ABSTRACT:
An apparatus for processing audio signals is provided with a memory for storing the audio signals. The audio signals are written in the memory at write addresses in the memory. The audio signals are read from the memory in accordance with reading addresses at a speed lower than a speed for writing the audio signals into the memory. It is determined whether an amount of audio signals stored in the memory and not yet read therefrom is increasing. The write addresses are then updated when the amount of audio signals not yet read is increasing. When small signals levels of which are lower than a reference level are detected among the audio signals, updating of the write addresses of the small signals may be halted.
