ABSTRACT:
A recording method includes converting an original sound signal into a digital sound signal in a selected conversion range, selecting the conversion range in accordance with the amplitude information of the original sound signal, and storing and recording the digital sound signal. The apparatus includes a first selecting arrangement for selecting a conversion range which corresponds to amplitude information of an original sound signal, a converting arrangement for converting the original sound signal into a digital sound signal in the conversion range selected by the selecting arrangement, and a first memory for storing the digital sound signal converted by the first converting arrangement.
