Abstract

Method and processing system for establishing the impact of time response distortion of an input signal which is applied to an audio transmission system (10) having an input and an output. A processor (11) is connected to the audio transmission system (10) for receiving the input signal (X(t)) and the output signal (Y(t)), and the processor (11) is arranged for outputting a time response degradation impact quality score. The processor (11) executes preprocessing of the input signal (X(t)) and output signal (Y(t)) to obtain pitch power densities (PPX(f)n, PPY(f)n) comprising pitch power density values for cells in the frequency (f) and time (n) domain, calculating a pitch power ratio function (PPR(f)n) of the pitch power densities for each cell, and determining a time response distortion quality score (MOSTD) indicative of the transmission quality of the system (10) from the pitch power ratio function (PPR(f)n).
