There are also some code examples in the Core Audio SDK - /Developer/
Examples/CoreAudio
What you'll need to do is to use a mixer audio unit - that takes one
or more inputs and mixes them to produce a single output - if you are
just doing stereo output, the stereo mixer is the best option.
You can use the AUGraph API to help to assemble this kind of
processing graph
As to what you would use for each input of this graph, it really
depends on where the data is coming from. If its from a file, then
you can use the Extended Audio File API in Tiger to convert the
file's contents into a format appropriate for the mixer (generally
this will float 32, deinterleaved - this will make sense when you've
read some of the documents)

i want to write an appplication using cocoa and core audio apis to
play one
up to maybe 10 or 20 sounds synchronously.
i know cocoa quite well, but core audio not at all.
(i read, nssound is not sufficient to play sounds synchronously.)
is core audio the right tool. or should i use something different,
maybe
more easy?
where can i find core audio documentation?
