Howdy there,

Is it possible to create a patch that calculates the BPM of an audio file being played from an sfplay~ object in real time (with as frequent a refresh as possible and as accurate as possible)? If so how on earth can it be done? Have been struggling with tempo~ to no avail.

Help please!

Beat tracking is not the easiest thing to do reliably. Tristan Jehan’s
beat~ does a fairly good job and might be what you’re looking for. You
can find the external here: http://web.media.mit.edu/~tristan/

Also, a google search or the ever useful maxobjects.com is usually a
much faster and enlightening path to finding answers to these types of
questions.

Hope that helps,
Danny

Thank you. The beat~ is too unreliable, so it’ll have to come down to skill.

Cheers again.
