[. . . ] PEAQ ­ Perceptual Evaluation of Audio Quality OPTICOM's PEAQ (Perceptual Evaluation of Audio Quality) provides accurate and repeatable estimates of audio quality degradation occurring through e. g. [. . . ] Besides the ODG the model outPEAQ in general comprises ear models based puts a complementary quality value ­ the on the fast Fourier transform as well as on a filDistortion Index (DI). The output values of the models are tor like the ODG except for its higher sensitivity based partly on the masked threshold concept towards very low signal qualities. and partly on a comparison of internal representations (also known as comparison in the cochlear domain). In addition, it also yields output values based on a comparison of linear spectra, which are not processed by an ear model.

Copyright © 2005 OPTICOM GmbH ­ www. opticom. de · Output score correlates very well with subjective tests · PEAQ Basic for real-time measurements · PEAQ Advance for more detailed quality analysis PEAQ comes in two versions: PEAQ Basic for real-time measurements and PEAQ Advanced for detailed analysis in non-real-time environments. The main difference of the two models lies in the used ear models and the set of module output values to calculate a final quality score. Typical applications for PEAQ are: Assessment of implementations, perceptual quality line up, online monitoring, equipment or connection status, codec identification, codec development, network planning and aid to subjective assessment. About OPTICOM With PSQM, PESQ and PEAQ, OPTICOM GmbH, the pioneer in perceptual quality testing has been providing three international world-class standards for voice and audio quality measurement since its foundation in 1995. With their new single-sided speech quality measure 3SQMTM, a joint development with partners, the perceptual experts from Germany now presented their fourth ITU standard.
