This is invention about the limiter which disappearance of low swing signal is a little. The signal of a part going over amplitude limiting value are all lost in conventional limiter. In this invention limiter, swing part going over limiting value is lost too, but small level signal of frequency high relatively to exist in the lost part at the same time isn't lost much. You can design the small noise hearing aid, the small power and big sound audio amplifier, the sound recorder that both parties of the near sound and distant sound are recorded distinctly, the soundproofing apparatus that the small sound is heard normally, the small sidetone telephone, the transmitter that it is possible for communication in transmission medium of low rate, and etc., if use this invention limiter.
