Fundamentals of Modern Audio Measurement

Authors: Cabot, Richard C.

AES Convention 103 · Paper 4604 · September 1997

Abstract

Fundamental concepts in testing audio equipment are reviewed, beginning with an examination of the various equipment architectures in common use. Several basic analog and digital audio measurements are described. Tradeoffs inherent in the various approaches, the techniques used, and its limitations are discussed. Novel techniques employing multitone signals for fast audio measurements are examined and applications of sampling frequency correction technology to this and convention fat measurements are covered. Synchronous averaging of fits and the ;subsequent noise reduction are demonstrated. The need for simultaneity of digital and analog generation is presented using converter measurements as an example.
