is there a simple way to figure out the bpm of a region (or of a mix) in ardour? i mean something like an average bpm calculator. thanks
Select a single bar of audio, either a one bar long region or select one bar of any region using the range tool. In the menu, Edit > Tempo >, gives you two options, to set the tempo from a selected region or to set the tempo from a selected range. It will also ask you if you want it to set the tempo as global or else add it as a tempo change (new marker).
There are a number of online bpm calculators, play your track and tap the keyboard to the beat. The first one I just found with a quick search was http://www.beatsperminuteonline.com/. Not the one I usually use, I must have lost a bookmark.
I know you asked for a beat calculator, but I've personally had little luck with the accuracy of those. I zoom in on a section that has a strong beat and adjust the master tempo until it visually matches the beat bars. This is actually no harder than it sounds - it just takes a few minutes longer. I always get it right this way, though.
audiodef, see the method leatuspenguin describes above. you will find it as accurate and a lot faster.
