ETRI Cross-check report for USAC Common Encoder

Taejin Lee, Seungkwon Beack, Jeongil Seo, Kyeongok Kang

The contribution reported on a cross-check of the JAME USAC Common Encoder for mono items at 24 kb/s. In absolute MUSHRA scores, Reference Quality encoder was better than the Common Encoder which was better than the MPEG reference encoder, all at the 95% level of significance.

The mean score for the Reference Quality Encoder was approximately 10 MUSHRA points higher than the mean score for the Common Encoder. The Common Encoder performed best for speech items.

Jeongook Song, Eunwoo Song, Henney Oh, Hong-Goo Kang

The contribution pools the data from all four cross-check sites. The mean score for the Reference Quality Encoder was xx MUSHRA points higher than the mean score for the Common Encoder. The mean score for the Common Encoder was xx MUSHRA points higher than the mean score for the MPEG Encoder. The Common Encoder performed best for speech items.
