Very brief overview of an audio-visual technique or method.
Using a simple M4L patch (.amxd), one can send out via OSC, the amplitude data, per channel from M4L over ethernet to Touch Designer.
This particular .amxd samples the audio 20 times a second creating almost identical amplitude information that can be filtered and molded in Touch.
We also explore another .amxd that acts as a pitch follower - given that one has a mono-polyphonic sound in M4L, the patch can follow the pitch and reproduce the audio as data, that can control a parameter in Touch.
Much more to explore with this technique .. Send me a PM if interested in discussing this further.
