Problems solved by technology

[0003] When adding multi-channel mixed audio to existing microphones, specific software needs to be used and the bandwidth of the network is extremely consumed, and because the audio data is not mixed into the microphone output, the microphone data obtained by other software on the system is still only external to the environment sound, resulting in poor multi-channel audio mixing from the microphone

Abstract

The invention discloses a processing method and device for mixing multiple channels of audios in microphone data, and relates to the technical field of audio and video processing, and the method comprises the steps: receiving and decoding an audio mixing request of a user, and obtaining to-be-mixed audio data; superposing the audio data to be mixed; calculating the output amplitude of the mixed audio sample data; judging the output amplitude and a preset amplitude, and adjusting the output amplitude to obtain basic mixed audio data; intercepting data output by the microphone as recording data; and carrying out mixing processing on the recording data and the basic mixed audio data to obtain target mixed audio data, and sending the target mixed audio data to a process. According to the embodiment of the invention, the mixed audio data is added into the microphone data, so that calling and use are facilitated, interference of other audios on the mixed audio is avoided, the mixing effect of the recording data and the multi-channel audios is improved, and the situation that the microphone data acquired by other software on the system only has external environment sound is avoided.

Description

technical field [0001] The present application relates to the technical field of audio and video processing, and in particular, to a method and device for processing mixed multi-channel audio in microphone data. Background technique [0002] Nowadays, multimedia services are widely used. Audio interaction is one of the important components in multimedia services. It is the most basic element of multimedia services. For multimedia services of video conferencing, packet loss and delay of voice data The problem of freezing is the difficulty of video conferencing, and the transmission of multi-channel audio and multiple endpoints sending data to each other at the same time will further increase the burden of network transmission. If the multi-channel audio is sent after mixing processing, it can reduce the burden of network transmission. . And with the development of communication technology, the use of webcasting and video conferencing is becoming more and more common, and it ...
