Sound Synthesis by Fractional Waveshaping

Document Thumbnail

A nonlinear sound synthesis technique that uses a sinusoidal input signal and a rational shaping function is described. Complex spectrum evolutions are easily obtainable by varying different parameters. The global spectrum shape is essentially defined by only two parameters, those controlling the bandwidth and the formant position. multiplication by a carrier allows harmonic and inharmonic spectra to be obtained.
