The invention provides an audio extraction apparatus, a machine learning apparatus and an audio reproduction apparatus. A processor in the audio extraction apparatus performs a preprocessing operationto determine, for a stereo audio source including first channel audio data including an accompaniment sound and a vocal sound for a first channel and second channel audio data including an accompaniment sound and a vocal sound for a second channel, a difference between the first channel audio data and the second channel audio data to generate center cut audio data, and an audio extraction operation to input the first channel audio data, the second channel audio data and the center cut audio data to a trained machine learning model to extract any one of the accompaniment sound and the vocal sound. 音频提取装置、机器训练装置、卡拉OK装置。具有控制部(处理器)，执行：预处理，针对包含第一声道音频数据和第二声道音频数据的立体声音源，对所述第一声道音频数据和所述第二声道音频数据执行减法处理，生成中心剪切音频数据，所述第一声道音频数据包含用于第一声道的伴奏声音和声乐声音，所述第二声道音频数据包含用于第二声道的伴奏声音和声乐声音；以及音频提取处理，通过向训练后的机器训练模型输入所述第一声道音频数据、所述第二声道音频数据和所述中心剪切音频数
