Mic and Speaker Test: Complete Sound Check
A guided multi-step diagnostic that tests your microphone, background noise levels, voice replay, left and right speaker channels, and stereo phase. Returns a composite score and direct recommendations.
Before you start
A guided diagnostic covering your microphone, noise floor, a 5-second voice replay, and stereo output. Produces a composite score with a plain-language diagnosis.
Your browser will ask for microphone access. Every step can be skipped, and speaker tests still run without a mic.
What is tested
- Microphone Input
- Permission check, RMS level measurement, and clipping detection.
- Noise Floor
- 2-second silence measurement. Classifies as quiet / moderate / loud.
- Voice Replay
- Records a 5-second sample and plays it straight back, so you hear what other people hear. Recorded in-browser and discarded when you leave the step.
- Left and Right Channels
- Plays a 1 kHz tone to each speaker channel independently. User confirms what they hear.
- Stereo Phase
- Checks that both channels are playing correctly together.
- Composite Score
- Weighted average of all sub-tests. Mic and speaker channels are weighted highest.
How scoring works
| Score | Label | What it means |
|---|---|---|
| 85–100 | Excellent | All core tests passed with no issues. |
| 65–84 | Good with notes | Minor warnings — worth investigating. |
| 40–64 | Needs attention | One or more tests failed or warned. |
| 0–39 | Multiple issues found | Several tests failed — see recommendations. |
Quick answers
Frequently asked questions
What is the Complete Audio Check?
The Complete Audio Check is a guided mic and speaker test that examines the main input and output parts of your audio setup in one session. It is useful when you know something sounds wrong but do not yet know whether the microphone, speakers, headphones, settings, or connection is responsible.
What does the mic and speaker test include?
It checks microphone permission and input level, clipping, background noise, a five-second voice replay, left and right output channels, and stereo phase. At the end, AudioSolver combines the results into a score and shows recommendations for the checks that need attention.
How do I run the Complete Audio Check?
Choose the microphone and output devices you want to test, begin at a low listening volume, and follow each step in order. Speak normally for the microphone checks, stay quiet during the noise measurement, listen to the voice replay, and confirm which speaker cues you hear.
How long does the Complete Audio Check take?
Most people can finish it in a few minutes. The measured microphone, noise, and voice replay steps are short, while the total time depends mainly on how quickly you confirm the left, right, and phase playback results.
Can I run the Complete Audio Check on a phone?
Yes, it works in current iPhone and Android browsers that support microphone access and browser audio playback. Disconnect Bluetooth devices if you want to test the phone’s built-in microphone or speakers, and remember that some mobile systems choose the active audio device automatically.
Is the Complete Audio Check private?
Yes. Audio measurements and the temporary voice replay are processed locally in your browser. AudioSolver does not upload the microphone stream or voice sample to its servers, and the temporary recording is discarded when you leave the relevant step or page.
How is the audio check score calculated?
The score is a weighted summary of the completed checks, with core microphone and speaker-channel results carrying the most weight. A high score means the tested signals behaved as expected; a lower score points you toward the specific failed or warning results rather than proving that hardware is broken.
Why does the test ask me what I heard?
A browser can play a left, right, or phase signal, but it cannot reliably know which physical speaker reached your ears. Your confirmation lets the test identify reversed channels, a silent side, or an unexpected phase result without requesting unnecessary access to your surroundings.
What should I do if the Complete Audio Check finds a problem?
Open the recommended focused test or troubleshooting guide, then repeat the affected check after changing one thing at a time, such as the selected device, permission, cable, port, Bluetooth connection, gain, or balance setting. Consistent failure across devices may indicate a hardware problem.
