Mic Test: Check Microphone

Is your microphone sounding muffled, quiet, or static?

Mic Test is a clean, professional, and powerful audio utility designed to diagnose and test any microphone connected to your iOS device. Whether you are checking your built-in iPhone microphone, a wired headset, AirPods, or a professional Bluetooth microphone, Mic Test provides instant visual and audible feedback.

FEATURES:

TWO CORE TEST MODES:
- Direct Sound (Raw Mode): Capture the raw, unfiltered audio stream directly from the hardware. Bypass system signal processing to evaluate true frequency response and hardware static. Save recordings as high-fidelity, lossless WAV files.
- Communication (Processed Mode): Apply iOS-native echo suppression, noise reduction, and automatic gain control. Simulate exactly how you sound during standard phone calls, VoIP apps, or virtual meetings. Saves as compact M4A files.

REAL-TIME DECIBEL ANALYSIS:
- View live input levels with our high-precision decibel (dB) meter.
- Monitor input spikes and ambient room noise to perfectly calibrate your voice level.

HARDWARE & DEVICE DIAGNOSTICS:
- Instantly identify active audio input routes (Built-in Mic, Wired Headset, Bluetooth, or AirPods).
- View detailed hardware specifications, standard sample rates (44,100 Hz), and audio channel mapping.
- Refresh route mapping dynamically when plugging/unplugging headphones or connecting wireless devices.

SMART AUDIO LIBRARY:
- Browse and play back all your diagnostic tests directly within the app.
- View detailed metadata for every recording: date, time, test mode, active hardware device used, file size, and duration.
- Rename and organize your recordings for easy tracking.
- Share WAV and M4A audio files directly via AirDrop, Email, Messages, or cloud storage.
- Fully integrated with iOS Files sharing - access and copy your raw recordings straight from the native Apple "Files" application.
