Convention Paper

Synthesis and Processing of Audible Notification and Warning Signals

Authors: Moss, Eric P.; Maher, Robert C.

AES Convention 93 · Paper 3354 · October 1992

Abstract

A brief listing of the limitations of audio information transmission and interaction between the audio and visual sensory channels is presented, followed by a description of an automated audible warning signal testbed accounting for those parameters. This station, using a microcomputer and a real-time digital signal processing board, allows real-time processing of two analog input channels, plus synthesis of a third channel. The synthesized channel is composed of -scripts--timed sequences of pure tones, arbitrary waveforms, noise and combinations of the above. The synthesized signals may be panned between two loudspeakers and mixed with the two live analog channels to create the expected ambient sound field in the target application.
