Abstract

Provided are a high-quality audio player for an Android operating system-based portable electronic device and a method therefor. A high-quality audio player for an Android operating system-based portable electronic device according to an embodiment of the present invention comprises: a first processor which is a main processor of a portable electronic device, is operated by the Android operating system, controls functions of the portable electronic device, and plays back a sound source having a format supported by the Android operating system; and a second processor for playing back a high-quality sound source which is provided using a higher sampling rate and a higher bit depth than media formats supported by the Android operating system. Here, when a high-quality sound source is played back, the first processor places restrictions on some of the functions of the portable electronic device supported by the Android operating system and determines the time to output a digital signal of the high-quality sound source, according to the restricted functions, so as to reduce an error in the time to output the digital signal, and the second processor regularly adjusts an output signal from the first processor at periods corresponding to the sampling rate of the high-quality sound source, and outputs the same in real time.
