    摘要: The present invention provides an audio processing device that appropriately suppresses echo generated in a stereophonic audio output. The audio processing device includes: means for generating a first artificial linear echo signal and a second artificial linear echo signal that are estimated to be generated by first audio and second audio travelling to audio input means; means for suppressing a linear echo signal mixed to an input audio signal based on the first artificial linear echo signal and the second artificial linear echo signal: means for estimating a non-linear echo signal based on the first artificial linear echo signal and the second artificial linear echo signal; and means for suppressing the non-linear echo signal.
