SignalView in action analysing a sine sweep.
SignalView is a LV2 plugin that provides a visual representation of a stereo audio signal. There is a time domain view, frequency domain view and a sonogram.
Precompiled binaries and an LV2 plugin bundle is available for download here
To adjust the level limits use the scroll wheel on the mouse while hovering over the spectrum. To adjust the frequency limit while using the linear scale press the left mouse button and move the mouse left or right. The frequency limit for the logarithmic scale is fixed at the Nyquist frequency. To toggle between logarithmic scale and linear scale click the right mouse button.
The plugin depends on other github projects and therefore requires arguments to the clone command.
git clone --recurse-submodules https://github.com/TimKrause2/SignalViewLV2.git
