file format for sound?

Hello,

 I am still starting with Core Audio.  I was wondering if there is a file format I might use for my videogame, which encapsulates sampled sound with sequencing information to reproduce a song?  I think that might be what a MIDI file does, though I am fuzzy on how samples play into it, are they/can they be included?

Then, what tools can be used to make songs and save in that format?

Alternatively it seems like much game sound is maybe done with aiff or mp3 if it is a longer sound, like an entire song?  I have had some success with MP3 playback starting from that Mixer sample code, but those mp3's are only seven seconds long.  I haven't gotten it to work with an entire 4MB song -- should I be able to do that using Audio Units on iphone?   What is the best way of playing mp3 songs via Audio Units, if I have a whole Audio Graph and other sound effect channels etc?

Thanks
Bob
