IETF Opus codec now ready for testing 2011-02-04 16:36:30 We'd like to announce that the Opus codec is now ready for testing. The bit-stream is now is a "pseudo-freeze", which means that unless a problem is found during testing/review, there are no longer any changes planned. The only exception to this are the SILK-mode FEC and the stereo SILK mode, which should be landing in the next few days. Considering that these are not critical features, we felt like the testing phase could already begin.You can get the source code in two different ways. There is a release tarball at http://jmvalin.ca/opus/opus-0.9.0.tar.gz . You can also extract the source directly from the I-D ( http://www.ietf.org/id/draft-ietf-codec-opus-02.txt ) with the following command:cat draft-ietf-codec-opus-02.txt | grep '^\ \ \ ###' |sed 's/\s\s\s###//' | base64 -d > opus_source.tar.gzNow the Opus codec supports three mores, one of which is identical to CELT 0.11, which was just released (not announced officially yet).It would be nice if the HA community could help test this codec. Opus targets a very wide range of bit-rates, from 6 kb/s narrowband speech up to 510 kb/s stereo music. Perhaps a 64-96 kb/s stereo music test would be interesting to do. Anyone would like to help?
