Phoronix: Opus 1.3 Codec Library Nears, New Tools Release

Back in June was the first release candidate of Opus 1.3 (libopus v1.3) with this open-source audio codec allowing to use SILK down to bitrates of about 5kb/s, wideband encoding down to 9kb/s, improved security, improved Ambisonics support, and much more. Libopus 1.3 RC2 is now available along with some tooling updates...

And for those who want to go even lower than 5kb/s or 9kb/s inplaces where such low data rates makes sense (i.e.: for non-internet cases such as digital-over-amateur radio), there's Codec 2 (between 3.2 kb/s and 400 b/s, depending on radio link quality)

The same way which Opus beats the crap out of everything on the internet (against AAC, etc.), Codec2 beats on the ultra-low-bandwidth realm (against AMR, etc.)
