sympathetic bite is an interactive system for enhancing the everyday act of eating chips. As the eater-performer chews and swallows some crunchy crisps, this mastication companion adds some savory sounds to spice things up. sympathetic bite mimics the gourmand’s chewing dynamism. Pops and crackles are amplified to generate an appetizing soundscape; a subtle nibble will result in mild sonic events, while a vigorous bite will lead to zesty rhythms. This human-machine snack duet, therefore, fosters thorough mastication and playful eating.

How does it work?

The sympathetic bite system utilizes a Daisy microcontroller that processes sound input from a microphone. Input exceeding an amplitude threshold is recorded, and a granulator generates grains from this material with parameters that adapt to analyses of the input signal. Meanwhile, the Teensy receives data from an accelerometer placed beneath the eater's chin and transmits it to the Daisy through UART communication. This data modulates the reverb of the generated grains. Knobs on the board allow for adjustments to the input gain and trigger threshold for recording. When the sound input exceeds the adjustable threshold, an LED on the board illuminates, indicating proper calibration of the system.
