Jan 4, 2013 at 15:48 comment added Bruce Zenone Not sure what you mean by "onset". If you mean the start of the music signal, I would say this is really a time domain problem and doesn't require FFT information. I would write an energy detection algorithm and look for energy above a certain threshold.
Jan 3, 2013 at 17:29 comment added Advecticity I'll be taking the derivative in the time direction (if that is a correct way of saying it) for onset detection. There's a couple of ways to get around the vertical lines (such as setting them to 0, or blurring) but they are all suboptimal to removing the lines to begin with, if doable.
