Audio Live

Audio Router for Live Multistream IP Audio Processing

Audio Live is designed for modern, real-time IP workflows. It offers 2,048 channel processing capability for SMPTE ST 2110-30/SMPTE ST 2110-31/RFC3190/AES67 audio streams. It can be configured as an asymmetric router rather than a traditional square router, offering far greater flexibility. Input audio streams should be synchronous, but when this is not possible, Audio Live offers the ability to synchronize up to 16 asynchronous inputs streams.  

FEATURES

  • Flexible asymmetric router
  • Independent input and output routing configurations
  • 11 different routing configurations
  • Stream and channel swapping
  • 2048 x 2048 audio channel routing
  • Certified by Grass Valley engineering
  • Hardware and software supported by Grass Valley

Input Streams
  • Synchronous SMPTE ST 2110-30/SMPTE ST 2110-31/AES67/RFC3190 (PTP timestamps required in extended headers, RTP & PTP timestamps must be locked)
  • Supports various packet times per stream (provided the packet size is within 1500 MTU)
  • Up to 16 asynchronous streams can be synchronized to the reference stream
  • Packet redundancy (-7 style)
  • Packet reordering
  • Streams can have independent packet timing of 125 µs, 250 µs, 500 µs, 1 ms & 4 ms (nominated input reference stream should be ≤ 1 ms)
