What we make
Speaker Refresh brings together a low water-eject tone, sound sweeps, a stereo listening test, and an adjustable tone generator. The tools are free to use without an account, installation, or microphone permission.
Useful controls, clear limits
We put playback controls before long explanations. Every session stops automatically, and you can stop sooner. A tone may help move loose surface droplets, but it cannot diagnose internal liquid, remove stuck dirt, or repair damaged hardware.
How the audio is made
Audio is generated in your browser using sine waves. We do not stream competitor recordings or record your speaker. The audio explanation lists the actual frequencies, durations, and testing limits.
How we approach speaker-care guidance
Guides separate media playback, physical cleaning, liquid exposure, and repair. Where device-specific care matters, we link to manufacturer instructions. We do not claim manufacturer endorsement, universal device compatibility, or a guaranteed repair rate.
