Simple python tool for creating animated spectrograms
It would be good to make this tool more general by allowing the user to choose from a collection of different DSP transforms
Pyaudio blocks on it's stream.write() calls, playing the tone, but preventing further computation from occurring, leading to a choppy sound. Ideally we would continue computing while the chord finishes, potentially blocking on a second call to stream.write() while the other finishes.
The animated spectrogram in particular looks like it was built with a potato. Hope to be working toward a 3d colored plot a la https://www.youtube.com/watch?v=vvr9AMWEU-c. Looking into python-opengl tools https://glumpy.github.io/ and http://vispy.org/
many of these can be inferred from the signal and were just kludged in to get it running.
Need to implement pause, speed controls.
Like to have visual region / transform window / spectrogram history / zoom etc. controls.
