[LAU] Q: HOWTO: extract the beat times from an audio track

[Jeremy Henty]

I want  to create an  animation for a  track my band recorded  and I'm
wondering how  to get it  in sync.  It's  a straight 4/4 piece  but we
weren't playing to  a click track so the  tempo varies slightly.  Most
of the advice  I get is "Open it in Audacity  (or similar) and eyeball
the beats from the waveform" but it would be very cool if there was an
app that could read the audio and spit out the beat times.  Is there?

Regards,
