2wcom has launched the IP-8m Phase-Locked codec for surround sound. The company explains the new eight-channel AoIP codec allows for the transmission of eight digital mono-channels in phase-locked mode such as 8.0, 7.1 or 6.0 and 2.0; 5.1 and 2.0; or 4.0 and 4.0. This means radio stations can provide their listeners live content in both stereo and surround sound quality.
