Problems solved by technology

And for these audios, an audio encoder needs to be added in the synthesis of multi-audio programs. If there are differences in the algorithm of the audio encoders, there will be large differences in the volume of different audios of the same program, and the quality of so many audio programs will be affected. Relatively poor

Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] see figure 1 , in one embodiment, a method for balancing multi-audio volume is provided. The method includes:

[0038] Step 101, acquire multiple channels of audio data.

[0039] Specifically, synthesizing a multi-audio program needs to input multiple channels of audio data from multiple audio sources. Its form can be but not limited to one channel of audio and video data and multiple channels of pure audio data, and the final synthesized multi-audio program includes one channel of video data and multiple channels of audio data.

[0040] In one embodiment, when a CVBS analog audio and...

Abstract

The invention discloses a method for balancing multi-audio volumes. The method comprises steps that, multi-path audio data is acquired; a mean volume value corresponding to the multi-path audio data is determined, a first zooming coefficient for zooming the multi-path audio data to one same volume benchmark is calculated; a second zooming coefficient corresponding to the multi-path audio data is determined according to an audio coder corresponding to the multi-path audio data, the second zooming coefficient is a coefficient for zooming one same input audio volume through different audio coders into one same volume benchmark; according to the first zooming coefficient and the second zooming coefficient, the multi-path audio data is coded; the coded multi-path audio data is synthesized to be a multi-audio program. Through the method, zooming processing on different audios in a multi-audio program can be realized, volume balance is realized, and quality of multi-audio programs can be improved.

Description

technical field [0001] The invention relates to the technical field of audio and video codec processing, in particular to a method and device for balancing multi-audio volumes. Background technique [0002] At present, the demand for multi-audio programs is extensive. For example, there are more and more forms of TV programs in the media industry. In the fierce competition, the production methods of programs have undergone great changes. Early multi-track audio and video recording plus post-editing synthesis is becoming more and more common, and has made a qualitative leap in TV quality. [0003] A multi-audio program contains different audio, which can itself vary in volume. And for these audios, audio encoders need to be added in the synthesis of multi-audio programs. If there are differences in the algorithm of audio encoders, different audios of the same program will have large differences in volume, and the quality of so many audio programs will be affected. Relativel...
