specific Embodiment approach

[0046] The core of the present invention is to provide an audio processing method, and a schematic flow chart of a specific implementation thereof is as follows figure 1 As shown, it is called the first specific implementation mode, including:

[0047] S101: Receive an original source signal and an original microphone signal.

[0048] The original source signal refers to the audio signal from the superior system, rather than the signal directly collected by the microphone, which may include local multimedia playback, digital audio and video sources such as HDMI, DP, Type-C, or AV, YUV, VGA, etc. Analog audio and video sources.

[0049] S102: Adjust volumes of the original source signal and the original microphone signal respectively according to preset volume adjustment information to obtain a quantitative source signal and a quantitative microphone signal.

[0050] The volume adjustment information may be a preset fixed value, or may be manually modified at any time.

[00...

Embodiment approach

[0081] As a preferred implementation manner, the receiving module 100 includes:

[0082] fixed source unit, used to confirm a single microphone signal source as the target signal source;

[0083] The split-source receiving unit is configured to receive the original source signal and volume adjustment information, and receive the original microphone signal from the target signal source.

[0084] As a preferred implementation manner, the sound mixing module 300 includes:

[0085] a premixing unit, configured to mix the quantitative source signal and the quantitative microphone signal to obtain a mixed signal;

[0086] The sound effect processing unit is configured to perform sound effect processing on the audio mixing signal to obtain the audio output signal.

[0087] As a preferred implementation manner, the sending module 400 includes:

[0088] a separation unit, configured to separate the audio output signal into multiple channels of data to obtain a plurality of separated...

Abstract

The invention discloses an audio processing method. The method comprises the following steps: receiving an original information source signal and an original microphone signal; respectively adjustingthe volumes of the original information source signal and the original microphone signal according to preset volume adjustment information to obtain a quantitative information source signal and a quantitative microphone signal; mixing the quantitative information source signal and the quantitative microphone signal to obtain an audio output signal; and sending the audio output signal to a broadcasting device to complete audio processing. According to the invention, the collected original information source signal and the original microphone signal are adjusted according to the volume adjustment information, the volume of the two signals reaches the preset value, and then the two signals after volume adjustment are mixed and sent, so that the volume of the signal source signal and the volume of the microphone signal are independently adjusted, and the universality is greatly improved. The invention further provides an audio processing device and equipment with the advantages and a computer readable storage medium.

Description

technical field [0001] The present invention relates to the field of audio processing, in particular to an audio processing method, device, equipment and computer-readable storage medium. Background technique [0002] With the development of society, in more and more application scenarios, it is necessary to collect human voice and system source sound and mix the two, such as the use of various products such as conference smart tablets, educational all-in-one machines, and enterprise smart screens. In the scene, it includes multiple audio inputs and multiple audio outputs. In the audio input channel, digital microphones and analog microphones are used to collect the sound of the environment where the display terminal is located. Other system sources such as HDMI, DP, VGA, AV, Type Audio input channels such as -C play the audio of the source device (such as a laptop), and what we have to do is to mix the two. [0003] Taking the educational all-in-one machine as an example, ...
