The MuBu multi-buffer is a multi-track container for sound description and motion capture data. We are currently developing a set of Max/MSP externals for content based real-time interactive audio processing around the MuBu container.


A set of Max/MSP externals has been freely released at the IRCAM Forum.

Please visit the MuBu Forum page and discussion group.
