Conference Paper

The Generation of Digital -Electronic Gong- Test Signals

Authors: Travis, Chris

AES Conference: 11th International Conference: Test & Measurement · Paper 11-013 · May 1992

Abstract

In subjective audio assessment, the exponentially decaying sinusoid (-electronic gong-) is one of the most valuable artificial signals. This paper describes the real-time generation of digital electronic gongs that are entirely free of distortion and noise modulation. A linearized fourth-order recursive filter is used. A novel error feedforward technique makes the filter's noise floor perfectly white.
