Quality measurement of perceptual audio encoders during design and embedded platform implementation plays a critical role. Perceptual audio codecs, which are lossy in nature, provide tradeoff between quality and complexity based on the application. In this investigation, the PEAQ (Perceptual Evaluation of Audio Quality) is used for measurement of the audio quality and observations are made on its benefits and limitations. Enhancements to improve the performance of PEAQ for quality measurement of perceptual audio codecs are also discussed.
