Is your microphone sounding muffled, quiet, or static?

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.
