Distortion synthesis is a group of sound synthesis techniques which modify existing sounds to produce more complex sounds (or timbres), usually by using non-linear circuits or mathematics.〔Nb. Some authors refer to these techniques as 'modulation synthesis'; e.g. Chapter 6 of 〕 While some synthesis methods achieve sonic complexity by using many oscillators, distortion methods create a frequency spectrum which has many more components than oscillators. Jean-Claude Risset was one notable pioneer in the adoption of distortion methods. Some distortion techniques are: FM synthesis,〔Dodge 1997, pp.115-138〕 waveshaping synthesis,〔Dodge 1997, pp.139-157〕 and discrete summation formulas.〔Dodge 1997, pp.158-168〕 ==FM synthesis== Frequency modulation synthesis distorts the carrier frequency of an oscillator by modulating it with another signal. The distortion can be controlled by means of a modulation index. The method known as phase distortion synthesis is similar to FM. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Distortion synthesis」の詳細全文を読む スポンサード リンク
