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

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.
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
