From the developer:
SigGenRP is a powerful stimulus design package that provides systematic control of stimulus variables across a range of experimental conditions. The intuitive graphical interface makes it easy to build a variety of complex signal waveforms from basic building blocks such as clicks, noise, sweeps, and sine waves. You control all aspects of the signal, such as duration, frequency, intensity, and filter settings.
