Wow, that's a lot of really prompt replies. I'm impressed! I've got
a load of beat times out of the file using aubioonset (thanks to
everyone who suggested looking at aubio). Now I need to identify
which of these beats are actually on the beat of the tune, as opposed
to grace notes etc. Are there programs or algorithms to do this? I
surely can't be the first person to need this.
Thanks again for all your help.
