    • An inter-channel level difference processing method and apparatus are disclosed, relate to the field of stereo audio technologies, are applicable to inter-channel level difference processing, and can ensure quality of decoded stereo audio in a case that a signal changes quickly or in a case of packet loss, and implement low bit-rate transmission of a stereo audio signal. A stereo audio signal is received, and the stereo audio signal is parsed frame by frame, to obtain an ICLD of each sub-band of each subframe of each frame of the stereo audio signal (101); a sum of absolute values of the ICLDs of each subframe of any frame of the stereo audio signal is calculated (102); and when an absolute value of a difference between the sums of the absolute values of the ICLDs of each two subframes of the any frame is less than a preset threshold, a weighted ICLD value of each sub-band of the any frame is calculated in a first weighting manner (103); or otherwise, a weighted ICLD value of each sub-band of the any frame is calculated in a second weighting manner (104).

    • A directivity adjustment device that maintains a constant direct-to-reverberant ratio based on the detected location of a listener in relation to the speaker array is described. The directivity adjustment device may include a distance estimator, a directivity compensator, and an array processor. The distance estimator detects the distance between the speaker array and the listener. Based on this detected distance, the directivity compensator calculates a directivity index form a beam produced by the speaker array that maintains a predefined direct-to-reverberant sound energy ratio. The array processor receives the calculated directivity index and processes each channel of a piece of sound program content to produce a set of audio signals that drive one or more of the transducers in the speaker array to generate a beam pattern with the calculated directivity index.
