Need OSX code to process audio stream of an .m4v movie file

I need to process the audio stream of an .m4v movie file?

Can anyone get me started?

This is my first go at an osx project, up till now I've only done iOS

( specifically I need to examine the audio stream for a beep, which is well defined. if I can get the audio stream as a bunch of floats or ints I should be able to extract it without too much trouble )

Solution

  • There is plenty of sample code for working with audio at developer.apple.com.
