Repeating this way, there will be two results, one is that there is a very serious echo, and the other is that after the signal is continuously superimposed, the power does not converge to a fixed value but diverges, exceeding the undistorted amplification limit of the amplifier, and finally becomes For monotones like rectangular waves (sharp howling), this function is useless

Embodiment 1
[0055] With the great improvement in the performance of personal computers and mobile phones and the popularization of broadband Internet, in recent years, it has been able to meet the one-stop service needs of real-time audio and video collection, encoding, and transmission, thus giving birth to webcasting. Webcasting is an application that realizes multimedia audio and video live broadcasting through the Internet. It collects original audio and video through terminal equipment and performs necessary encoding and packaging, and then transmits the data to the server in real time with a predefined protocol, and the server Complete real-time forwarding to the audience to achieve. Compared with traditional analog TV or digital TV applications, webcast has the advantages of widespread equipment, low threshold, and simple operation. An anchor who has a live broadcast room on a live broadcast platform can start a live broadcast on the live broadcast platform only through a personal ...

The invention relates to a microphone connection silencing method and system for live broadcast and a storage medium, and belongs to the technical field of the Internet. The method comprises the stepsthat a live broadcast end receives an audio signal sent by a microphone connection object and samples the audio signal to obtain a microphone connection sampling signal, the local audio signal is sampled to obtain a local sampling signal, the microphone connection sampling signal and the local sampling signal are mixed, sound channel dimension reduction is performed to obtain a single-sound-channel signal, and the single-sound-channel signal is sent to the microphone connection object. The system comprises a local live broadcast terminal used for sampling and receiving a local audio signal and an audio signal sent by the microphone connection object and sending the two signals to the microphone connection object after mixing and dimension reduction, a microphone connection terminal used for sending an audio signal to the local live broadcast terminal and receiving a monaural signal sent by the local live broadcast terminal, and a storage medium containing a computer program, wherein when the computer program is executed by a processor, the microphone connection silencing method for live broadcast is realized. Compared with the prior art, the method has the advantages of no echo, good microphone connection effect and the like.
Description
technical field [0001] The present invention relates to the field of Internet technologies, in particular to the field of live broadcasting, and specifically refers to a method, system and storage medium for connecting microphones and eliminating noise for live broadcasting.
