Method and system for modification of audio signals

摘要

The invention is concerned with a method and system for modification of audio signals including pitch-bending of the audio signals in accordance with a control signal. The audio signal consists of an input signal defining the point at which the audio signal is received and of a control signal defining the desired change of the signal pitch. The method comprises digitizing and storing samples of the input signal in a data file memory in such a form that each piece of signal data is placed in a queue having an input pointer that locates the next available storage location and output pointer that locates the next location to read from the queue.
