Remixing A Song - Accurate BPM detection?

Hi all.

I'm doing this "project" for a local youth center. they're making a Jingle for their Summer Camp.
They chose a song, and I find an accurate instrumental version of it.

What BPM detection tool would you recommend ? I tried http://www.mixmeister.com/ before, but wanted to know if I can find something better.
I also want to sample parts of another song and lay them on top of the instrumental so I need to have accurately stretch and position these parts/songs so it will sound tight.

Basically I thought of detecing the BPMs(with the tool you'll kindly recommend ) and then snapping the 1st Audio Transient of each song/part to the start of bar 1, this would resolve in pretty accurate "remixing" right?


Thx in advance, ZBBZ.

the one you looked at is the best one I know of, and it doesn't do well for a song that changes tempos, even slightly, it averages the tempo of the song.

the only thing I know of that will give you accurate tempo in software is to use audio snap to find the transients and then create a click track from the transients like mike said.

agree with hart that is how I do this also....

Unless the tempo is dead-even throughout, aligning only the first measure isn't going to cut it, and even then you're going to have to be extremely precise aligning the first few beats to still have things aligned later in the timeline.

Once you get the first beat aligned to the timeline by sliding the clip, if it's not at 1:01:000, I recommend you use Set Measure/Beat At Now to pin that beat to its transient. Then count out 8 or 16 measures, and do the same with a beat further into the piece. If the transient marker(s) you use are right on, and the tempo is solid, you may find that this aligns the whole piece. In some cases, you may also find that the calculated tempo is within a couple hundredths of some nice even whole number like 120BPM, in which case you might want to undo your tempo changes, and just manually set the project to that even tempo, which is probably what was used originally.

If, on the other hand, you go out to the last beat and find that it's close but not quite right, you'll want to take note of what beat the transient should have fallen on, undo your previous Set, and Set that last beat. That will give you a good average tempo. If you then find that intermediate beats are not aligned, then tempo is not steady, and you'll need to Set additional points as necessary to tighten it up.

When you're all done, if the first beat was not at 1:01:000, you'll want to manually set the first tempo in the project to match the average tempo.
