The Signal Processing Component Library for .NET is a comprehensive library of .NET components designed for rapid development of signal processing applications in the sound and vibration marketplace. Each component contains properties and methods that can be used to perform single-channel (spectrum, auto-spectrum, power spectral density) and two-channel (frequency response functions, cross spectrum functions) FFT operations, and to calculate signal metrics on time-domain data. Signal metrics include input below full-scale (IBF), total harmonic distortion (THD), signal-to-noise ratio (SNR), signal-to-noise and distortion (SINAD), spurious free dynamic range (SFDR), and effective number of bits (ENOB). The open design architecture allows hardware-independent support — measurements data can be used from any device.
