Thanks Charlot,
sure, you can listen to the raw output in this post on my research blog: http://bit.ly/hWOml0
It sounds like a far thunder, a very low rumble.
In the video I shared, the lowest frequency you can hear are the ones which most closely resemble the raw output. They are pitchshifted of about only 20Hz to make them more easily audible and give them a denser body. Raw output sits between 20Hz and 40/45Hz. Even though also infra-sounds are integral part of the MMG signal.
cheers, M

Sounds interresting, but do you have some raw microphone output? So we can appreciate the relationship between the muscle *sound* and the output you give through pd.
