Foam pad controller

Paper: pdf

Abstract
A new instrument is introduced that emphasizes physical processes in both its interface and software. The interface consists of a foam pad that is bent by a performer, naturally providing important tactile and visual feedback. Its design and implementation are described. It is shown that while while work needs to be done to refine the design, these initial efforts encourage further exploration.

Feedback Delay Network Reverberator

Short paper: pdf
Above paper and source code: zadel614project.tar.gz

This is an implementation of a feedback delay network reverberator. It is implemented in STK, but all the required components are included in the source tarball. There is a small graphical interface included which is written in Tcl/Tk.

FFT-1 synthesis

Short paper: pdf
Above paper, source code, and wav examples: zadel605finalproject.tar.gz (3.5mb)

This is a Matlab implementation of inverse FFT synthesis, which synthesizes sound starting from a frequency domain representation. Included are samples comparing the implementation with additive synthesis; there is some amount of timbral distortion present.
