Three years ago Opus got rated higher than HE-AAC and Vorbis in a 64 kb/s listening test. Now, the results of the recent 96 kb/s listening test are in and Opus got the best ratings, ahead of AAC-LC and Vorbis. Also interesting, Opus at 96 kb/s sounded better than MP3 at 128 kb/s.

I just got back from the 135th AES convention, where Koen Vos and I presented two papers on voice and music coding in Opus.

Also of interest at the convention was the Fraunhofer codec booth. It appears that Opus is now causing them some concerns, which is a good sign. And while we're on that topic, the answer is yes :-)
