METHOD AND DEVICE FOR PROCESSING AUDIO SIGNAL

摘要

A method and device for processing an audio signal, which enhance front sound source characteristics in left and right channel output signals, thereby reducing the possibility that a user incorrectly judges a front sound source to be from the rear side. The method comprises: receiving a left input channel signal, a middle channel signal and a right input channel signal, which are acquired by binaural audio acquisition equipment; determining a sound source azimuth angle between a sound source and a head mould of the binaural audio acquisition equipment; convolving the middle channel signal with an exaggerated left ear head-related impulse response (HRIR) corresponding to the sound source azimuth angle, thereby acquiring an auxiliary left channel signal; convolving the middle channel signal with an exaggerated right ear HRIR corresponding to the sound source azimuth angle, thereby obtaining an auxiliary right channel signal; and acquiring a left output channel signal by utilizing the left input channel signal and the auxiliary left channel signal, and obtaining a right output channel signal by utilizing the right input channel signal and the auxiliary right channel signal.
