Embodiment 1

[0036] This embodiment provides an audio mixing method based on the command and dispatch system, which can meet the high-quality automatic sound mixing requirements of the 256K command high-fidelity dispatch system and reduce the dependence on professionals. Such as figure 1 As shown, the audio mixing method of this embodiment specifically includes:

[0037] Step S1: Collect training samples for neural network training to construct a neural network model.

[0038] Collect several groups of mixed sound data as training samples, among which the mixed sound data used as training samples is 256k high-fidelity scheduling voice audio data, the sampled value of the mixed sound data is used as input, and the sampled value after mixing is used as output, and the network Train to build a neural network model. The neural network has memory, parameter sharing and Turing completeness, so it has certain advantages in learning the nonlinear characteristics of the sequence.

[0039] Among ...

Embodiment 2

[0047] This embodiment provides an audio mixing device based on the command and dispatch system. The audio mixing device can directly process the audio data of the multi-channel 256k high-fidelity command and dispatch system by using a neural network, and can realize the high-fidelity audio recording conveniently and quickly. The mixing sound has high practical value. Such as Figure 4 As shown, the audio mixing device of this embodiment specifically includes at least several important parts of a neural network training module 1 , a normalization processing module 2 and a processor module 3 .

[0048] Wherein, the neural network training module 1 is used for training the network to construct a neural network model by taking the sampling values ​​of each group of audio data of the training samples as input and taking the sampling values ​​of the audio data after mixing as output.

[0049] And described normalization processing module 2 is used for using the sound bit number of...

Embodiment 3

[0054] The present invention further discloses a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the audio mixing method based on the 256k high-fidelity command and dispatch system described in Embodiment 1 is realized.

Abstract

The invention discloses an audio mixing method and device based on a command and dispatch system and a storage medium. The audio mixing method comprises the steps: S1, collecting training samples forneural network training to construct a neural network model; S2, acquiring audio data of at least two groups of scheduling voices, representing sampling values of the audio data by using sound digitsof the audio data, and normalizing the sampling values of the audio data of all scheduling voices; and S3, inputting the normalized sampling value into the neural network model to obtain audio data ofthe scheduling voice after audio mixing. According to the invention, the audio data of the multipath 256k high-fidelity command and dispatch system can be directly processed, and the audio mixing ofthe high-fidelity audio can be conveniently and quickly realized by setting the neural network parameters and the audio mixing weight, so that the method has a very high practical value; and the method is relatively low in calculation complexity, and plays an important role in reducing hardware requirements and improving voice equalization quality.

Description

technical field [0001] The invention relates to the field of multimedia application technology, in particular to an audio mixing method, device and storage medium based on a 256k high-fidelity command and dispatch system. Background technique [0002] At present, with the development of computer science and information science, digital processing technology emerges as the times require and develops rapidly. Sound mixing is an audio processing method that mixes various audio signals and then outputs them. In the process of mixing multiple channels of input and one output, it can also adjust the frequency, dynamics, sound quality, positioning, The reverb and soundstage can be adjusted to suit various mixing needs. [0003] However, in the existing 256K high-fidelity command and dispatch system, the mixing of high-quality requirements generally requires professionals to manually participate in the entire multi-channel audio processing process. The current automatic mixing is c...
