Problems solved by technology

However, in practical applications, even if there are more than two audio output modules in the electronic device, the audio processing unit of the electronic device only supports the stereo format, resulting in a situation where the sound field deviation is prone to occur when playing multi-channel audio. Damaged, reducing user experience

Embodiment Construction

[0085] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices consistent with aspects of the present disclosure as recited in the appended claims.

[0086] In the related art, since electronic devices are all based on stereo speakers, multi-channel audio signals with more than two channels will be down-mixed into stereo audio signals (ie, two-channel audio signals). As shown in Table 1, Table 1 is a mapping table for converting a multi-channel audio signal into a two-channel audio signal.

[0087] Table 1 Mapping table for converting multi-channe...

Abstract

The invention relates to a multi-channel signal conversion method and device and a storage medium, the method is applied to electronic equipment comprising a plurality of audio output modules, and the method comprises the following steps: obtaining the number of channels of an input first audio signal; if the sound channel number of the first audio signal is not the preset sound channel number, converting the first audio signal into a second audio signal with the preset sound channel number; and outputting audio signals of different sound channels of the second audio signal by using different audio output modules.

Description

technical field [0001] The present disclosure relates to the technical field of signal processing, and in particular to a multi-channel signal conversion method, device and storage medium. Background technique [0002] At present, most handheld electronic devices are limited by the number of audio output modules, and they can only support the two-channel format of stereo. Even if the audio source is multi-channel audio, usually, multi-channel audio refers to more than Two-channel audio, such as 5.1 multi-channel audio (that is, 6-channel audio) refers to a system with 5 basic channels (including left channel, center channel, right channel, left surround channel and right surround channel) channel) and a surround sound system with a subwoofer (Low Frequency Effects, LFE) channel; it is also necessary to compress the multi-channel audio to two-channel audio before playing. [0003] With the improvement of users' demands on the sound quality of handheld electronic devices, ele...
