First Claim
1. A joint data sonification and visualization method for representing a first plurality of channels of numerical information via data visualization and a second plurality of channels of numerical information via at least one audio-frequency waveform, the at least one audio-frequency waveform perceived by a user as an audio tone with a plurality of corresponding discernable timbre attributes, further employing spatial sonic rendering, the method comprising:
- receiving multidimensional numerical data;
generating a plurality of audio-frequency waveforms, each of the plurality of audio-frequency waveforms comprising an associated fixed audio-frequency and at least one adjustable timbre attribute responsive to an associated timbre control parameter, each timbre control parameter having an associated adjustable value which can be discernibly varied within a timbre space occupied by the plurality of audio-frequency waveforms;
associating aspects of multidimensional numerical data with the at least one timbre control parameter of at least one of the plurality of audio-frequency waveforms from the plurality of audio-frequency waveforms; and
adjusting the adjustable value of each timbre control parameter responsive to an associated first value of the multidimensional numerical data according to a mapping function, the mapping function transforming first values of the multidimensional numerical data to values of associated timbre control parameters,wherein timbre and spatial location of the at least one of the plurality of audio-frequency waveforms carries information responsive to the first values of the multidimensional numerical data for presentation as data sonification to the user, andwherein at least a portion of the multidimensional numerical data is provided to data visualization software.

Abstract
Data sonification arrangements for use with data visualization so as to provide parallel perceptual channels for representing complex numerical data to a user seeking to identify correlations within the data are presented. In an implementation, several varying data quantities are represented by time-varying graphics while several other varying data quantities are represented by time-varying sound, both presented to a user to observe correlations between sonic and visual events or trends. Sonification can be used to offload some information-carrying information capacity from a visualization system, while other information can be rendered via both sonification and visualization to provide affirming or orienting redundancy. In an implementation joint and coordinated visual-sonic metaphors are used for this or other purposes. For example, data sonification can include multiple data-modulated sound timbre classes, each rendered within a stereo sound field according to a spatial metaphor that is shared with the visualization.
