    • A stereophonic image may be enhanced by splitting the left and right input audio signals into a plurality of left and right output signals in a plurality of audio frequency bands and then generating left and right output audio signals from the left and right output signals based on the magnitude of the differences between corresponding left and right output signals and also based upon the absolute magnitude of the left and right input audio signals themselves. In particular, a stereophonic image enhancement device according to the invention processes a left input signal and a right input signal using a first spectrum analyzer and a second spectrum analyzer which output a plurality of left output signals and right output signals corresponding to a plurality of frequency bands in response to the corresponding left input signal and right input signal. A table lookup signal is responsive to the plurality of left output signals and to the plurality of right output signals to output a plurality of left output signal pairs and a plurality of right output signal pairs. A first and second adder are responsive to the plurality of left output signal pairs and right output signal pairs respectively to add the output signal pairs and produce final left output signals and right output signals respectively.
    • 可以通过将左右输入音频信号分割成多个音频频带中的多个左右输出信号,然后基于左右输出信号从左和右输出信号生成立体声图像 相应的左右输出信号之间的差异幅度也是基于左右输入音频信号本身的绝对幅度。 特别地,根据本发明的立体声图像增强装置使用第一频谱分析仪和第二频谱分析仪处理左输入信号和右输入信号,第二频谱分析仪输出多个左输出信号和对应于多个频率的右输出信号 响应于相应的左输入信号和右输入信号的频带。 表查找信号响应于多个左输出信号和多个右输出信号以输出多个左输出信号对和多个右输出信号对。 第一和第二加法器分别响应于多个左输出信号对和右输出信号对,以分别输出输出信号对并产生最终左输出信号和右输出信号。
