What the numbers mean
RMS is the average loudness and peak is the loudest instant, both shown in dBFS (0 is the most it can hold). Sound that reaches that maximum counts as clipping.
- Echo cancellation, noise suppression and auto gain are the browser's processing and may differ from your settings in Discord or a game.

Common questions
Is my mic audio sent to a server?
No. Sound, recordings and device names are only used in this browser and are not saved.
The bar doesn't move at all.
Permission may be blocked, the input volume may be 0 or another device may be selected. Go through the checks above in order.
What dBFS number is good?
There's no single right number. If the bar moves when you talk and clipping doesn't show, you're fine.
Does it work with a Bluetooth headset mic?
If Windows lists it as an input device, you can pick it in the list and test it.
I want to check my speakers or headset too.
The speaker test plays the left and right sides separately.
