Embodiment Construction

[0075] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0076] figure 1 It is a flowchart of an audio mixing method shown in an exemplary embodiment of the present disclosure, and the method may be applied to a terminal, for example, a sound mixing device. Alternatively, the method can be applied in the cloud, for example, to a server for audio mixing processing.

[0077] Such as figure 1 As shown, the method may include the following steps.

[0078] In S101, multiple channels of PCM audio data are acquired, and configuration parameters of each channel of PCM audio data are the same.

[0079] Among them, PCM (Pulse Code Modulation) audio data is an uncompressed audio sample data stream, and one sample point da...

Abstract

The disclosure relates to an audio mixing method and device, a storage medium and electronic equipment. The method comprises the steps of: acquiring multiple paths of PCM audio data, wherein each pathof PCM audio data is the same in configuration parameter; and carrying out mixing processing on the multiple paths of PCM audio data to obtain a path of mixed audio data, wherein the mixed audio dataincludes partial audio bytes in each path of PCM audio data. Therefore, a problem that after audio mixing, sound spills over to be distorted or the sound is big and small is solved, so that the soundafter audio mixing is natural, clear and smooth. Meanwhile, the audio mixing method does not need to carry out addition, subtraction, multiplication and division operations on the audio data, so thatthe audio mixing method provided by the disclosure is simple and easy to implement, efficiency of audio mixing is improved and universality is higher.

Description

technical field [0001] The present disclosure relates to the technical field of audio processing, and in particular, to an audio mixing method, device, storage medium and electronic equipment. Background technique [0002] Audio mixing is to combine multiple channels of audio into one audio. For example, add a background music to the original audio of a speech. In the prior art, most audio mixing methods are based on superimposing two audios, some are linear superposition, some are weighted superposition, and some are linear plus nonlinear superposition. However, the amplitude of the audio superimposed by these methods will exceed the maximum value at some points in time, causing the sound after mixing to overflow and distort, or the sound to fluctuate. Contents of the invention [0003] In order to solve the problems in related technologies, the present disclosure provides an audio mixing method, device, storage medium and electronic equipment. [0004] In order to ach...
