Abstract
A waveform data looping system has waveform data sampled for a predetermined time period and stored in a first memory. Data read-out is started at a looping start point in the time period and, after a readout at an end point is completed, the readout is again started at the starting point, repeatedly. The system includes a processing device for dividing the data stored in the first memory into two sections at an intermedial point of the predetermined time period, multiplying the data in the preceding section such that a data value at the start point is 0% and that at the intermedial point is 100% and that between the start and the intermedial points varies between 0% and 100% and the data in the subsequent section such that the data at the intermedial is 100% and that at the end point is 0% and that between the intermedial and end points varies between 100% and 0%, and adding the multiplied preceding data section and the multiplied subsequent data section. A second memory stores an output of the processing device, and a reproducing devices reads and reproduces the data stored in the second memory from the start point to the intermedial point repeatedly.
