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 (8.0, 7.1 or 6.0 and 2.0; 5.1 and 2.0; or 4.0 and 4.0). It’s also possible to switch to 6+2 channels or 4+4 channels.
This means radio stations can provide their listeners live content in both stereo and surround sound quality. The multi-channel codec enables users to feed live contributions into large or international broadcast networks via surround routers.
Suitable for audio broadcast applications like live concerts and studio-to-studio connections, operators can select from audio algorithms, including Dolby Digital (AC-3), Dolby Digital+ (DD+ or E-AC-3), PCM, E-aptX, and AAC.
In addition, the system is compliant with standards such as EBU Tech 3326, AES67, Ravenna, Livewire+ or SMPTE 2110 to ensure compatibility with third-party products. Transmission mechanisms like two internal or external power supplies, error correction mechanisms (Pro-MPEG FEC or SRT), streaming redundancy and backup by alternative audio sources, ensure 24/7 operation.
Users can configure all parameters via a web interface or remotely via SNMP, Ember+ or JSON. Also, a SIP phonebook simplifies intercommunication for remote connections by negotiating protocols and codec algorithms with just one click. The protocols for synchronization NTP, PTPv2, or 1PPS allow a synchronized playout down to 1 µs.
