What is RAVENNA?
RAVENNA is an open technology platform for real-time audio over IP. It is built on standard IP protocols and designed for deterministic, low-latency, high-quality audio distribution across networked systems.
RAVENNA aligns with AES67 and SMPTE ST 2110-30, enabling interoperability with other audio networks and broadcast IP workflows. Use the standards comparison for deeper context.
