Appl. No.:

10/946430

Inventors:

Ray Graham - Walnut Creek CA, US

International Classification:

G10L 21/00

US Classification:

704278000

Abstract:

An improved method and apparatus for controlling the voice channels in sound processors includes: programming a first voice channel to instruct a second voice channel to execute an event when a trigger condition occurs; determining by the first voice channel that the trigger condition has occurred; and instructing the second voice channel to execute the event by the first voice channel. Thus, the need for the CPU to properly time the programmer's desired voice processing events is reduced by having the voice channels themselves be pre-instructed to control another voice channel(s) upon meeting a certain trigger condition. Chains of voice channels are possible and can be as simple or complex as desired. Accurate channel-to-channel event timing is thus possible. Since no interrupts or the polling of status registers is needed, the demands on CPU resources are reduced. System bus bandwidth is also freed for the use of other system components.

Abstract:

The invention is a method and system for applying more effects to voices in an input sound than is capable of being supported by a sound processor. Aspects of the invention include identifying at least one of the voices of the input sound as a voice bus channel; and during processing of the input sound, inputting and adding sound that was mixed from outputs of previously processed voices to the voice bus channel to create a summed result. An effect specified for the voice bus channel is then applied to the summed result, thereby applying the effect to the previous the process voices.
