Members bieke Posted May 20, 2008 Members Share Posted May 20, 2008 For her thesis, a smart girl (named Sarah) designed conductive felt that is hooked directly into analog signal processing circuits, for filtering sound. By shaping the felt manually, you are also shaping an audio signal. The three signal processing circuits are a chorus effect, a tremolo effect, and a delay/ping pong effect.

Members bieke Posted May 20, 2008 Author Members Share Posted May 20, 2008 The colored felt is attached to the hardware of a delay circuit, which is embedded underneath the white felt. By squeezing and pulling on the colored felt, sound can be sculpted by controlling the number of repeats and the level of feedback happening in the circuit.

Members bieke Posted May 20, 2008 Author Members Share Posted May 20, 2008 squeezing the felt makes its resistance go down, and the number of repeats and level of feedback happening in the delay circuit to go up. Link to comment Share on other sites More sharing options...
Members bieke Posted May 20, 2008 Author Members Share Posted May 20, 2008 pulling the felt does the opposite; its resistance goes way up. the feedback, and hence amplitude simmers down, as does the number of repeats. Link to comment Share on other sites More sharing options...

Members bieke Posted May 20, 2008 Author Members Share Posted May 20, 2008 there's heat-shrink around the wire where it connects to the snap (via soldering), to give it support and prevent the wire from breaking. Link to comment Share on other sites More sharing options...
