Signal Processing Techniques for Digital Audio Effects Group Study

Catalog description

Techniques for dynamic range control, equalization and filtering, delay effects and reverberation, digital emulation of analog processors, and implementation of time-varying effects. Single-band and multiband compressors, limiters, noise gates, de-essers; parametric, shelf, and resonant equalizers, wah-wah, phasor, and envelope-following filters, filter banks; echo, chorus, flange, tape delay; room acoustics analysis and comb, allpass, and feedback delay network reverberators. Students implement common digital audio effects in real-time audio plugins, and work on their own projects. Prerequisites: the Discrete Fourier Transform, z-Transform, and difference equations at the level of 320A; modest C programming and Python or Matlab experience. Recommended: EE 264; audio effects in mixing and mastering at the level of 192.
