ABSTRACT:
A double buffer system of a small storage capacity is employed for reducing the noise generation in musical waveforms. The operations of the buffers are utilized for performing an interpolation between waveforms and between successive sample points of each waveform, whereby the number of sample points of the waveform being read out is increased to smooth its level variation, producing a good quality musical tone as if it were obtained by quantizing the synthesized musical waveform.
