I dug up my two-year-old audio parsing code today, and figured I should share it - what better place than the corresponding two-year-old CD thread?
Here it is:
http://stanford.edu/~sebell/tmp/findaudiomarkers.zip
The code is a simple script that reads an audio marker and can generate a noisy audio clip with the audio embedded. From there, it uses cross-correlation to locate the marker within the clip. Test data includes a couple clips from a real match, and it appears to work correctly on this data.
It's written in MATLAB, but should run with Octave. Anyone here is welcome to use and extend it. Let me know if you have questions or suggestions!
