Getting and Using Vamp Plugins / Quantization of onset detection

« on: July 17, 2008, 11:58:19 »

I just started using the "Note onset detector: Note onsets" plugin.  This is a very powerful application, and kudos to its authors.  When I export the results as text files to examine in another programming environment, I notice that they're all quantized.  Although it looks like there are several significant digits to each time instant, they seem to move by increments of 25 milliseconds, which is perceptually significant.  Inverted to beats per minute, it's 1.5 bpm.  Is this a consequence of the fft window size, or a feature of the plugin?  Can I get higher resolution somehow?

Thanks,

Mitch
