Lesson plan
PEXQ
PEXQ stands for a series of algorithms for the objective measuring of the perceived quality of communication channels and a software suite to use them. In particular the algorithms are * Perceptual Evaluation of Audio Quality (PEAQ) for audio quality of e.g. lossy audio codecs, * Perceptual Evaluation of Video Quality (PEVQ) for video algorithms, * Perceptual Evaluation of Speech Quality (PESQ) for speech transmissions and * Perceptual Evaluation of Data-Download Quality (PEDQ) for data transfers.
