BPM in Pro Tools

I hate to ask this, I should there an easy way in Pro Tools, Beat Detective, whatever, to throw in a drum loop and for Pro Tools to tell you what BPM it is?

Thanks...I feel dumb for asking this, I don't do loops much...humbled. I have a ton of loops to audito, many of which don't have the BPM labeled and I don't want to spend all day counting beats and estimating BPMs.

Thanks for any help!

Try this:

There is a link "Tempo Matching" or "Identify Beat" under "Pro Tools Tips and Techniques".

Hope this helps,

If I recall right, you can also use Ableton/-Lite; insert Ableton RTAS, drag files to a track, and the edit window will show original tempo of the loop... I think...

If the loops are already cut (or if you can verify a sample-accurate length), you can derive the BPM from the loop length.

Calculate by measuring the loop in samples:

number of beats sample rate 60 sec
______________ x _______ x ______ = beats/min
length of loop (samples) 1 sec min


2 bar loop (8 beats), 200,000 samples, 44100

8/100000 x 44100 x 60 = 105.84 BPM

This is the MOST ACCURATE way of measuring tempos.

Physicists & chemists will recognize "factor label" method. And I was told that my Bachelor's degree would be useless in the music industry...

theres that audiosuite plugin which comes with PT. time shifter ? ( sorry cant remember the name ) . you just select the desired loop, type in the beat measure ( f.ex 4/4 ) and it tells you the exact tempo. then you can change the session tempo and your done ...

takes ~ 5 secs.

Yeah, what toolskid said. But to give a little more detail:

a) Put Pro Tools into grid mode.
b) drag your loop onto a track. The start of the loop should be right on a bar line.
c) make sure the loop is selected, hit apple key+i ("Identify beat")
d) in the dialog that pops up, set the right bar/beat numbers (i.e. if you have a 2-bar loop, set the end of the loop to be at bar 3 beat 1)
e) you can now see the bpm in the extended transport bar.

repeat as necessary.
