Summary:
|
This Corrigendum addresses P.862.2 systematic under-prediction of subjective scores. The under-prediction, 0.8 MOS on average, is due to the audio signals being exposed at an incorrect level to the loudness model. The issue leads to degradations being exaggerated and producing lower scores than expected.
The updated conformance test file for P.862.2 is included in this Corrigendum (suppl23_wb.txt).
