Audio over IP

Audio over IP (AoIP) is the transmission of multichannel digital audio across standard IP/Ethernet networks using packetized protocols and industry standards.

Audio over IP

Audio over IP (AoIP) replaces traditional point-to-point audio wiring with networked audio transported as IP packets. By leveraging standard Ethernet infrastructure and specialized protocols, AoIP enables flexible routing, centralized management, and multi-channel distribution for broadcast, live sound, installed audio, and studio workflows.

How Audio over IP Works

AoIP systems digitize audio at endpoints, compress or encode it if needed, then encapsulate audio frames into IP packets for transport across switches and routers. Protocols and standards (e.g., Dante, AES67, RAVENNA, RTP) handle timing, synchronization, clocking, and stream discovery. Network features such as QoS, VLANs, multicast, and PTP (Precision Time Protocol) reduce latency and jitter so audio remains locked and deterministic. End devices convert packets back to analog or AES3 outputs at the receiving nodes.

Key Benefits

  • Scalability: add channels and endpoints without re-wiring; support many simultaneous streams.
  • Flexibility: route audio in software, create dynamic signal paths, and integrate remote sources.
  • Cost-efficiency: use commodity Ethernet infrastructure instead of extensive analog/digital snake cabling.
  • Remote management and monitoring: configure, patch, and monitor devices centrally.
  • Redundancy and reliability: network redundancy and stream backup reduce single points of failure.
  • Interoperability: standards like AES67 improve cross-vendor connectivity.

Audience engagement metrics

Audience engagement metrics quantify how viewers respond to digital signage and TV dashboards, tracking measures such as dwell time, views, repeat exposure, interactions and attention estimates. These metrics help signage managers, content producers and IT teams assess content performance, compare placements and make data-driven adjustments to schedules, layouts and creative.

Audio zones

Audio zones are configurable areas within a digital signage network that control which displays and speakers output sound, allowing independent volume, content routing and scheduling per space. They help manage overlapping sound, comply with local policies, and deliver targeted audio experiences across multiple rooms, floors or outdoor areas.
