Render windowed waveform as video/animation #96

This tool is great for static waveform images. It would be great, though, if it could be extended to generate animation by creating a series of images where the waveform is windows and would scroll across the time as it is being often done in many visualizers.

I guess this could be done in post-processing step using video editors, but I think it would make sense to include such a feature here.

Hi @faroit, adding this feature is not something we currently have planned, and I think it may well be better implemented as a separate tool. Have you tried New York Public Radio's Audiogram project? I wonder if this could be a closer starting point for what you need.
