DATK 1.0

Several audio effects devices deliberately add nonlinear distortion to the processed signal in order to create a desired sound. When creating virtual analog models of nonlinearly distorting devices, it would be very useful to carefully analyze the type of distortion, so that the model could be made as realistic as possible. While traditional system analysis tools such as the frequency response give detailed information on the operation of linear and time-invariant systems, they are less useful for analyzing nonlinear devices.

Furthermore, although there do exist separate algorithms for nonlinear distortion analysis, there has not been - until now - any easy-to-use tool for rapid analysis of distorting audio systems. The DATK software allows the user to measure the distortion behavior of an effects device (distortion pedal, compressor, guitar amplifier, microphone preamp) or a software plugin.
