Audio data mixing method and device

Abstract

The invention discloses an audio data mixing method and device. The method comprises the steps that terminals applying for speaking collect user voice, generate audio data packets, and send applying signals to a host; after receiving all the applying signals sent by the terminals applying for speaking, the host sends license instructions to the terminals applying for speaking simultaneously; the terminals applying for speaking receive the license instructions, and send the audio data packets to the host; the host receives multiple paths of audio data packets from all the terminals applying for speaking, and performs mixing; when mixing is required, the host sends the license instruction to every terminal applying for speaking, and all the terminals applying for speaking send the audio data to the host synchronously after receiving the license instructions. Thus the phenomenon of larger delay due to the influence of the network transmission status during the receiving of the audio data in the existing mixing process can be effectively avoided.

Description

technical field [0001] The invention relates to the field of audio data transmission methods and equipment, in particular to an audio data mixing method and device. Background technique [0002] The digital audio conferencing system uses computer, digital and network technology to network various systems, including the audio data transmission system of the host computer and multiple terminals. All digital signals are transmitted on the line, which not only greatly improves the sound quality, but also improves the system reliability. , And it fundamentally eliminates the defects of interference, distortion, crosstalk and system instability in general conference systems, so that every participant can hear stable and pure voices. [0003] When the existing digital audio conferencing system transmits audio data, the host sends multiple channels of audio data to each terminal, and when mixing the multiple channels of audio data, it simply mixes the received audio data. Due to th...

Problems solved by technology

[0003] When the existing digital audio conferencing system transmits audio data, the host sends multiple channels of audio data to each terminal, and when mixing the multiple channels of audio data, it simply mixes the received audio data. Due to the delay in the TCP / IP protocol itself, some data will be delayed, and some data will have a queue that is too long, which will cause delays in the voice of some unit machines.
