CataRT controlled by piezo microphones 1

CataRT controlled by two piezo contact microphones under the corrugated plastic folder, playing a corpus of metallic object sounds.

The piezos' signals are analysed by an attack detector (bonk~ in Max/MSP), and for loudness and brilliance. These two descriptors determine the target position in CataRT's 2D interface to select the segments to play from the corpus, i.e. dull, soft hitting plays in the lower-left corner of the corpus descriptor space, while sharp, hard hitting plays more in the upper-right corner.

The attack detection is not 100% accurate, but since the signal from the piezos is mixed to the audio played by CataRT, the musical interaction still works.
