Abstract
Abstract PURPOSE:To obtain automatically a proper output, by controlling an amplification factor of an output amplifier in accordance with the maximum amplitude of a stored sound. CONSTITUTION:An output amplifier gain controlling circuit 9 stores the maximum value of a sound signal converted to a digital signal, which is obtained from an encoding circuit 6. When reproducing a sound, the output amplifier gain controlling circuit 9 controls the gain of an amplifier 4 so that a sound outputted from a loudspeaker serving also as a microphone 3 is not saturated but can be heard with a large sound.
