ABSTRACT:
This eliminates the possibility of the generation of quantizing noise in a small amplitude portion of the waveform when it is compressed to an 8-bit quantized form. The present invention is effective when a percussive or like musical tone, provided in the form of a 16-bit quantized digital form is compressed to the 8-bit quantized form.
