Networked Audio & Ethernet AVB | XMOS

NETWORKED AUDIO


  • Ethernet AVB
  • time sensitive networks

Business benefits are driving the increasing move to Ethernet-based network audio. Networked audio installations appear in many applications from public address systems and live broadcasting to the automotive and commercial worlds. All these sectors demand the high-fidelity, low latency, robust delivery which can be achieved with xCORE

There are many open and proprietary network audio standards. Each brings their own benefit but with no clear leader, the decision of which to adopt can be difficult. And then you have to integrate your chosen networked audio standard together with your product specific features.

xCORE solutions are agnostic enabling you to support your chosen standard today whilst future proofing for tomorrow. xCORE solutions provide deterministic multicore performance, ensuring each product feature performs as you need it to. The result is a high performance, competitive and differentiated networked audio product.

ETHERNET AVB and AVnu

The AVB standard was developed under the guidance of the AVnu Alliance.
