It does this by modelling the function of the lower brain to predict the effect of music on the arousal of the sympathetic and parasympathetic nervous systems. The technology is known as the Innate Neurophysiological Response to Music (INRM): a human universal, independent of culture or music preference.
X-System can entrain listeners over a period of 15-20 minutes to a lower or higher state of physical arousal, or maintain at a certain level. There are far-reaching applications of INRM in wellbeing and medicine, as well as in the navigation of large music libraries, song selection & recommendation, for both consumers and businesses.
