Personal Computer Audio Quality Measurements

This document focuses on the measurement of audio quality in a PC environment. Each specification listed has a definition and an example measurement technique. Both electrical and acoustic specifications are discussed. Also included is a detailed description of example test setups to measure each specification. Appendices are used to define the signal paths for measurement, decibel definitions, and weighting filters. Quality levels for some of these measurements are suggested in Microsoft's PC 97, PC '98, PC 99, Intel's AC 97, and in the MPC3 specification.
