Vibration is a comprehensive vibration spectrum analyzer designed for iPhone and iPod Touch devices. It utilizes the built-in accelerometers, gyroscope, and microphone to acquire and display time series data. The app can remove DC bias, apply a Hamming window, and perform FFT analysis to generate frequency spectra. With a sensitivity of approximately 0.02g and a range of ±2g, Vibration can effectively analyze the vibrations of various machinery.

In addition to predictive maintenance applications, Vibration serves as a portable alternative to commercial spectrum analyzers. Users can easily adjust sample rates, data acquisition length, and vertical scales. The software mimics an oscilloscope-based spectrum analyzer, offering flexible settings and easy data sharing options for documentation purposes.
