2019-06-28 Chris Cannam Further layer updates for ById by-id
2018-11-26 Chris Cannam Use override throughout fix-static-analysis
2018-11-15 Chris Cannam Retain consistent min freq (rather than min bin no) when changing fft parameters in spectrum; scale ffts by window size rather than fft size in case of oversampling, to avoid fading out because of scale factor including zero padding
2018-11-14 Chris Cannam Highlight the current peak line in the spectrum (when shown); also a fix to the crosshair labelling spectrogramparam
2018-11-12 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
2018-11-07 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
2018-11-07 Chris Cannam Add oversampling option to spectrum as well spectrogramparam
2018-10-18 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.
2018-05-03 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
2018-05-01 Chris Cannam Branch toward adding horizontal numerical scales to things horizontal-scale
2018-03-01 Chris Cannam Untabify
2017-02-22 Chris Cannam Overrides
2017-02-07 Chris Cannam Some work to make spectrum layers (and slice layers generally) zoomable in the frequency axis. Also fixes a number of view id mixups in SliceLayer which broke offset calculations for the x axis scale.
2017-01-26 Chris Cannam Fix silly definition that prevented spectrum scale from appearing
2015-03-17 Chris Cannam Many fixes for the previous stuff osx-retina
2015-03-17 Chris Cannam Start trying to introduce LayerGeometryProvider as proxyable interface for View methods that the Layer wants to use osx-retina
2015-03-09 Chris Cannam Working through the float/double and int/sv_frame_t fixes cxx11
2014-06-17 Chris Cannam Remove size_t's and fix warnings in layer/ warnfix_no_size_t
2012-01-30 Chris Cannam Give a dedicated key to toggling the centre line, and move it out of the overlay level setting -- reducing number of overlay levels to 3. Introduce two distinct vertical scale types (so that we can hide the spectrogram colour scale part easily)
2011-07-06 mathieub Extends the audio feedback of the piano scale to the Spectrum layer (horizontal piano keyboard). sonification
