SignalView

SignalView is a stereo sound visualization VST3 plugin. It has a time domain view and a frequency domain view with optional linear or logarithmic display. There is also a sonogram(waterfall) view to see trends in the spectrum. The left and right signals are represented in separate colors which combine to yield white.

SignalView is also available as a LV2 plugin on Linux. To keep the implementation simple there is not a graphical user interface. There are no widgets. Instead the mouse is used to adjust the display. To change the level limits hover over the spectrum and use the scroll wheel on the mouse. To toggle between logarithmic scale and linear scale click the right mouse button. To adjust the frequency range in the linear scale press and hold the left mouse button and move the mouse to the left or right.
