Mic and Speaker Sound Test Online
A sound test puts a known signal through one half of your audio chain and measures the response on the other. The microphone side reads peak input level and latency from the live stream, while the speaker side emits a tone, a sweep, or shaped noise so you can confirm playback hardware before a call, stream, or recording session.
Before a call or a recording session you need to know your mic is picking up at the right level and your speakers are playing back clearly. Our Sound Test reads the input signal, plays test tones through the output, and shows both on a live meter so you can confirm the full chain in one check.
Running a Full Sound Check in Four Steps
- Open Device Settings: use the left panel to pick the input and output devices you want to test.
- Run the microphone test: click the mic test button, speak or tap, and watch the live level meter, peak reading, and latency badge.
- Trigger a speaker test: switch to the Speaker tab and pick a 440 Hz tone, a 200 Hz to 8 kHz sweep, white noise, or pink noise.
- Confirm with a real file: open the Playback tab, upload an MP3, WAV, or OGG, and listen through your output device.
