Musical control of pipe based on acoustic resonance

[NIME 2011 paper]

[demo page]


We introduce an interactive pipe interface that recognizes touches on tone holes of the pipe by measuring, low-pass filtering, and amplifying the resonances in the pipe without touch sensors. Because this work is based on acoustic principles of woodwind instruments without complex electronics, a simple and durable interface is developed. The measured signals are analyzed to show the resonant sound changes as covering tone holes differently. The audible resonance signal in the pipe interface can be used as a sonic event for musical expression in itself, or also as an input for mapping to generate different sounds.
