We present results of two speech and two audio quality listening tests to compare the two test methods ACR and MUSHRA for different content types. These comparisons have two primary goals: (i) Find relations for transforming test results obtained with one method onto the scale of the other, and (ii) refine audio quality results obtained using the ACR method by using MUSHRA-results for the upper quality regime, where MUSHRA typically shows a sightly better resolution than ACR. The aim is to contribute to the harmonization of speech and audio assessment methods considered meaningful in the light of the convergence between speech and audio coding and transmission.
