Feature request: Spectrogram display

[defensem3ch]

Spectrogram display would be a very neat feature to add. Thanks

I second this request, a rolling spectrogram would be great!

As a rendering technique, you can use a texture in which you draw the row of new pixels, and then render it in two halves, the half after the new pixels would be leftmost, and the half before them would be drawn right of the first half rendered. This way, every frame you only need to transfer the new pixels to the GPU instead of shifting the whole texture in CPU and then uploading the whole thing to the GPU.

I'll be adding this once I'm done with a refactor I'm working on.
Just need to untangle the spaghetti code first.

NICE!
