Abstract

Split-sideband synthesis (SpSB)—which is related to the well-known principles of waveshaping, single-sideband modulation, and frequency modulation—offers the possibility of creating four independent sideband outputs: upper, lower, odd, and even. Novel spectra and timbres can be created by the way in which these four outputs are combined. As with similar techniques for distortion synthesis, an SpSB process is controlled by the modulator and carrier frequencies as well as the modulation index. The technique can also be used as an adaptive effect applied to arbitrary monophonic signals. A number of sound samples illustrate the technique.
