Abstract

PURPOSE: To ensure the reproduction for the voice featuring the large dynamic range with a high S/N ratio by recording previously the higher harmonic frequency with the necessary level every passage according to the level of the aural signal.
CONSTITUTION: The aural signal is partitioned into passages A, B, C... in accordance with its level each. Then the higher harmonic frequency signals outside the audible frequency band are recorded on passages A, B, C... with the levels set according to the aural levels of these passages. As a result, the dynamic range is decreased substantially for the recording of the voice featuring the large dynamic range due to the sum of the voice and the higher harmonic signal. Accordingly, if the aural signal is divided via LPF, HPF and the like and after reproduction, the aural signal featuring the large dynamic range can be reproduced with a high S/N ratio.
