OPUS
OPUS is a highly versatile audio codec. OPUS is used for interactive speech and music transmission over the internet, but is also intended for storage and streaming applications. It is standardised by the Internet Engineering Task Force (IETF). Opus can scale from low bit-rate narrowband speech to very high quality stereo music.
The ESPICO implementations are highly optimised, realising low memory and MHz requirements. Contact ESPICO for specific resource requirements.
