Abstract

The invention discloses a sound mixing method of live broadcast software, and aims at acquiring audio data sources of played accompaniment audios during sound mixing and performing sound mixing processing on the audio data sources and user audios collected by using microphones. The invention further provides a sound mixing device and system of the live broadcast software and a computer readable storage medium. Visibly, when sound mixing is carried out, the method does not collect audios outputted by speakers and perform echo cancellation as in the conventional sound mixing method, but directlyacquires audio data sources of played accompaniment audios, thereby solving the problem of relatively large noise when the audios output by the speakers are collection on one hand, and avoiding the problem of collecting audios of users connected with microphones in the acquisition process on the other hand, so that echo cancellation and background noise suppression do not need to be carried out on the accompaniment audios in the sound mixing process and then the quality of the sound mixed audios is enhanced.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a sound mixing method, device, system and computer-readable storage medium of live software. Background technique [0002] In the live broadcast scene where a personal computer is used for mic-linking, it is often necessary to mix the accompaniment audio and the audio of the current user, so as to push the mixed audio to the mic-linker. The traditional sound mixing solution is mainly to obtain the audio output from the computer speaker (the mix of the accompaniment audio and the mic audio) and the audio collected by the microphone; Perform 3A processing (i.e. AGC automatic gain compensation, ANS background noise suppression, AEC echo canceller), wherein, the audio output from the speaker is processed to obtain the accompaniment audio, and the audio collected by the microphone is processed to obtain the user audio; finally, the accompaniment audio is combined with the The user's ...
