That's awesome Pierre!
Charles (Henry) was working on GPU related computation with Pd. Some pretty cool stuff. It would be relevant to see how his work developed so far, and whether it might be useful in this context.
On a side note, I'm taking a studio session with CCRMA folks at the upcoming TEI conference in Barcelona. We will be working with their Satellite kit, which is based on RPI [1].
My goal is to run the Xth Sense [2] biosensor and software directly on the RPI. And after seeing your work, I'm quite confident this is feasible, as the XS is also based on real time audio input.
I'll keep you updated, meanwhile thanks for opening up this perspective Pd/RPI collab!
