Abstract
A data sonification system for representing a plurality of channels of numerical information is described wherein the rate of the periodic modulation is itself used as a vehicle for carrying information of at least one component of the multidimensional numerical data. The data sonification system includes a plurality of audio waveform generator elements. Each of the audio waveform generator elements generates an associated audio frequency waveform. Each audio frequency waveform has an audio frequency parameter and at least one timbre modulation parameter having a settable value. The timbre modulation parameter affects the timbre of the audio waveform. The data sonification system includes a mapping element for associating aspects of multidimensional numerical data with the timbre modulation parameter of each audio frequency waveform. The mapping element sets the value of the timbre modulation parameter in response to multidimensional numerical data and/or periodic modulation.
