Objective Audio Quality Assessment Using a Model of Auditory Perception
Popis výsledku v původním jazyce
A computational auditory model in the objective audio quality assessment system PEMO-Q was replaced by nonlinear auditory model which was recently evaluated in comparison to the psychophysical data (simultaneous and time masking, detection of amplitude modulation etc). The modified system was used to assess the audio quality of various sound samples. Measured objective difference grade (ODG) data were compared with the subjective difference grade (SDG) data. The ODG data were also compared with the ODGdata obtained by means of the original PEMO-Q system. The correlation coefficients between the SDG and the ODG data were calculated. Although the used auditory model can better simulate psychophysical data than auditory model used in the original PEMO-Qsystem, correlation between SDG and ODG data measured in this paper is higher for the original PEMO-Q system.
