Abstract:

Audio feedback in its pure form is notoriously difficult to control, yet at the same time it has a lot to offer as one of the simplest methods of creating sound in an expressive, tangible way. In an effort to provide a simple, easily replicable feedback instrument, I’m proposing the Feedback Ocarina - a simple device, combining a 3d-printed variable frequency Helmholtz resonator with an inexpensive microphone cartridge. By opening and closing finger holes, it’s possible to control the feedback frequency, much like with a standard, acoustic ocarina.
