PSQM+ Measurement
Description:
Perceptual measurement of speech quality according to ITU-T rec. Includes highly optimized proprietary mapping from raw PSQM values to P. 800 Mean Opinion Score (MOS) scale. Results can be directly compared to subjective listening tests. PSQM+ is optimzed for severe distortions, such as packet loss and time clipping.
