This application discloses a virtual stereo synthesis method and apparatus, where the method includes: acquiring at least one sound input signal on one side and at least one sound input signal on the other side; separately performing ratio processing on a preset head related transfer function HRTF left-ear component and a preset head related transfer function HRTF right-ear component of each sound input signal on the other side, to obtain a filtering function of each sound input signal on the other side; separately performing convolution filtering on each sound input signal on the other side and the filtering function of the sound input signal on the other side, to obtain the filtered signal on the other side; and synthesizing all of the sound input signals on the one side and all of the filtered signals on the other side into a virtual stereo signal. In the foregoing manner, this application can alleviate a coloration effect, and reduce calculation complexity. |
