Patent ID: 7088835

Claim:
Volume control circuitry for controlling volume incrementing in a digital wavetable audio synthesizer, wherein said synthesizer is configured to provide a volume component to wavetable data addressed by said synthesizer, comprising: (a) a memory having a first storage location configured to store a current value of said volume component, and a second storage location configured to store a final value of said volume component, wherein said final value is directly programmed into said second storage location; (b) a comparator coupled to said memory for periodically comparing said current value with said final value to determine if said current value is less than, greater than, or equal to said final value; and (c) an incrementor coupled to said comparator and said memory, wherein said incrementor is configured to increment said current value in response to a determination by said comparator that said current value is less than said final value, and configured to decrement said current value in response to a determination by said comparator that said current values is greater than said final value.
