Subjective Quality Evaluation of Audio Streaming Applications on Absolute and Paired Rating Scales

Document Thumbnail

In the context of the development of a parametric model for the quality assessment of audiovisual IP-based multimedia applications, audio tests have been carried out. The test method used for the subjective audio tests was aligned to the method used for video tests. Hence, the Absolute Category Ranking (ACR) method was applied. To prove the usability of ACR tests for this purpose MUSHRA and ACR were applied in parallel listening tests. The MPEG audio codecs AAC, HE-AAC, MP2 and MP3 at different bitrates and different packet loss conditions were evaluated. The test results show that the ACR method also reveals the quality differences for higher qualities, even though MUSHRA has superior resolution.
