The Relationship between Selected Artifacts and Basic Audio Quality in Perceptual Audio Codecs

Up to this point, perceptual audio codecs have been evaluated according to ITU-R standards such as BS.1116-1 and BS.1534-1. The majority of these tests tend to measure the performance of audio codecs using only one perceptual attribute, namely the basic audio quality. This approach, although effective in terms of the assessment of the overall performance of codecs, does not provide any further information about the perceptual importance of different artefacts inherent to low-bit rate audio coding. Therefore in this study an alternative style of listening test was performed, investigating not only basic audio quality but also the perceptual significance of selected audio artefacts. The choice of the artefacts included in this investigation was inspired by the CD-ROM published by the AES Technical Committee on Audio Coding entitled “Perceptual Audio Coders: What to Listen For”.
