    • 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. The first conversion encoding unit encodes the converted input signal. 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.
    • 目的:提供一种用于对集成语音/音乐信号进行编码/解码的方法及其装置,以根据输入信号的特征有效地选择内部模块,从而为语音信号和音乐信号两者提供卓越的音质 各种比特率。 构成:输入信号分析单元(110)分析输入信号的特征。 当输入信号是音乐特征信号时,第一转换编码单元(120)将输入信号的域转换成频域。 第一转换编码单元对转换的输入信号进行编码。 当输入信号是语音特征信号时,LPC(线性预测编码)编码单元130根据LPC对输入信号进行编码。 比特流生成单元(140)使用第一转换编码单元和LPC编码单元的输出信号生成比特流。

    • PURPOSE: An apparatus for encoding and decoding integrated voice and audio signals is provided to combine a voice codec module with an audio codec module and selectively apply a codec module depending on a characteristic of an input signal, thereby showing excellent performance. CONSTITUTION: A module selecting unit(110) analyzes a characteristic of an input signal to select the first encoding module for encoding the first frame of an input signal. A voice encoding unit(130) encodes the input signal by selection of the module selecting unit to generate a voice bit string. An audio encoder(140) encodes the input signal by selection of the module selecting unit to generate an audio bit string. A bit stream generator(150) generates an output bit string from the audio encoder by selection of the module selecting unit.
