Digital Audio File/Quicktime Help

[FMoyer at aol.com]

Is there anyone out there who knows the insides of digital audio files? I am 
writing an application where it would be helpful to be able to manipulate 
these files. For example, I'd like to create a new sound file that consists of 
just a portion of a larger sound   file. I have no idea if it is even possible to 
dig inside a sound file without messing it up.

I would also like to find someone who knows the insides of Quicktime. I am 
needing to use Quicktime in some slightly unorthodox ways. For example, I need 
to allow the user to click a mouse to play a portion of a Quicktime file with 
no time lag -- in other words as soon as the user clicks the mouse, the music 
plays.

Thanks
