I use something called mpg123 for decompressing MP3
streams. It's actually a (command line) application, but it's
built on top of a 'C' library that should do what you need. It
is LGPL.
You will probably need to do a bit of digging around in
their SubVersion repository to figure out exactly what bits you need.
Don't expect to get it working in an afternoon. And you might need to step
over any ID3 tags in your MP3 files, I'm not sure if they've fixed that since
the version I'm using.
HTH.

Subject: Playing multiple MP3 songs simultaneously on
iPhone
Hello !
I would
like to do a mixing table on iPhone. I have the different
tracks of one song
and I want to play them on iPhone simultaneously.
These songs are MP3 files,
I want to be able to play up to 15 tracks
simultaneously, and changing
volume, muting some tracks, navigating in
the total song, etc.
Apple
MultichannelMixer example seems to do exactly what I want, but
MP3 files need
to be decompressed before being played. They seem to be
decompressed to CAF
files, and take a lot of space in memory (my songs
can last up to 5
minutes).
I tried SpeakHere example too, and use AudioQueue. I tried it
with
playing 6 AudioQueues simultaneously. It seems to work on
the
simulator, but I don't know if it will work on the device, and if
it
can do what I want.
I don't know what is the best way to do this...
Can anybody help me
?
