Your microphone stays in your browser.

RoomTone is designed to show relative room loudness without collecting conversations, student voices, or recordings.

What happens when you click Start

Your browser asks for microphone permission. If you approve, RoomTone reads short waveform snapshots through the Web Audio API, calculates their root mean square loudness, and immediately converts that into a relative level and traffic-light state on your device.

What RoomTone does not do

• It does not create an audio recording.
• It does not upload microphone samples to a server.
• It does not transcribe or identify speech.
• It does not create student profiles or accounts.
• It does not save a history of classroom noise.

Local settings

Activity preset, threshold, sensitivity, recovery time, and alert preference are stored in your browser's local storage so the room can reopen with the same setup. Clearing site data removes these settings.

Stopping access

Pause the monitor or close the page to stop the microphone track. You can revoke access at any time through your browser's site permissions.

Analytics

This temporary pre-domain release has no analytics tag. If analytics are added after launch, they will be limited to product usage and will not include audio, recordings, or microphone samples.
