In this paper, we analyze objective evaluation of MP3 audio with packet loss concealment.
As an objective evaluation for wideband audio,
PEAQ is recommended as ITU-R BS.1387.
However, PEAQ is not designed to evaluate audio with packet losses,
and its accuracy is not sufficient.
So we applied multiple linear regression analysis
using PEAQ's Model Output Variables.
In addition, we improved correlation by taking variance of subband SNR into account,
which may reflects degradation in a specific frequency band.
As a result of cross-validation, mean of correlation was about 0.84. |
