1. A method of sonifying brain signals using a digital processor system that comprises at least one processing unit, the method comprising:

  • filtering, with a front-end module coupled to the digital processor system, a continuous time-domain sensor signal representing brain activity of a subject obtained from at least one sensor in order to generate a filtered continuous time-domain sensor signal;

    producing a continuous time-domain signal representing the brain activity of the subject from the filtered continuous time-domain sensor signal using the digital processor system, the continuous time-domain signal having a time varying signal value;

    concurrently generating a plurality of continuously time-varying acoustic parameters from the continuous time-domain signal using the digital processor system, the plurality of continuously time-varying acoustic parameters including a vowel-control parameter, an intensity-control parameter, and a pitch-control parameter, wherein at least three of the parameters in the plurality of continuously time-varying acoustic parameters are continuously modulated in proportion with at least the continuous time varying signal value of the time-domain signal during concurrent generation;

    driving, with the digital processor system, an audio synthesizer using the concurrently generated plurality of continuously time-varying acoustic parameters, including the vowel-control parameter, the intensity-control parameter, and the pitch-control parameter, to produce a representation of an acoustic signal corresponding to the brain activity of the subject represented by the continuous time-domain signal;

    performing continuous audio playback of the representation of the acoustic signal using the digital processor system, wherein performing the continuous audio playback comprises audibly providing, with at least one speaker, the representation of the acoustic signal for diagnosis and/or treatment of a condition of the subject.
