get wavform from movie

I have an mpeg4 I recorded in OF and want to set points from the audio timeline. I am loading the movie into and ofxTimeline instance but want to see the audio waveform. Does anyone have any tips.

What OS are you using? I know this is possible on OSX, but that it’s pretty tricky and requires some mucking around with QTKit. I’d guess it’s similarly possible but difficult on other OS/Video Library combos as well.

I am on OSX. Cheers.
