Audio & Microphone — Tests & Tools

Test your microphone in the browser — speak and watch the live waveform and dB level meter, check your peak level and noise floor, and record a short clip to hear exactly what your mic picks up. Nothing is uploaded.

Test your speakers, headphones, or earbuds in the browser. Play a tone through the left, right, or both channels, sweep across the stereo field, and find out in seconds whether a channel is silent.

Test your headphones or speakers across the full audio spectrum. Play pure sine tones from 20 Hz to 20 kHz with a slider, presets, and a full sweep — hear exactly where your gear rolls off, distorts, or goes silent.

Generate a steady tone from 20 Hz to 20 kHz. Pick sine, square, sawtooth, or triangle, dial exact Hz or a musical note, and pan left or right.

Test how deep your subwoofer, speakers, or headphones really go. Play pure sine tones from 20 to 200 Hz — tap a preset, fine-tune with the slider, or sweep the whole bass range and note exactly where your low end stops.

Test every speaker in a stereo, 5.1, or 7.1 setup. Click a speaker on the room map to play a tone on that channel alone, sweep through all channels automatically, and check the subwoofer with a 30–120 Hz bass sweep.

Measure sound levels with your microphone, right in the browser. A live decibel readout in estimated dB SPL or exact dBFS, peak, average, and minimum stats, and a reference chart of everyday sounds — nothing is recorded or uploaded.

Test your headphones or headset in the browser — play a tone through the left, right, or both channels, sweep the stereo field, check the balance and wiring polarity, and quiz yourself on which ear is which.
