mixer. Just playback a buffer and mix the audio yourself. It' basically boils down to just averaging two different amplitudes. In some cases it's a bit more advanced.

Answer 2

Check out the AVAudioPlayer class. It will do what you need.

One thing to be aware of is that this class will only play one mp3 format sound at one time. I suggest converting to IMA4 format if you are using mp3 and need to play multiple sounds at once.

You can use the afconvert command to convert between sound file formats.

AVAudioPlayer is available in firmware 2.2+.

Answer 3

If you are using cocos2d 0.82, then you can use denshion for this.

Play background music: [[SimpleAudioEngine sharedEngine] playBackgroundMusic:@"somemusic.mp3"];

Play SOUND EFFECT: [[SimpleAudioEngine sharedEngine] playEffect:@"mysound.wav"]
