check whether your phone's microphones are working correctly. Whether your voice
sounds muffled on calls, your recordings are too quiet, or one mic seems dead,
this app helps you find out in seconds — all processed live on your device.

Modern phones have multiple microphones (bottom, top/front, and rear near the
camera). If even one is blocked by dust, lint, a case, or a hardware fault, calls
and recordings can suffer. Phone Microphone Tester lets you isolate and test each
microphone individually so you can pinpoint exactly which one has a problem.

KEY FEATURES
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

● REAL-TIME DECIBEL (dB) METER
See live sound levels on a beautiful analog-style meter with a smooth animated
needle. Track current, average, and peak levels as you speak, tap, or play sound.

● TEST EACH MICROPHONE SEPARATELY
Detects the microphones and audio inputs available on your device and lets you
switch between them — bottom main mic, top/front mic, rear camera mic, and
connected Bluetooth, USB, or wired headset mics.

● LIVE WAVEFORM DISPLAY
Watch your audio signal in real time with a smooth, responsive waveform. A flat
line while you speak may indicate a blocked or faulty microphone.

● FREQUENCY SPECTRUM ANALYZER
View a real-time frequency spectrum (FFT) to check how your mic responds across
low, mid, and high frequencies — useful for spotting a tinny or muffled mic.

● BLUETOOTH, USB & HEADSET SUPPORT
Test external microphones too. Connect a headset or USB mic and verify it's
picking up sound correctly.

● PREMIUM DARK DESIGN
A clean, modern dark interface built for clarity, with sharp instrument-style
visuals that are easy on the eyes.

WHO IS THIS FOR?
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

• Anyone who thinks their microphone might be broken or blocked
• People buying a used phone who want to verify the mics before purchase
• Content creators, podcasters, and musicians checking their audio input
• Technicians and repair shops doing quick hardware checks
• Anyone whose voice sounds unclear on calls or voice messages

HOW TO USE
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

1. Open the app and allow microphone access.
2. Speak, tap near a mic, or play a sound.
3. Watch the dB meter, waveform, and spectrum respond.
4. Switch between microphones to test each one individually.
5. A healthy mic shows clear movement; a dead or blocked mic stays flat.

YOUR PRIVACY COMES FIRST
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Phone Microphone Tester does NOT record, save, or upload any audio. All sound is
analyzed live on your device and is never stored or transmitted. The microphone
permission is used only for real-time testing while the app is open.

PLEASE NOTE
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Decibel (dB) readings are an approximation for comparison and diagnostic purposes.
Phone microphones are not laboratory-calibrated instruments, so values should not
be treated as certified sound-level measurements. Available microphones and
labels depend on your device model and Android version.
