Synopsys ARC Audio OPUS Codec
2022-10-13 09:04:56
The Synopsys ARC® OPUS codec is designed for interactive speech and audio transmission over the internet. It is designed by the IETF Codec Working Group and incorporates technology from Skype’s SILK codec and Xiph.Org’s CELT codec.
The OPUS codec is designed to handle a wide range of interactive audio applications, including Voice over IP, video conferencing, in-game chat, and even remote live music performances. It can scale from low bitrate narrowband speech to very high quality stereo music.
The ARC OPUS codec supports ARC EMxD processors. The CELT portion of the codec is specifically optimized for ARC EMxD. SILK codec is implemented for ARC EMxD without target optimization.
