MicTester

Microphone testing and audio analysis just became professional-grade with MicTester. Whether you're diagnosing hardware performance, tuning instruments, or analyzing acoustic environments, this app transforms your Android device into a precision measurement tool that rivals dedicated lab equipment.

Capture and visualize microphone signals in real time with full control over sampling and display. Zoom down to individual samples, examine waveforms with oscilloscope-grade trigger functions, or export raw data to CSV for detailed post-analysis. Multiple input sources—internal mics, external microphones, Bluetooth devices, camcorder audio, and streamed WAV files—give you flexibility across countless testing scenarios. If your device has dual microphones, stereo mode unlocks deeper analysis capabilities.

Perform accurate audio spectral analysis using advanced Real Time Analyzer features. The 3D spectrum visualization modes—waterfall and XYZ displays—reveal how frequencies evolve over time, making it simple to spot machinery resonances, identify feedback frequencies, and detect acoustic anomalies. Automatic musical note detection across ten octaves helps you tune guitars, pianos, and other instruments with precision, or train your vocal pitch by monitoring real-time dominant frequency output. Choose from standard tuning systems at 432Hz, 435Hz, or 440Hz.

Measure sound levels accurately using A-Weighted SPL metering compliant with IEC61672 standards—essential for acoustic compliance testing and environmental noise assessment. Calculate THD+N measurements to evaluate audio device quality. Full pan and pinch zoom, XY cursors, and vertical measurement cursors give you granular control over data inspection. Multiple frequency scales (linear, log10, log2) and display modes (curve, bars, points) adapt to your analysis needs.

Vibration analysis at infrasonic frequencies becomes possible by leveraging your device's accelerometer—ideal for machinery monitoring and structural diagnostics. Trigger functions including single, auto, normal, pre-trigger, slope, and level detection let you capture non-repetitive events and single pulses effortlessly. Autorange and averaging functions streamline measurement workflows.

Supports sampling frequencies up to 192kHz for WAV streams and 96kHz for analog input, ensuring high-resolution capture. Save screenshots and measurement data to device memory or attach them directly to emails for sharing with colleagues. Comprehensive user guide and multi-language support (English, Spanish, German, French, Italian, Russian) make MicTester accessible worldwide. Note: This is the trial version with limited functions—upgrade to MicTester Pro for full capabilities.
