SonicKit - Speaker Water Eject

Dropped your phone in water and the speaker sounds muffled? SonicKit pushes the water out with low-frequency vibration.

It works the same way a smartwatch water eject does: a low tone drives the speaker diaphragm hard enough to force trapped droplets out of the grille. On top of that you get a dust shaker, a hearing age test, a full tone generator and a microphone analyzer - all in one app.

■ Speaker water eject - 5 modes
· Gentle 150Hz / Standard 165Hz / Strong sweep / Deep pulse 80Hz / Tidal sweep
· Go stronger if water is stubborn, gentler for older speakers
· Warns you if headphones are plugged in, and stops automatically if they are unplugged

■ Speaker dust shake - 5 modes
· Full sweep / Bass shake / Fine dust / Power burst / Ultra fine
· Vibration loosens the dust packed into the speaker grille
· Finish by brushing gently with a soft dry brush

■ Hearing age test
· From 8kHz to 20kHz - the last tone you can hear is your hearing age
· Precise mode uses a real adaptive staircase (up after 2 hits, down after 1 miss) with silent trials mixed in to catch guessing
· Test both ears together or each ear separately, then compare left-right balance and your peer percentile
· Calibrate with a 1kHz reference tone so every session is measured at the same volume
· Trend chart over time and CSV export

■ Tone Lab - a signal generator in your pocket
· 20Hz-20kHz pure tones with sine, square, triangle and sawtooth waveforms
· White, pink and brown noise, plus a notch filter for tinnitus masking
· Left/right channel isolation and phase inversion to check speaker wiring
· Full-range sweeps to hunt down rattles and dead spots
· Sleep timer with fade-out, custom preset slots, WAV export
· A left-right guessing game to test your directional hearing

■ Sound measurement (microphone)
· Live spectrum - see the room you are sitting in
· Instrument tuner with adjustable A4 reference
· Speaker response - a 10 second sweep that maps your own speaker's frequency curve
· Automatic gain control is disabled, so levels stay comparable between runs

■ Made for you if
· Your phone got wet and the sound went dull
· Your speaker has started to crackle or buzz
· You want to know how old your ears really are
· You need a tuner, an audio checkup or steady background noise

■ About the app
· 10 languages, light and dark themes
· Everything works offline (ads aside)
· The microphone is used only in the Measure tab. Nothing is recorded and nothing is uploaded
· Free. Some extras open by watching an ad, but every core feature works fully without ever watching one

■ Please note
The hearing test is a self-check for fun, not a medical diagnosis. Results vary with your device, headphones and ambient noise. Water eject can help clear water from the surface and the grille, but it cannot repair a device already damaged by liquid. Prolonged exposure to loud sound can harm your hearing, so keep the volume comfortable.
