Abstract: PURPOSE: A method for encoding/decoding an integrated voice/music signal and a device thereof are provided to effectively select an internal module according to a feature of an input signal, thereby providing superior sound quality for both a voice signal and a music signal at various bit rates. CONSTITUTION: An input signal analyzing unit(110) analyzes a feature of an input signal. When the input signal is a music feature signal, a first conversion encoding unit(120) converts a domain of the input signal into a frequency domain.

When the input signal is a voice feature signal, an LPC(Linear Predictive Coding) encoding unit(130) encodes the input signal based on LPC. A bit stream generating unit(140) generates a bit stream using output signals of the first conversion encoding unit and the LPC encoding unit.
