Convention Paper

Increasing Coverage of International Shortwave Broadcast Through Improved Audio Processing Techniques

Authors: Orban, Robert

AES Convention 86 · Paper 2789 · March 1989

Abstract

This paper describes a system approach to audio processing that considers the audio processor, transmitter, antennas, and receiver. The processor uses several cascaded stages of processing to decrease the peak-to-average ratio of the audio signal, improve its intelligibility, provide band-limiting to CCIR, EBU, and FCC standards, and maintain acceptable subjective quality on both speech and music. The long-term average sideband power achievable with program material is approximately 65% of the power produced by a continuous sinewave at 100% modulation.
