Example 5

This is a pure python example. It is computing a sequence of MFCC with an overlap of 0.5 s and it is creating an animation.

It can be run with:

python main.py

The NumPy sink at the end is just recording all the MFCC outputs as a list of buffers. This list is used to create an animation.

Expected output

Generate graphviz and code
Schedule length = 292
Memory usage 6614 bytes

And when executed you should get an animation looking like this:

The Python main.py contains a line which can be uncommented to record the animation as a .mp4 video.
