Claim Text:
1. A method of increasing user efficiency in identifying particular sounds in a waveform display of sound data without listening to the sound data, the method comprising: partitioning sound data received by a computing device to form a plurality of sound data time intervals; computing a signature for each of the plurality of sound data time intervals by the computing device based on features extracted from respective said sound data time intervals; mapping the computed signatures by the computing device to one or more colors of a color space by computing a color angle within the color space as perceptually-weighted averages calculated over a plurality of frequency bands; and controlling output of a waveform in a user interface by the computing device, in which the waveform represents the sound data and each of the sound data time intervals in the waveform have the mapped one or more colors.
