Internal Colloquium Mr. Cable's Low-Fi Reverberator
by Jonathan Abel
A computational structure capable of producing distorted, pitch manipulated reverberation is described. The distortion is virtually free of intermodulation products, making it appropriate for use with material having dense harmonies. The pitch manipulation permits large pitch shifts as well as a kind of scrambling of the frequency axis, including an effect similar to pitch inversion. Sound examples, including distorted room and spring reverberation, two-octave pitch shifting and an inverted guitar, are presented
Wave-Digital Modeling of Hacked Tube Screamer Circuits: Generalizing and Improving the Diode Model
by Kurt James Werner and Vaibhav Nangia
The Tube Screamer, a classic guitar distortion effect pedal, has been studied from several perspectives in the context of virtual analog (VA). This talk will focus on extending a Wave Digital Filter (WDF) model presented by Paiva et al. in "Emulation of Operational Amplifiers and Diodes in Audio Distortion Circuits" (2012). Our extensions focus on the mathematics of (1) a novel, exact, wave-domain diode equation that ameliorates the approximation introduced by Paiva et al. and (2) generalizations to the exact and approximated diode models that allow the simulation of a range of common circuitry "mods" used by guitarists. These extensions highlight the potential for VA simulation of "modded" and "circuit-bent" versions of audio circuitry.
