Abstract

A start portion of sampled sound data is cleared, and the resultant sound data free from the start portion is modified into data increasing gradually from level '0'. Thus, noise in the start portion of the recorded sound data is removed, and also sound data gradually increasing from level '0' at the start can be obtained, that is, a discontinuous point after the noise removal is precluded.
