Method for audio synthesis

摘要

Method for audio signal synthesis from elementary audio waveforms stored in a dictionary characterized in that: the waveforms are perfectly periodic, and stored as one of their period, synthesis is obtained by overlap-adding of the waveforms obtained from time-domain multiplication of the periodic waveforms with a weighting window whose size is approximately two times the period of the signals to weight, and whose relative position inside of the period is fixed to any value identical for all the periods; whereby the time shift between two successive waveforms obtained by weighting the original signals is set to the imposed fundamental frequency of the signal to synthesize.
