Multi-Touch for Musical Applications

This semester, I have been working with Stefan Sullivan and Scott Dickey on a multi-touch table for musical applications. My goal was to get latency to an absolute minimum, since even small delays can ruin the experience of performance. We achieved 25-30ms latency from touch to audio output with our camera-based system, compared to 50-60ms […]

Voice to NES Music Converter

This is a weekend project idea. Wouldn't it be cool to sing into a mic and have your voice converted to the sweet sound of a 2A03 pulse-width-modulated square wave? "Yes, Matt, that would be cool! But how can it be done!?" I'll tell you. I've got a VST instrument that does my NES synthesis […]

PADsynth in MATLAB

Update, February 15, 2019: Try PADsynth in your browser. PADsynth is a synthesis technique that generates a lush sound with a simple algorithm. The algorithm begins with additive synthesis, where you build a timbre with a sine wave at the fundamental and each overtone. A frequency magnitude plot of this would show several thin spikes. […]


I'm obsessed with getting externalized sounds out of headphones.  It turns out this is darn near impossible.  Using head-related transfer functions to filter the sound and emulate a "transaural" (loudspeaker) source is only the tip of the iceberg...  Read more at binaural audio remixing. I spent the afternoon yesterday trying to reproduce the soundfield created […]
