Detecting Changes in Audio Signals by Digital Differencing

A software application has been developed to provide an accessible method, based on signal subtraction, to determine whether or not an audio signal may been perceptibly changed by passing through components, cables, or similar processes or treatments. The goals of the program, the capabilities required of it, its effectiveness and the algorithms it uses are described. The program is made freely available to any interested users for use in such tests.
