Hi.
You could try [bonk~] to get beats (as messages) out of your audio signal. [bonk~] is quite sofisticated for your task, but I love it because its smart. You may need to tweak its parameters and/or filter its output ([speedlim] or similar) before you really get what you want.
In maxlib you may find several objects that cab be useful for these purposes, including tempo estimation IIRC.
HTH,

Sorry if this is a newbie question (or dumb) but i'm just starting to use pd, so... :)
In my search for a sensor to detect the heart rate, and after talking to a teacher of mine, he suggested that a very sensitive mic would something to consider as a source for the heart beats.
No comes que question. I have a small mic that i connected to my laptop. I can get the signal in PD. But how can i detect the bpm of a signal that is coming from adc~ object? I'm just touching on the mic to simulate the heart beat, but would be possible to detect some kind of bpm of the signal? If so, what do i have to do? Can you give some links where i can get some more info on what i should do?
Thanks.
