age author description
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
Thu, 18 Oct 2018 13:21:56 +0100 Chris Cannam Add mechanism for saving/loading colour maps by name/id rather than by numerical index, for future compatibility when adding to or changing the supported colour maps. Add two new colour maps (and one old one). Write out backward-compatible numerical indices for use when reloading in older versions. Also add a mechanism to invert the colour map, though I don't think it turns out useful enough to include in the UI.
Tue, 08 May 2018 14:27:54 +0100 Chris Cannam Hack to ensure vertical scale lines are in the right place in pixel-doubling rendering
Thu, 03 May 2018 15:15:15 +0100 Chris Cannam Provide linear horizontal scale in spectrum as well as log; fix bin positioning and colour scale property box updating; ensure proper background colour and visibility of peak lines horizontal-scale
Thu, 01 Mar 2018 18:02:22 +0000 Chris Cannam Untabify
Tue, 12 Dec 2017 11:19:15 +0000 Chris Cannam This was new in GCC 7
Thu, 07 Dec 2017 13:31:32 +0000 Chris Cannam Add fallthrough attribute
Tue, 07 Mar 2017 18:54:15 +0000 Chris Cannam Make some corrections to crosshair (measure cursor) positioning and feature descriptions. Needs review.
