Abstract:
Volume component circuitry for a digital wavetable audio synthesizer, wherein said synthesizer is at least capable of addressing linear wavetable data, comprising:(a) summing circuitry configured to sum multiple logarithmic volume components;(b) a first storage device, coupled to said summing circuitry, configured to store a right volume value resulting from the summation of multiple logarithmic volume components by said summing circuitry;(c) a second storage device, coupled to said summing circuitry, configured to store a left volume value resulting from the summation of multiple logarithmic volume components by said summing circuitry; and(d) multiplication circuitry, coupled to (i) said first and said second storage devices, and (ii) a bus configured to transport said linear wavetable data to said multiplication circuitry, wherein said multiplication circuitry is configured to multiply said linear wavetable data by said right and said left volume values by virtue of being configured to convert said right and said left volume values from a logarithmic representation to a linear representation during said multiplication.
