Wed, 14 Nov 2018 14:17:06 +0000 Chris Cannam Various tweaks & fixes to log-scale handling in spectrum. We can't easily preserve the nice behaviour where peaks stay in place as fft size changes, without potentially losing a bit of low-frequency information spectrogramparam
Tue, 13 Nov 2018 14:06:48 +0000 Chris Cannam Make "zoom to region" work sensibly for slice/spectrum layers; ensure that min/max bin are remapped properly when changing fft size spectrogramparam
Mon, 12 Nov 2018 14:48:42 +0000 Chris Cannam Small speedups spectrogramparam
Mon, 12 Nov 2018 11:34:34 +0000 Chris Cannam Use log-frequency rather than log-bin for calculating x coord in spectrum. This has the advantage that frequency positions don't move when we change the window size or oversampling ratio, but it does give us an unhelpfully large amount of space for very low frequencies - to be considered spectrogramparam
Thu, 08 Nov 2018 11:12:04 +0000 Chris Cannam Fix "colour" rendering for spectrum (now resembles a filled "line" mode rather than a filled "block" mode) spectrogramparam
Wed, 07 Nov 2018 15:59:10 +0000 Chris Cannam Switch spectrum to antialiased drawing with considerable speedup for the dense areas; take horizontal scale height into account when rendering slice layer height spectrogramparam
Wed, 07 Nov 2018 11:37:51 +0000 Chris Cannam Add oversampling option to spectrum as well spectrogramparam
