tracking bpm


    Feb 28 2007 | 6:29 pm
    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!

      was supposed to be in the Max/msp forum, sorry for that.

      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?
