| 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 |
