Frequently asked questions
How do I avoid echo while monitoring?
Use headphones and optionally increase monitor delay. Speakers will feed your voice back into the mic.
What is room noise in diagnostics?
First measure silence, then voice — this estimates how well speech stands out from background noise.
Why can't the browser see my microphone?
Check that no other app is using the mic, the browser has permission in the site settings, and the device isn't muted at OS level — then reload the page.
Is my recording uploaded anywhere?
No. Recording and playback are local; files are stored in your browser and never leave your device.
