  • Patent number: 10939221
    Abstract: An audio processing method and an audio processing system are provided. In the audio processing method, an audio signal is first provided. Then, plural predetermined categories are provided. Then, a classification step is performed on the audio signal according to the predetermined categories. Thereafter, a transform step is performed on the audio signal to convert the audio signal into a frequency domain. Then, a panning step and a summing step are performed on amplitude signals of the audio signal to obtain a total amplitude signal. Thereafter, a separation step and a summing step are performed on phase signals of the audio signal to obtain a total phase signal. Then, an inverse transform step is performed on the total amplitude signal and the total phase signal to obtain an optimized audio signal in a time domain.
