1. A data sonification system for representing a plurality of channels of numerical information via a plurality of corresponding discernable variations of timbre of at least one of a plurality of audio-frequency waveforms, the at least one of the plurality of the audio-frequency waveforms being perceivable by a user as comprising a plurality of audio tones having at least one corresponding discernable timbre attribute, the data sonification system comprising:

  • a plurality of audio-frequency waveform generators, each of the plurality of audio-frequency waveform generators generating an associated one of the plurality of the audio-frequency waveforms, wherein each of the associated ones of the plurality of the audio-frequency waveforms comprises a fixed audio-frequency and at least one adjustable timbre control parameter, each of the at least one of the adjustable timbre control parameter having an associated adjustable value which can be discernibly varied within a timbre space occupied by the plurality of the audio-frequency waveforms; and

    a mapping element for mapping aspects of multidimensional numerical data with the at least one of the adjustable timbre control parameters of each of the associated ones of the plurality of the audio-frequency waveforms,wherein for the associated ones of the plurality of the audio-frequency waveforms the mapping element adjusts a value of the at least one of the adjustable timbre control parameters responsive to values of the multidimensional numerical data,wherein for the plurality of the audio-frequency waveforms the timbre of the associated ones of the audio-frequency waveform carries information responsive to values of underlying data for presentation to a user, andwherein the associated ones of the plurality of the audio-frequency waveforms and their respective adjustable timbres are arranged to provide a plurality of data-modulated sound timbre classes within the timbre space.
