A free speaker test and speaker cleaner, right in your browser

Speaker Test 'n' Cleaner is a free, browser-based toolkit for two everyday audio problems: making sure your speakers are wired and positioned correctly, and getting water or dust out of them when they stop sounding right. There's nothing to install and no account to create — open a tool, press play, and you're testing or cleaning within seconds.

A sound test for stereo, headphones, and left/right wiring

The Speaker Test tool starts with the question most people actually have: is my left speaker really on the left? Run a left/right speaker test on any pair of speakers, a soundbar, or a headphone set, and confirm each channel — left, right, center, and both together — is coming from where it should. Because it's a sound test online, there's no software to download and no drivers to fuss with; it uses your browser's own audio engine, so it works the same way on a laptop, a desktop, or a phone. Use it as a quick stereo sound test after plugging in new speakers, moving furniture, or troubleshooting audio that suddenly sounds lopsided or mono.

Surround sound test: 5.1, 7.1, and custom room layouts

Switch the same tool to Surround Sound Test mode and you get a proper surround sound test built around a room diagram — drag each speaker icon until it matches where your actual speakers sit, then step through every channel in order. It handles a 5.1 surround sound test and a 7.1 surround sound test out of the box, and a Customize option lets you add or remove speakers for setups that don't match a standard layout, like a 9.1 room or an odd number of surrounds. When your operating system reports true multichannel output, each speaker gets genuinely discrete audio; on stereo-only hardware — including most headphones — the same layout is simulated with binaural panning, so you still get a meaningful directional check even without a real surround receiver.

Speaker cleaner sound: clear water and dust without opening the case

The Speaker Cleaner is a tuned speaker cleaner sound built to fix my speaker moments — a phone dropped in a puddle, a laptop speaker gone muffled after a summer at the beach, dust rattling around a Bluetooth speaker's mesh. It plays two distinct patterns: a low-frequency tone that pushes the speaker cone through a wide range of motion to physically eject trapped water, and a faster, higher-pitched flutter designed as a speaker dust cleaning sound that shakes loose debris without needing that same large excursion. As a phone speaker cleaner sound it's tuned specifically for the small, high-frequency drivers in phone earpieces and speakers, where trapped water shows up as a crackly or underwater-sounding call speaker. A live waveform shows the tone actually driving your speaker, so you can confirm it's working before you trust your ears. Run it in short cycles to clear speaker sound quality gradually rather than one long blast, and always dry off visible moisture first — see the in-app before-you-start checklist for the full safety steps.

When to reach for each tool

A few situations where these tools earn their spot in a bookmark bar: you just unboxed a new pair of speakers or a soundbar and want a fast sound test before trusting the wiring; a movie or game suddenly sounds like it's coming from the wrong side and you need a quick left/right speaker test to rule out a swapped cable; you've hooked up a receiver for the first time and want a genuine 5.1 or 7.1 surround sound test instead of trusting a menu setting you can't hear; your phone went through the wash, the pool, or the rain and every call sounds muffled until you clear speaker sound with a proper cleaning pattern; or a laptop speaker has been collecting pocket lint and desk dust for a year and needs a speaker dust cleaning sound rather than a cotton swab jammed into the grille. In every case, the tools give you a direct, audible answer in under a minute instead of a guess.

Why run these tools online instead of guessing

Both tools run entirely client-side using the Web Audio API — no audio is ever recorded, uploaded, or stored on a server, and the only thing saved locally is your custom surround layout, so it's there the next time you visit. That makes Speaker Test 'n' Cleaner a fast first move any time something sounds off: run the sound test before you blame a "broken" speaker on hardware, and run the speaker cleaner before you assume water damage means a trip to the repair shop or a bag of rice overnight. It's completely free, there's no signup wall between you and the first tone, and it works on desktop and mobile browsers alike — the Speaker Cleaner in particular is built with phone speakers as the primary target, since that's where water and dust damage shows up most often. Every test tone is also deliberately identical across channels, on purpose: the goal is to isolate position and function, not to entertain you with different pitches that make it harder to judge where a sound is actually coming from.

Both tools are also built to be forgiving of real-world setups. The surround room diagram isn't locked to a textbook layout — drag speakers to match a couch pushed against a wall or a rear channel mounted higher than usual, and the Customize panel handles anything from a stripped-down 2.1 to a sprawling 9.1 setup. The cleaner runs in short, repeatable cycles rather than one long blast, because that's both safer for the driver and easier to judge — you can stop as soon as the crackle clears instead of running a fixed timer past the point it's doing anything useful.
