Speaker Cleaner: Water & Mic

Is your phone speaker sounding muffled, quiet, or distorted after getting wet or collecting dust? Want to test if your microphone, earpiece, stereo speakers, or Bluetooth earbuds are working properly?

Speaker Cleaner: Water & Mic is an all-in-one acoustic water ejector, dust remover, and studio-grade hardware audio diagnostic toolkit for Android. Powered by a real-time 16-bit 48 kHz Native PCM audio engine, it generates precision sound waves to help clear trapped moisture and lets you verify every speaker and microphone on your device in seconds.

💧 1-TAP WATER EJECT & SPEAKER CLEANER (5 ACOUSTIC MODES)
When water or dust gets trapped inside your speaker grille, sound becomes muffled and low. Our specialized acoustic cleaning waves create targeted membrane vibrations to help push out liquid droplets and shake loose fine dust:
• Water Eject Mode (165 Hz Liquid Wave): Resonant low-bass sine wave engineered to push trapped water droplets from speaker meshes.
• Dust & Dirt Shaker (145 Hz / 290 Hz): Dual-frequency alternating pulse designed to dislodge stubborn dust particles.
• Deep Pulse & Short Burst Modes: Rhythmic air-pressure bursts for heavy moisture buildup.
• Custom Frequency Cleaner (80 Hz – 400 Hz): Manually dial in the exact resonant frequency for your phone model.

⚡ 45-SECOND QUICK AUDIO CHECK
Buying or selling a used phone, or checking your device after a drop or splash? Run our guided 4-step hardware diagnostic:
1. Loudspeaker & Earpiece Frequency Check
2. True Left / Right Stereo Channel Isolation
3. Live Microphone Capture & Voice Clarity Test
4. Active Audio Route & Headphone Verification
Generate a clean, shareable diagnostic report card with a single tap!

🎙️ DUAL MICROPHONE STUDIO & LIVE VU METER
Modern smartphones have multiple microphones. Test each one individually to diagnose call audio issues:
• Switch between Primary Bottom Call Mic, Secondary Top Camcorder Mic, Voice Recognition, and Unprocessed RAW input.
• Monitor real-time RMS and Peak dBFS levels on a studio VU meter with automatic clipping detection.
• Record, replay, and compare your voice clarity instantly.

🔊 STEREO LEFT / RIGHT & HEADPHONE TESTER
Verify true stereo separation on built-in dual speakers, wired 3.5mm / USB-C headphones, and wireless Bluetooth earbuds:
• Isolate Left Only, Right Only, or Balanced Stereo channels.
• Automatic mono-route detection warns you when a single speaker is active.
• Test call receiver (earpiece) vs. main loudspeaker routing.

🔁 AUTO ACOUSTIC LOOPBACK TEST (SPEAKER → MIC)
Hands-free automated verification! The app plays 4 reference frequencies (350 Hz, 1 kHz, 2.5 kHz, and 4.5 kHz) through your speaker while simultaneously analyzing microphone input via a 2048-point FFT engine to verify acoustic response across low, mid, and high bands.

⏱️ BLUETOOTH AUDIO LATENCY PING (MS)
Experiencing audio lag in gaming or videos with wireless earbuds? Measure your exact round-trip acoustic delay in milliseconds (ms) using our high-precision 2200 Hz pulse detector.

📈 REAL-TIME 64-BAND FFT SPECTRUM ANALYZER & AUDIO LAB
• Live 64-Band Logarithmic Spectrum Analyzer (20 Hz – 20 kHz) with peak-hold and dominant Hz tracker.
• Pure Tone & Frequency Generator: Sine, Square, Triangle, and Sawtooth waves (20 Hz – 20,000 Hz), logarithmic frequency sweeps, and White / Pink noise.
• Bass Rattle Stress Test (30 Hz – 120 Hz) & High-Frequency Hearing / Tweeter Check.
• Voice Lab FX: Record and A/B compare 6 real-time DSP presets (Normal, Bass Boost, Treble Air, Deep Radio, Bright, and Speech Clarity).

🔒 100% PRIVATE & ON-DEVICE
• No account or cloud upload required — all test history stays locally on your phone.
• Microphone access is used strictly during active audio tests and temporary buffers are cleared automatically.
