SignalLab is a set of components for very fast digital signal processing (DSP). The library allows very fast complex signal manipulations and visualization with zero lines of program code.
Applications include: real time data acquisition, process control, signal analysis, digital signal analysis, audio analysis, video analysis, data visualization, visual instrumentation and more.
A simple signal generation tutorial (.NET or VCL) and a more complex signal analysis tutorial (.NET or VCL) are available in the tutorials section.
