Synthesised sound animation - an inexpensive way of phase-shifting a sawtooth waveform

9-52 — elektor september 1982 synthesised sound animation The recognised method used by syn- thesiser builders is, the one already mentioned: several VCOs in parallel. Readers wishing to know more about this particular technique should refer to the Elektor Formant books. We are certainly not going into it in this article simply because, the alternative intro- duced here, is a more viable proposition. And, anyway, apart from being expens- ive the results achieved by the conven- tional method can sometimes be com- pletely unpredictable. In our opinion the best solution is to use a single VCO and still produce the same end result. First of all we need a single VCO producing a sawtooth wave- synthesise sound animation an inexpensive way of phase-shifting a sawtooth waveform Sound animation or to put it in another way: the changing, delaying or phase shifting of any periodic waveform, enhances any final result, sometimes quite dramatically. One way of achieving this is by using sever...
