Measurements

Audio health at a glance

See LUFS-M, LUFS-S, LUFS-I, detected voice level, low-percentile noise floor and ITU BS.1770 true peak in one live view.

Alerts

Find recurring problems

Track voice that is too low or too high, excessive noise, true-peak events, no-audio conditions and stream availability.

Workflow

Designed around real streams

Organize sources in groups, prioritize critical feeds, import or export stream lists and review daily alert history.

Flexible source setup

Browser decoding where possible. FFmpeg where needed.

Configure protocol and decoder selection per stream, including authentication, bearer tokens, custom HTTP headers, RTSP transport and WebRTC ICE servers.
