Axtell's Notes: June 28

I re-reorganized the menus today. Now the buttons that only effect the peak graph are in a separate menu that pops up when Show Peaks is pressed. I added the check boxes for constant Q (this doesn't do anything yet) and beats. The beats check box is in the peak graph menu and draws a vertical grey line across the graph wherever BeatFinder finds a beat. It also writes those beats as a wave file. This is done by making a wave that is just a single tone as long as the sample length (for now assumed to be 1024 samples) and a wave of silence of the same length. When BeatFinder finds a beat, it adds the tone and where BeatFinder finds silence, it adds silence. BeatFinder is sort of working, so the BeatWriter is sort of working.

Beats in Shave and a Haircut

This gets almost all the beats except the last one which is a cymbal crash. We think that is why it's missing it because the PeakFinder is missing it too (The last peak should be visible around 2 seconds).

I started trying to look at BeatFinder on longer files and promptly got many OutOfMemoryErrors. I spent the rest of the day trying to increase the max memory for java to no avail. Tayloe is looking at decreasing how much memory everything uses. Hopefully, tomorrow we'll figure out some way to run full length songs again.
