A digital audio playing apparatus and method can add multiple mixing and various sound effects to the background music stored in various storage devices, audio data including accompaniment or the voice of user delivered from an external input device such as a microphone. A digital audio playing apparatus for mixing analog audio data inputted from a microphone part and compressed audio data stored in a storage and adding the sound effect through signal processing includes an ADC(Analog to Digital Converter) part(220) converting analog audio data into digital audio data; a first processor(230) multiple-recovering a plurality of compressed audio data to produce a plurality of recovery audio data; and a second processor(240) producing second signal processing audio data by operating a second signal processing unit to perform second signal processing of the digital audio data, producing mixed audio data by mixing the second signal processing audio data with the recovery audio data, and encoding the mixed audio data and storing it in a storage unit(270) or delivering it to a speaker unit(252) through a DAC(Digital to Analog Converter) part(250).
