    Abstract: A stereo signal encoding method includes determining a window length of an attenuation window based on an inter-channel time difference, determining a modified linear prediction analysis window based on the window length of the attenuation window, where values of at least some points from a point (L−sub_window_len) to a point (L−1) in the modified linear prediction analysis window are less than values of corresponding points from a point (L−sub_window_len) to a point (L−1) in an initial linear prediction analysis window, and the window length of the modified linear prediction analysis window is equal to a window length of the initial linear prediction analysis window, and performing linear prediction analysis on a to-be-processed sound channel signal based on the modified linear prediction analysis window.

    Abstract: In an audio signal processing method, an audio signal processing apparatus receives an audio signal that meets a screening condition at a listening position, where the screening condition includes one or more of the following conditions: a volume at the listening position being greater than or equal to a volume threshold, a listening distance between the sound source and the listening position being less than or equal to a preset listening distance, or the sound source being in a range corresponding to a listening orientation. The apparatus decodes the audio signal meeting the screening condition to obtain a decoded audio signal. The apparatus then renders the decoded signal based on a sound channel transfer function in a playing device to obtain an output signal.
