AudioLink Stream Loudness Monitor, developed by Maycon Vinicius Rodrigues Vicentini, is a Chrome extension that converts a browser tab into a live loudness QA utility for web streams. It monitors loudness and peaks in the tab audio, displays trend history and target badges, and provides a copyable session report for troubleshooting. The tool is aimed at live stream producers and broadcast QA teams who need quick, in-browser verification during broadcasts.

What specific measurements does the monitor provide for broadcast checks?

The tool reports several timed loudness values and peak data; Short-term LUFS (3s), Momentary LUFS (400ms), and Integrated LUFS (BS.1770-style) are available alongside sample peak dBFS with a clearable max-peak hold. Channel health diagnostics present plain-language states such as Stereo, Mono, OUT OF PHASE, and SILENT, and a target badge system labels output as LOW, OK, or HOT.

How does it behave during long sessions and local monitoring?

The meter’s processing runs outside the popup so Integrated LUFS continues across long programs when the UI is hidden, which supports multi-minute measurements. A post-meter Monitor Out fader and mute let engineers change listening level without altering the meter’s reading. The extension also offers an optional 30-second history graph for short trend checks and a visual peak ladder tuned for the -18 to 0 dBFS range.

Can the extension fit into live production workflows and preserve data privacy?

The extension includes a session report generator that copies plain-text audio metrics for inclusion in tickets or chat tools, which helps handoffs between engineers. All analysis runs locally inside the browser and the extension does not record, upload, or transmit audio to external servers. It runs as a Chrome extension on desktop environments, so it integrates where teams already operate their browser-based streaming tools.

A focused browser QA utility best used for quick checks, not reference metering

AudioLink Stream Loudness Monitor is a practical in-browser option for producers and QA teams who need fast verification and shareable session data during streams. It measures sample peaks rather than true peak (dBTP) and is not a certified broadcast meter, so use it as a diagnostic and ticketing aid before committing to calibrated studio-grade measurements.
