I find, as a drummer, it is easier and more accurate to tap the downbeat of each measure and then subdivide those sections to get the smaller timings. You would only have to tap the song once to do this. I stopped using the audacity and vamp plug-ins because I was unhappy with the placment of the timings.
However If someone could point me to where I could find out how to get audacity to accurately find 16th and 32nd notes, triplets and dotted half notes that would be appreciated.
