Minim beat detection inconsistency

velvetkevorkian

I'm doing some very basic beat detection with Minim but I'm finding the results to be somewhat erratic. Each time I analyse the same file with the same settings I get a different result. I would have expected that this should give the same result each time, given the same input — is that not the case?

Thanks.

If the BeatDetection object does not see every single buffer of audio from the file it will be a little bit different every time, I think. If you are analyzing the song with something like beat.detect(song.mix) in your draw(), then which buffers the detection algorithm sees will depend on framerate of the sketch.

OK, that makes sense, thanks. For it to be 100% consistent then you would have to set the buffer length to sample rate/frame rate, I guess.
