annotate layer/TimeValueLayer.h @ 42:1bdf285c4eac

* Add "Export Audio File" option * Make note layer align in frequency with any spectrogram layer on the same view (if it's set to frequency mode) * Start to implement mouse editing for ranges of points by dragging the selection * First scrappy attempt at a vertical scale for time value layer
