Fri, 28 Nov 2014 15:35:50 +0000 Chris Cannam Oops, mixed up unit and description fields
Fri, 28 Nov 2014 15:28:07 +0000 Chris Cannam Docs and fixes from plugin tester reports
Fri, 20 Jul 2012 22:12:16 +0100 Chris Cannam Switch from cubic to much simpler & faster parabolic interpolator
Thu, 19 Jul 2012 17:51:57 +0100 Chris Cannam Remove the pitch-tracker; it's now in a separate project (cepstral-pitchtracker)
Thu, 19 Jul 2012 13:09:17 +0100 Chris Cannam Copyright notes etc
Thu, 12 Jul 2012 12:03:58 +0100 Chris Cannam Update to use Vamp SDK 2.4 FFT implementation
Sat, 07 Jul 2012 21:06:37 +0100 Chris Cannam Change peak-to-next-peak ratio to a difference (because difference of peaks in log values don't vary with signal amplification)
Thu, 05 Jul 2012 20:50:56 +0100 Chris Cannam Add rather simplistic cubic interpolation for peak values in a cepstrum output (not yet for pitch tracker). Only gains us 1dp
Mon, 02 Jul 2012 21:37:02 +0100 Chris Cannam Introduce peak-to-second-peak ratio, which looks like a reasonable proxy for harmonic-ness. Use it to ascribe a confidence to estimates in the pitch tracker & rely on that to determine how many similar estimates make a satisfied hypothesis track
Tue, 26 Jun 2012 15:30:12 +0100 Chris Cannam Vertical filtering track
Mon, 25 Jun 2012 15:28:51 +0100 Chris Cannam Experimental tracker (on branch) track
Mon, 25 Jun 2012 14:32:05 +0100 Chris Cannam Copyrights, some cleaning up
Mon, 25 Jun 2012 13:39:46 +0100 Chris Cannam Add total and peak-proportion outputs
Mon, 25 Jun 2012 11:45:33 +0100 Chris Cannam Change "relative to mean" to "relative to RMS", and add peak-to-RMS output. Add a mean-filter history. Remove essentially useless forward-power method (same as forward-magnitude with 2x factor). Refactor a bit
Fri, 22 Jun 2012 23:56:37 +0100 Chris Cannam Attempt a complex inverse transform -- doesn't seem to work well?
Fri, 22 Jun 2012 23:01:00 +0100 Chris Cannam Add choice of cepstrum transform method
Fri, 22 Jun 2012 17:50:03 +0100 Chris Cannam Remove optimistic f0 output (not implemented); add a couple of envelope-related features
Fri, 22 Jun 2012 16:58:55 +0100 Chris Cannam Minor simplification
Fri, 22 Jun 2012 13:38:51 +0100 Chris Cannam First cut at extracting this from its previous home
