Abstract

The embodiment of the invention discloses an audio output method, an audio output device and a multimedia server. The audio output method comprises the following steps: analyzing multiple paths of audio sources to obtain multiple audio source parameter groups in one-to-one correspondence with the multiple paths of audio sources; acquiring an audio output configuration parameter group; decoding the audio frames of the multi-channel audio sources to obtain multi-frame audio data in one-to-one correspondence with the multi-channel audio sources; according to the plurality of audio source parameter groups and the audio output configuration parameter group, processing the multi-frame audio data to obtain multi-frame processed audio data in one-to-one correspondence with the plurality of paths of audio sources; and outputting the multi-frame processed audio data. According to the invention, multiple audio source parameter groups corresponding to multiple paths of audio sources can perform original sound playing at the same time, and the playing sound quality of the multiple paths of audio sources is ensured.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an audio output method, an audio output device and a multimedia server. Background technique [0002] In the performing arts scene, it often happens that a program contains multiple materials such as audio, video, etc., and the multiple audio and video materials contained in the same program usually have audio data. During the playback of the program, it is necessary to ensure that each The material (audio, video) can be played according to the sound effect when it is recorded and saved. However, in the case that the audio source parameters of each of the multiple audio sources are different, it is difficult to guarantee the sound quality of the audio sources when these multiple audio sources are played simultaneously. Contents of the invention [0003] The main purpose of the present invention is to provide an audio output method, an audio output device, and a multimedi...
