Note that this draft is not meant to include all the details of the tests. For that, you should refer to the original results documents that are cited for each test. All of them are available on the net except for the most recent test: "Voice Quality Characterization of IETF Opus Codec" that will be presented by Anssi Ramo (from Nokia) at Interspeech 2011. However, he was kind enough to provide me with a copy and gave me permission to redistribute it to working group members upon request. > Also, in order to plan further listening-only tests, an overview of missing > test cases is missing. > > Do you plan to provide anything in this respect in a later update of the > document?

As stated in the conclusion, we believe that the combination of all tests demonstrates that Opus is better than the codecs it needs to beat. Feel free to conduct any test you deem useful if you disagree with parts of the conclusions. > Do you plan to have an additional informal IETF RFC with the > characterization results? This would make sense but it requires changes in > the charter... At this point, this draft is not meant to ever become an RFC. It is only meant for discussion (friendlier than a lengthy post on the mailing list). Cheers, Jean-Marc
