At any point in the the process, matrix data can be tapped to produce an audio signal. Analyzing video is very much like analyzing audio. For example, using envelope following and spectral analysis. Here are examples.

5. Whispering Heights (in Max/MSP examples/jitter-examples/3rd-party/image-to-spectral-filter/whispering_heights.maxpat)

Similar to above but uses video to create a moving spectral filter.

6. Wolframatic.maxpat  (in Max/MSP examples/jitter-examples/other/Wolframatic/)

Fractal generator also generates audio.

Pd signal streaming objects

Use streamout~ and streamin~ to stream audio over a local network

The ‘help file’ for streamout~ has an example. Change ‘localhost’ in the connect message to the local IP address of the target.
