Hello, According to the specs <http://www.opus-codec.org/> Opus supports different sampling rates from 8 kHz to 48 kHz, it would be great to support Opus narrowband (8 kHz) to give developers a chance to use it in "small bandwidth available" scenario for interoperability with existing VoIP solutions. Use case: mobile device makes call to some Media Gateway which transcodes 8 kHz Opus to G.711 or G.729 and then sends it to some SIP endpoint. We avoid problems for the last mile connection since Opus is much better than G.711 in terms of PLC and bandwidth consumption. As I understand Opus was only discussed as a solution for wideband audio so far… Best Regards, Alexey
