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.

An device includes an audio output unit, a first audio input unit, a second audio input unit that are disposed in a position closer to the audio output unit than the first audio input unit, a unit for outputting a combined signal of which audio signals from the first and second audio input unit are combined so as forming directivity in which sensitivity in a direction of the audio output unit is low when viewed from the first and second audio input units, a unit for generating artificial echo corresponding to an echo component mixed in the audio inputted to the first audio input unit, and a unit for performing an echo suppression process to the combined signal by using the artificial echo.
