PURPOSE: An apparatus for transmitting and reproducing digital audio signal is provided to improve a level of an output digital signal and to prevent a multi-bit digital audio signal from clipping in full bit level. CONSTITUTION: A transmiting apparatus and a reproducing apparatus comprising a converter for converting an input one-bit digital signal into a multi-bit signal while effecting down-sampling of a sampling frequency. An one-bit digital signal that could develop an overflow(clip) depending on its modulation degree is attenuated at a stage upstream of the input of the converter, and is amplified at a stage downstream of the converter to avert a clipper state between the stages.
