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
