Frequently asked questions
Why is my microphone not working in the browser?
Common causes are blocked permission, the wrong input device, or another app using the mic. Allow access in the browser and select the correct device in system settings.
What should the level look like when I speak?
A healthy signal moves well into the middle or upper part of the meter without hitting the very top. If it stays flat, move closer or raise the input volume in your system settings.
Why do I hear an echo when I play back?
The microphone is probably picking up your speakers. Use headphones during playback so the sound does not feed back into the mic.
