Non-looped continuous sound by random sequencing of digital sound records
DCFirst Claim
1. A method of generating random sequenced sound comprising:
- providing a group of pre-recorded, fixed sound segments;
for each sound segment, assigning a corresponding weighted probability of being played;
randomly selecting one of the sound segments according to the weighted probabilities;
playing the selected sound segment; and
continuously repeating said selecting and playing steps, thereby generating non-looped continuous sound for as long as may be desired.

Abstract
Several short segments of an otherwise continuous sound are recorded and stored in a digital memory. The stored segments are concatenated together to form a sound sequence of arbitrary length, based on selecting the next sound segment according to some statistical algorithm. The selected algorithm may be simply a random or pseudo-random selection, or it may provide a probability weighting to emphasize some sound records over others, or some combination of factors also affected by external stimuli such as light, heat or operator input. Apparatus for generating random sequenced digital sound are disclosed. Another aspect of the invention is logical sequence sound in which the selection of sound segments proceeds according to a logical sequence which is programmable.
