If that article's really from Feb 1999, it's way, way out of date! Try this instead:

http://developer.apple.com/referencelibrary/GettingStarted/GS_MusicAudio/index.html

I've tried to read from a sound file and play it using SndStartFiiePlay only to find that it's been deprecated.  The guy on the quicktime list said I should use the AudioFile APIs instead.  What in particular should I do?


Download the CoreAudio SDK from ADC. It installs into /Developer/Examples/CoreAudio/. There are some examples in there that show how to play an audio file using a file-player AudioUnit.

It does take significantly more than one line of code. You could do it in 2 or 3 lines using the higher-level QTKit API, but that's Cocoa, not Carbon. (Is this a new project without a lot of legacy code? Personally, I'd highly recommend using Cocoa instead of Carbon, as the frameworks are much higher-level.)
