MicTester

MicTester is a powerful Chrome extension for analyzing audio and vibration signals captured by your device's microphone. It offers real-time digital signal acquisition with detailed visualization, zoom capabilities, and the ability to save data in .csv format for further analysis.

This extension functions as a Real Time Analyzer (RTA) to perform accurate audio spectral analysis and features automatic musical note detection for easy tuning of instruments or vocal training. It includes an oscilloscope-like trigger circuit to capture pulses and non-repetitive sound sequences. MicTester also serves as a sound level meter measuring A-Weighted SPL according to IEC61672 standards.

Supporting various audio sources—including Bluetooth mics, camcorders, and voice communication inputs—the tool even incorporates accelerometer data for infrasonic vibration analysis. Its versatile features make it suitable for testing mic performance, detecting machinery resonances, tuning musical instruments, monitoring vocal pitch, and conducting acoustic and vibration assessments.

Main features include 3D spectrum analysis, frequency peak detection, harmonic distortion measurement, customizable tuning systems, multiple display modes, and multi-language support. Whether for professional audio diagnostics or personal musical applications, MicTester provides comprehensive real-time audio and vibration analysis within a user-friendly interface.
