Abstract:
1. A method of synthesizing music in a digital system, comprising the steps of: accessing a digital analysis waveform having a first duration, a first pitch, a first attack portion arid a first decay portion; determining a second duration and a second pitch for a synthesis waveform; computing first timing marks for the analysis waveform such that the first timing marks correspond to periodicity of the analysis waveform; computing second timing marks for the synthesis waveform such that the second timing marks correspond to periodicity of the synthesis waveform; calculating samples for each period of the synthesis waveform defined by adjacent second timing marks using samples selected from a corresponding period of the analysis waveform defined by adjacent first timing marks to form the synthesis waveform having the second pitch, the second duration, a second attack portion and a second decay portion; and wherein the step of calculating samples to form the synthesis waveform includes
