Data Translation announces the release of a .NET class library for FFT and signal processing operations. The library supports quick and easy development of sound and vibration applications, independently of the measurement hardware used. Key features include tools for performing single-channel and two-channel FFT operations and calculating the relevant signal metrics. For single-channel FFT operations, the .NET library provides routines for calculating the spectrum, auto spectrum and Power Spectral Density (PSD). The functionality for two-channel FFT operations includes frequency response, cross spectrum and coherence functions. In addition to flexible windowing and averaging options (Hamming, Hanning, Blackman, Bartlett, etc.), the object-oriented class library also features routines for calculating typical signal metrics, including Input Below Full Scale (IBF), Total Harmonic Distortion (THD), Signal to Noise Ratio (SNR) and many more.
