Subjective Evaluation of High-Quality Audio Coding Systems: Methods and Results in the Two-Channel Case
Experiments completed at the Communications Research Centre in subjective assessment of 2-channel coding systems are described along with the methodologies used in their execution. The discussion centers on acoustic conditions, presentation technologies, choosing audio materials, selecting and training listeners, grading procedures, blind rating, data analysis, and decision-making from experimental outcomes. Key ITU-R test results are presented to characterize the quality of low bit-rate coding systems operating in various configurations.
