This study is concerned with objective prediction of perceived audio quality for an intelligent audio system for modeling musical instruments. The study is part of a project to develop an automated tool for sound design. Objective prediction of subjective audio quality ratings by audio experts is an important part of the system. Sound quality is assessed using PEAQ (Perceptual Evaluation of Audio Quality) algorithm, and this greatly reduces the time-consuming efforts involved in listening tests. Tests carried out using a large database of pipe organ sounds, show that the method can be used to quantify the quality of synthesized sounds. This approach provides a basis for the development of a new index for benchmarking sound synthesis techniques.
