Abstract
A method and system for analyzing audio (eg. music) tracks. A predictive model of the neuro-physiological functioning and response to sounds by one or more of the human lower cortical, limbic and subcortical regions in the brain is described. Sounds are analyzed so that appropriate sounds can be selected and played to a listener in order to stimulate and/or manipulate neuro-physiological arousal in that listener. The method and system are particularly applicable to applications harnessing a biofeedback resource.
Claims35
A computer implemented system for analysing sounds, such as audio tracks, or any other types of sounds, the system including a processor programmed for automatically analysing sounds according to musical parameters derived from or associated with a predictive model of the neuro-physiological functioning and response to sounds by one or more of the human lower cortical, limbic and subcortical regions in the brain;
- and in which the system analyses sounds so that appropriate sounds can be selected and played to a listener in order to stimulate and/or manipulate neuro-physiological arousal in that listener, in which values of rhythmicity, harmonicity and turbulence for a given track are combined and mapped to an n dimensional point p characterizing physiological excitement state E, and where the system determines excitement using an equation that links E to I, R and T, where E is the excitement state, R is the rhythmicity, I is the inharmonicity and T is the turbulence.
A computer implemented system for analysing sounds,
- such as audio tracks, or any other types of sounds, the system including a processor programmed for automatically analysing sounds according to musical parameters derived from or associated with a predictive model of the neuro-physiological functioning and response to sounds by one or more of the human lower cortical, limbic and subcortical regions in the brain;
- and in which the system analyses sounds so that appropriate sounds can be selected and
- played to a listener in order to stimulate and/or manipulate neuro-physiological arousal in that listener, wherein the musical parameters relate to rhythmicity, and wherein the system determines rhythmicity using an equation that relates R to B and S, and where R is rhythmicity, B is beats per minute, and S is the mean of the beat strength, where the beat strength is the ratio of the energy before the beat to the energy after it.
A computer implemented system for analysing sounds,
- such as audio tracks, or any other types of sounds, the system including a processor programmed for automatically analysing sounds according to musical parameters derived from or associated with a predictive model of the neuro-physiological functioning and response to sounds by one or more of the human lower cortical, limbic and subcortical regions in the brain;
- and in which the system analyses sounds so that appropriate sounds can be selected and
- played to a listener in order to stimulate and/or manipulate neuro-physiological arousal in that listener, wherein the musical parameters relate to rhythmicity, that determines rhythmicity using an equation that relates I to C and H, where I is inharmonicity, C is linear harmonic cost and H is instantaneous harmonicity.
A computer implemented system for analysing sounds,
- such as audio tracks, or any other types of sounds, the system including a processor programmed for automatically analysing sounds according to musical parameters derived from or associated with a predictive model of the neuro-physiological functioning and response to sounds by one or more of the human lower cortical, limbic and subcortical regions in the brain;
- and in which the system analyses sounds so that appropriate sounds can be selected and
- played to a listener in order to stimulate and/or manipulate neuro-physiological arousal in that listener, wherein the musical parameters relate to turbulence, being a measure of rate of change and extent of change in musical experience, wherein the system determines turbulence using an equation that links T to H and P, where T is turbulence, H is harmonicity and P is energy during peak volume.
