Abstract

The present application discloses an audio processing method, device, device and storage medium, which belong to the technical field of audio. The method includes: acquiring a two-channel audio signal to be processed, where the two-channel audio signal includes a left-channel signal and a right-channel signal; determining a single-channel frequency domain signal according to the left-channel signal and the right-channel signal; The channel signal and the right channel signal are used to determine the sound field information; according to the sound field information, the direction information of the frequency points in the single-channel frequency domain signal is determined; the direction information of the frequency points in the single-channel frequency domain signal is classified to obtain multiple A mask sequence of channels, one mask sequence corresponds to one channel, and each mask sequence is used to indicate that the corresponding channel includes the frequency domain signal situation corresponding to multiple frequency points in the single channel frequency domain signal; A sequence of masks and single-channel frequency-domain signals to determine multi-channel audio signals. The embodiments of the present application can reduce the correlation between frequency domain signals of different channels.

Description

technical field [0001] The present application relates to the field of audio technology, in particular to an audio processing method, device, equipment and storage medium. Background technique [0002] Multi-channel surround sound systems are widely used in film and television, broadcasting and other fields. However, many audios are produced by two-channel stereo systems. In order to obtain better auditory effects, the audio is often converted from two-channel audio signals to multi-channel channel audio signal. [0003] Currently, a two-channel audio signal can be converted into a multi-channel audio signal by using a transformation matrix. For example, a two-channel audio signal may be converted into a signal matrix, and the signal matrix may be converted to obtain a multi-channel audio signal. [0004] However, when the number of channels of a multi-channel audio signal is determined, different binaural audio signals are multiplied by the same transformation matrix to o...
