EVS Codec for Synopsys ARC Processors

The Enhanced Voice Services (EVS) codec for Synopsys ARC® Processors is a super-wideband speech audio coding standard. The original specification was developed by 3GPP and described in 3GPP TS 26.441. EVS is the mandatory audio codec for super-wideband transmissions via VoLTE. This codec offers up to 20 kHz audio bandwidth, with high robustness to delay jitter and packet losses due to its channel aware coding and improved packet loss concealment. The application areas for this codec cover improved telephony and teleconferencing, audiovisual conferencing services, and cellular streaming audio.
