This paper describes a new objective parameter, called “Difference Level” that could be used for preliminary technical estimation of signal degradation in various audio circuits – digital and analogue, hardware and software based. This parameter could be considered either as an extension of THD for non-periodic signals, or as one of the estimations of widely used difference signal.
