I'm using OpenAL as the sound engine for my iPhone game, but still learning how to use it. I managed to play sounds with it, however I'm in one point when I need to concatenate (not merge) 2 sound sources (same file in fact, so this needs no conversion I guess) and I'm stuck. Any help would totally be appreciated:D
I wonder if you landed on this: OpenAL Programmers Guide
Try looking into ExtAudioFile.
