H, i your project catched my attention because I was wondering lately how one could record interesting human body sounds. Could you give me some details about you microphone technique for this project?
Thanks a lot.

Thanks for the feedback Richie,
There's a bunch of processing chains which, overall, include these DSP objects:
- pitch shifting
- biquad bandpass filtering + reverb + pshift (uses RjLib beequad~ )
- a rt granulator
- a granular delay (uses Soundhack [+bubbler~])
- two delays (one of them uses Soundhack [+pitchdelay~])
- a rt time-stretcher
- a cos pan
However, the most interesting aspect to me is not much about the DSP techniques, but focuses on the mapping of the kinetic energy to control data.
It's an interesting study, which requires further exploration.
Part of the final research outcome is to release the Pd framework and the related lib I'm developing.
There's still much to do though!
I love it Marco, Are you granulating the muscle sounds? I hear reverb and
delay... Just wondering about your DSP techniques.
Beautiful and novel work. Thank you.
