A static, single-page bandwidth calculator for RAVENNA / AES67 / SMPTE ST 2110-30 audio-over-IP networks. Hosted on GitHub Pages at ravennacalc.com.

• Calculate network bandwidth for RAVENNA / AES67 / SMPTE ST 2110-30 audio streams
• Quick presets for common ST 2110-30 channel configurations (2, 4, 8, 16, 64 channels)
• Configurable sample rate (44.1–192 kHz), bit depth (16/24/32-bit), and packet time (125 µs–4 ms)
• Per-stream and total bandwidth results with packet rate, samples per packet, and payload size breakdown
• Multicast bandwidth explanation for professional media network design

samplesPerPacket = round(sampleRate × packetTime)
payloadBytes     = channels × samplesPerPacket × (bitDepth / 8)
packetBytes      = payloadBytes + 54    // 14B Eth + 20B IP + 8B UDP + 12B RTP
bandwidthBps     = packetBytes × 8 × (1 / packetTime)
totalBps         = bandwidthBps × streams
