METHOD AND APPARATUS FOR USER CONTROLLED MODULATION AND MIXING OF DIGITALLY STORED COMPRESSED DATA

A method and apparatus for generating a summation signal by programmably modulating the intensity levels of a plurality of associated channels of a selection and combining the modulated segments into a unified digital record. A pre-established and user modifiable set of channel intensity levels is provided to the user as a manufacturer recommended modulation and mixing pattern. The user creates, personalizes and subjectively improves sets of channel intensity levels from the basis of default or pre-established patterns and thus produces unique and customized summation signals. A system operator individually adjusts the relative intensity levels of each of a plurality of channels. Each channel is played at default or pre-established intensity, solely and individually, or completely masked, or at a specific relative intensity as programmed by the system operator. Intensity value sets are stored for later access, whereby the operator recreates a previously programmed summation signal. Digitized records from external origins, to include remotely transmitted data and Internet sources, and digital data received from read only memory media are processed solely or in various combinations to generate single source and hybrid summation signals.
