¿µ¹®³»¿ë¿ä¾à | The demand for the quality evaluation of the audio signals is increased as audio codes are widely used. In order to evaluate the audio quality, subjective quality assessments are necessary, which require much cost and time. Therefore, the methods for objective quality assessment have been developed. ITU-R Rec. BS. 1387-1 is one of the most widely-used standards, which can evaluate the perceptual quality of audio signals objectively. | ||
