Free Speaker Tools
Fix My Speaker provides four browser-based audio tools — water ejection at 165 Hz, dust removal from 8 kHz to 16 kHz, a full-range tone generator, and a stereo channel test. All of them run client-side with no download, no account and no cost, and the homepage tool bundles the cleaning modes into one place if you would rather not choose.
Which tool do you actually need?
The sound went wrong suddenly, near water
Use Water Eject. A low tone moves the diaphragm far enough to break the surface tension holding droplets in the grille. Act inside the first ten minutes if you can.
The sound faded gradually over months
Use Speaker Cleaner. That pattern is dust, and dust responds to fast high-frequency oscillation rather than the low water tone. The two modes target opposite problems.
You are not sure whether the speaker is faulty at all
Use Speaker Test first. Isolating left from right tells you whether one driver is dead, both are fine, or the problem was never the hardware.
You want to know if 165 Hz is right for your phone
Use the Resonance Finder. It sweeps your speaker and measures the peak, so you get your device's number instead of the number the category assumes. No other tool in this niche measures anything.
You need a specific frequency for something else
Use the Tone Generator. Any frequency from 20 Hz to 20 kHz, four waveforms, per-channel output — for hearing checks, finding rattles, or setting a reference level.
Cleaning & test tools
Water Eject
Push trapped water out of a speaker with a calibrated 165 Hz tone.
Speaker Cleaner
Sweep 8 kHz–16 kHz to dislodge dust and pocket lint from the grille mesh.
Tone Generator
Play any frequency from 20 Hz to 20 kHz with four waveforms.
Speaker Test
Check left and right channels independently and confirm stereo wiring.
Resonance Finder
Measure which frequency your speaker actually pushes hardest, using your own microphone.
Common questions
Which tool should I use first?
Start with Speaker Test if you are not certain the speaker is at fault, because it separates a hardware problem from a settings problem in under a minute. If you already know it is blocked, use Water Eject for sudden muffling and Speaker Cleaner for gradual decline.
Are all these tools free?
Yes, all of them, with no account and no installation. Every tool runs client-side in your browser using the Web Audio API. The site is funded by advertising rather than by charging for the tools. There is no usage limit and no account. Because everything runs in your browser rather than on a server, each use costs nothing to provide, so there is nothing to meter.
Do any of these tools record audio?
Only the Resonance Finder uses your microphone, and it connects the stream straight to an analyser to read frequency levels. Nothing is recorded, stored or uploaded, and the stream stops when the sweep ends. The other tools only play audio and never request microphone access at all, so no permission prompt appears for them.
Can these tools damage my speaker?
No. They stay inside the frequency range your speaker already reproduces during ordinary music playback and cannot exceed your device's own maximum output. The laptop tool additionally caps volume at 80 percent because small drivers distort before phone speakers do.
What if none of the tools fix my speaker?
Then the problem is not a blockage. Distortion at low volume, one silent channel, or no improvement across several attempts on different days all point to mechanical damage, which no acoustic tool can reach. Run the speaker test first to confirm which channel is affected. A single dead channel with a working opposite side is a strong indicator of hardware failure rather than a blockage.
