This was an initial idea to use an air valve as a mixer, setting in motion a race function between the roundness of the room and the inflation rate (pop time) of the balloon. A microphone would record the burst inside the elastomeric room and deliver a reverb, that might be scaled down to predecit responses of much larger rooms under similar distortions.
This idea is to advance the evolving daxophone. This mutant splits its voice over four channels into separate horn drivers, filtered by silicone vocal tract models. The models are modular so participants can modify the quadripthong.
