Test microphone input, live volume, peak level, clipping and waveform with a private 30-second local recorder. Audio never leaves your device. Use it for everyday work, development, learning, or quick verification.
This tool runs in your browser. Before working with sensitive data, make sure you trust your browser and device environment.
Before a video call or livestream, or after buying a new headset, the most common problems are “they can’t hear me” or “I sound quiet and distorted.” This tool reads your microphone directly in the browser and shows a live level meter, waveform, peak level and clipping count. In seconds you can tell whether the mic picks up sound and whether the level is right, without opening Zoom or Discord and asking someone to listen.
Levels are shown in dBFS (decibels relative to digital full scale): 0 dBFS is the maximum and more negative numbers are quieter. The tool rates the current level automatically. Below −60 dBFS counts as no signal; −60 to −36 is too quiet; −36 to −12 is the good range for speech; −12 to −3 is loud; close to 0 risks clipping. When speaking normally, aim to stay mostly in the good range with occasional peaks below about −6 dBFS for the clearest sound. If the clipping count keeps rising, lower the system input volume or move further from the mic.
If there is no signal at all, check in order: whether the browser has microphone permission (the lock icon left of the address bar); whether the right device is selected, since laptops often have both a built-in and a headset mic; whether your operating system’s privacy settings allow the browser to use the microphone; whether the headset’s hardware mute switch is on; and whether another app has taken exclusive control of the mic. Browsers only allow microphone access over secure HTTPS connections.
To hear how you sound, record up to 30 seconds, play it back straight away or download it as a WebM file. Recording uses the browser’s default audio processing (most browsers enable echo cancellation and noise suppression), so it is close to what others hear on a video call. All audio is processed only on your device and never uploaded to a server.
Normal speech ideally sits in the good range of about −36 to −12 dBFS. Below −36 is too quiet; close to 0 dBFS tends to clip.
Check that microphone permission is granted, the correct input device is selected, your OS privacy settings allow the browser, the headset mute switch is off and no other app is holding the mic.
Your input is too hot. Lower the system microphone volume, turn off automatic gain or move the mic further from your mouth.
No. Recordings of up to 30 seconds stay in browser memory for playback or WebM download and disappear when you close the page.
