Embodiment 1

[0038] This disclosure provides an audio stream metadata in a 3D audio model and describes it in detail.

[0039] Streams, which are combinations of audio tracks required to render passes, objects, higher-order ambience components, or packages. The relationship between the audio track format set and the audio channel format set, or the relationship between the audio track format set and the audio package format can be established through the audio stream format element.

[0040] The audio stream metadata includes an attribute area and a sub-element area.

[0041] Attribute area, including audio stream name, audio stream identifier and audio stream format description information;

[0042] The sub-element area includes one of audio channel format reference information and audio package format reference information, and also includes audio track format reference information.

[0043] Among them, the attribute area includes the general definition of audio stream metadata. The a...

Embodiment 2

[0061] The present disclosure also provides a method embodiment inherited from the above embodiment, which is used to generate audio stream metadata. The explanation based on the same name meaning is the same as the above embodiment, and has the same technical effect as the above embodiment. Here No longer.

[0062] A method for generating audio stream metadata, such as figure 2 shown, including the following steps:

[0063] Step S110, generating audio stream metadata in response to the user's setting operation on the audio stream metadata, the audio stream metadata including:

[0064] Attribute area, including audio stream name, audio stream identifier and audio stream format description information;

[0065] The sub-element area includes one of audio channel format reference information and audio package format reference information, and also includes audio track format reference information.

[0066] The user's setting operation for the audio stream metadata may be an o...

Embodiment 3

[0078] image 3 A schematic structural diagram of an electronic device provided by Embodiment 3 of the present disclosure. Such as image 3 As shown, the electronic device includes: a processor 30 , a memory 31 , an input device 32 and an output device 33 . The number of processors 30 in the electronic device can be one or more, image 3 A processor 30 is taken as an example. The number of memory 31 in the electronic device can be one or more, image 3 Take a memory 31 as an example. The processor 30, the memory 31, the input device 32 and the output device 33 of the electronic device can be connected by bus or other methods, image 3 Take connection via bus as an example. The electronic device may be a computer, a server, and the like. Embodiments of the present disclosure are described in detail by using an electronic device as a server, and the server may be an independent server or a cluster server.

[0079] As a computer-readable storage medium, the memory 31 can ...

Abstract

The invention relates to audio stream metadata, an audio stream metadata generation method, electronic equipment and a storage medium. The audio stream metadata comprises an attribute area which comprises an audio stream name, an audio stream identifier and audio stream format description information; and the sub-element region comprises one of audio channel format reference information and audio packet format reference information, and further comprises audio track format reference information. The audio data can realize three-dimensional sound reproduction in the space during rendering, so that the quality of a sound scene is improved.

Description

technical field [0001] The present disclosure relates to the technical field of audio processing, and in particular to an audio stream metadata and a generating method, an electronic device and a storage medium. Background technique [0002] As technology develops, audio becomes more and more complex. From the early monophonic audio to stereo, the focus of work is also on the correct processing of the left and right channels. But with the advent of surround sound, the process started to get complicated. The surround 5.1 speaker system sorts and constrains multiple channels, and then the surround 6.1 speaker system, surround 7.1 speaker system, etc. make the audio processing ever-changing, and transmit the correct signal to the appropriate speaker to form an interrelated effect. Therefore, as sound becomes more immersive and interactive, the complexity of audio processing increases significantly. [0003] An audio channel (or channel) refers to mutually independent audio s...
