Microphone Volume Test
Check your microphone input volume online. Test whether your mic is too quiet, too loud, or causing clipping distortion with an accurate, real-time decibel (dBFS) level meter.

माइक्रोफ़ोन की आवाज़, क्वालिटी और सिग्नल जांचने के मुख्य बिंदु:
Optimal Conversational Volume
Speak in a normal conversational tone. The green section of the meter indicates your audio is clear and audible.
सामान्य आवाज़ में बोलें। मीटर जब हरे रंग (-24 से -12 dBFS) में रहे तो इसका मतलब आवाज़ बिल्कुल साफ़ और सही है।
Listen to 5s Sample Playback
Numbers on a meter are helpful, but listening to your own recording through headphones tells you if robotic artifacts or hissing exist.
हेडफ़ोन लगाकर अपनी रिकॉर्ड की हुई आवाज़ सुनें। इससे पता चलेगा कि आवाज़ में खरखराहट या बैकग्राउंड का शोर तो नहीं है।
Prevent Breath Puff Distortions
Keep the microphone 4 to 6 inches away and angled slightly off-axis to avoid loud popping noises on P and B sounds.
माइक को मुंह से 10–15 सेमी दूर रखें जिससे सांस लेने या भारी अक्षरों (प, ब) के उच्चारण से आवाज़ फटे नहीं।

navigator.mediaDevices.getUserMedia().Understanding Digital Decibels (dBFS)
In computer audio, volume is measured in dBFS (decibels relative to Full Scale). Unlike real-world sound pressure level (dB SPL), 0 dBFS represents the maximum possible digital value before distortion.
• 0 dBFS: Absolute digital ceiling. Exceeding this causes clipping (harsh square-wave distortion).
• -6 to -12 dBFS: Loud speech / emphatic laughing zone.
• -18 to -24 dBFS: The ideal target zone for conversational speech.
• -35 to -50 dBFS: Low volume. Callers will struggle to hear you or turn their speakers up high.
• Below -55 dBFS: Ambient room noise floor / near silence.
Why Is My Microphone Too Quiet?
If your speech struggles to push the vertical meter past -40 dBFS, check these common bottlenecks:
| Potential Bottleneck | What to Check | Correction Action |
|---|---|---|
| OS Input Volume Slider | Windows / Mac sound settings | Slide volume control up to 85%–90%. |
| Hardware Gain Potentiometer | Physical knob on USB mic body | Turn gain clockwise until -18 dBFS is reached. |
| Physical Distance | Distance from mouth to mic | Move closer (ideal distance is 4–6 inches). |
| Microphone Orientation | Cardioid front vs rear orientation | Turn microphone so the front faces your lips. |
| Third-Party App Attenuation | Zoom / Discord auto-gain | Disable automatic volume adjustments in app settings. |
Frequently Asked Questions
Q.What should my volume meter read when I talk?
Aim for a consistent bounce between -24 dBFS and -12 dBFS. This leaves healthy digital headroom so sudden loud words do not clip.
Q.Can low volume be caused by my browser?
Yes. If your browser does not have direct exclusive access or applies its own AGC constraints, signal volume can be suppressed. Testing across Chrome and Safari helps isolate the cause.
