Speaker and Headphone Tests
Play sound through each speaker, check left and right, test bass and surround, and generate tones and noise.
Speaker and headphone tests
Sound Test
Hear if your sound works, then check left, right and every speaker by name.
Left Right Audio Test
Hear left and right named from each side, then check balance, polarity and mono.
Speaker Test
Play every speaker by name, then sweep for buzzing, damaged or reversed speakers.
Surround Sound Test
Hear all six channels of a 5.1 system named from their own speakers.
Headphone Test
Hear left and right in each ear, then compare both drivers for buzz, balance and polarity.
Bass Test
Tones from 20 to 200 Hz, a bass sweep, a rattle finder and your lowest audible note.
7.1 Surround Sound Test
Hear all eight channels of a 7.1 system or virtual 7.1 headset named in turn.
Subwoofer Test
Play the subwoofer channel, set the crossover and phase, and find rattles.
Headset Test
Test both earcups and the headset mic, then let the mic listen to the earcups.
Spatial Audio Test
Move a sound around and over your head, then score your sense of direction.
Audio Latency Test
Measure how late Bluetooth headphones, speakers or a TV play sound, in milliseconds.
Dolby Atmos Test
Hear sound pass overhead, then confirm Dolby Atmos is really on for your device.
Headphone Burn-In
Hours of pink, brown and white noise, sweeps and rests for new headphones, with a running total.
Speaker cleaning
Tones and noise
Brown Noise
Deep brown noise with an exact 1/f² spectrum, a sleep timer, a slow fade and stereo or mono.
Pink Noise
Exact 1/f pink noise with a sleep timer, a -20 dBFS calibration level and band limits.
Tone Generator
Play any frequency from 1 Hz to 20 kHz in four waveforms, with beats, a timer and WAV download.
Frequency Sweep
Glide a tone from 20 Hz to 20 kHz, mark where it fades or rattles, and save the sweep as WAV.
White Noise Generator
True white noise with a sleep timer, slow fade out, stereo or mono and a live spectrum display.
Hearing Frequency Test
Find the highest and lowest tones you can hear in each ear, at a safe level.
Is the sound working?
The sound test plays a test sound with one click, then lets you check each speaker. The left right audio test plays each channel on its own so swapped or silent sides are obvious, and the headphone test adds checks made for headphones and earbuds. A gaming or office headset gets its earcups and mic checked together on the headset test. The speaker test names each speaker out loud and finds blown, humming or out of phase speakers. Home theater owners can step through every channel with the surround sound test and the 7.1 surround sound test.
Bass and space
The bass test and subwoofer test play low tones step by step to find rattles and the lowest note your speakers reach. The spatial audio test moves a sound around your head through headphones, and the Dolby Atmos test shows how to confirm Atmos is really on.
Delay and hearing
The bluetooth audio delay test measures how far sound lags behind the picture, and the hearing frequency test finds the highest and lowest tones each ear can hear.
Tones, sweeps and noise
The tone generator plays any frequency from 1 Hz to 20 kHz, the frequency sweep glides across a range to find buzzes and gaps, and the noise generators play white noise, pink noise and brown noise for testing, focus or sleep. New headphones can run a timed program on the headphone burn in tool.
Phone speakers and water
After a phone gets wet, water eject plays the low tone that pushes water out of the speaker grille, and the speaker cleaner helps with muffled or dusty speakers.
No sound at all?
The no sound on computer guide fixes output devices, drivers and settings on Windows and Mac.
