Dante Bandwidth

Native Dante (unicast/multicast) and AES67 bandwidth & flow-planning calculator

A standard Dante unicast flow can carry up to 4 audio channels to one receiving device.
At 48 kHz / 24-bit, use approximately 1.5 Mbps per audio channel or 6 Mbps for a full 4-channel flow for planning.
With unicast, each receiver gets its own audio stream, so total transmit bandwidth increases as more receivers are added.
With multicast, one audio stream is shared with multiple receivers, so adding receivers does not increase the source transmit bandwidth.
Dante Primary and Secondary networks carry the same traffic on separate network interfaces; calculate utilization for each network independently.
Link Utilization (%) = Estimated Bandwidth ÷ Link Capacity × 100
Higher sample rates, such as 96 kHz or 192 kHz, increase bandwidth proportionally.
Actual bandwidth and flow limits depend on the Dante device, routing, packetization, multicast configuration, and network topology.
Results are intended for AV network design and capacity planning and should be treated as engineering estimates.
