tracking bpm

Hi all,

is there maybe a possibility to see the bpm of a music sample that is playing in a groove~ object.

If I change the speed/tempo of the playback will I be able to see how the bpm are changing??

Thank you in advance!

one method:

First you need to convert the beat you wish to calculate into a bang
(typically the kick drum) using ‘bonk~’ or filter out the kick with
biquad~ and detect with thresh~ — then use the ‘timer’ object which
will give you the ms between beats, then calculate ms to bpm

Well, I think the timer object is pretty crappy if you accurately want to calculate the time between two events. Not that I have a better solution, but maybe somebody here has any ideas on how to make a “timer”-like patch, but then in audio-rate?
