Features & Capabilities

Real-time browser loudness meter with LUFS, LRA and ITU true-peak monitoring.

Measure the audio delivered by a browser tab, window, or shared screen in a focused, broadcast-inspired meter.

Luftr Loudness Meter displays:

Momentary, Short-term, and Integrated loudness in LUFS
Loudness Range in LU
true peak and maximum true peak in dBTP
left/right channel level meters
zoomable history with target and tolerance band
EBU R 128 and ATSC A/85 presets
clearly labelled streaming, podcast, and music reference targets
light and Night View interfaces
a locally generated Export Card

For standards-oriented programme measurement, select Session and leave Dialogue Focus off. Rolling integration windows are monitoring conveniences. Dialogue Focus is an experimental local speech gate and is not a standards-compliant programme-loudness mode.

Privacy is simple: audio is analysed locally and is not recorded or uploaded. The extension has no telemetry, analytics, advertising, accounts, or cloud service. Only user preferences are stored locally.

Luftr Loudness Meter measures the audio supplied by the browser capture path. Browser or operating-system mixing and resampling can affect the signal. The extension is a standards-oriented production aid, not a certified laboratory instrument.

Is Luftr Loudness Meter Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Luftr Loudness Meter does not require any sensitive permissions.

Risk impact analysis details

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Luftr Loudness Meter is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
