<p>Method and apparatus for predicting the quality of an audio signal after transmission through a communication system (21), the method using a reference signal (11) corresponding to an input signal to the communication system, and a processed signal (12) corresponding to an output signal from said communication system. The signals are segmented into blocks, and e.g. three spectral parameters are calculated for each block in the processed and in the reference signal. Thereafter, the quality of the audio signal is predicted from the distortion between these parameters.</p> |
