age author description
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 21:54:50 +0100 Chris Cannam Clumsily cut-n-paste interpolation into pitch tracker as well
Wed, 04 Jul 2012 22:28:46 +0100 Chris Cannam Adjust hypothesis tolerances (i.e. note breaking algorithm) track
Tue, 03 Jul 2012 21:10:56 +0100 Chris Cannam A first crack at turning frequencies into notes track
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
Sun, 01 Jul 2012 11:33:37 +0100 Chris Cannam Reap expired/rejected hypotheses from list; report an estimate as accepted only if the accepting hypothesis has been satisfied already (otherwise a different provisional hypothesis might become satisfied first) track
