The wavetest tool is a good example of my expertize in measurement science and signal processing. The tool allows accurate measurement of signals either from an audio capture device, the Digilent AD2 USB oscilloscope, or a .wav file. If analyzes the signal in many ways and calculates performance parameters. It also allows demodulation, which can be used to analyze jitter, wow, flutter and even RF signal modulations.
