Embodiment 1
[0036] The present disclosure provides an audio channel metadata in a three-dimensional audio model, and describes it in detail.
[0037] The channel-based audio type used in the prior art is a method of directly transmitting the audio signal of each channel to each corresponding speaker without any signal modification. For example, mono, stereo, surround 5.1, surround 7.1, and surround 22.2 are all channel-based audio formats, with each channel being fed to a single speaker. Although channel-based audio types are used in the prior art, adding corresponding audio channel metadata to channel-based audio types can make audio processing easier. By marking each channel with a suitable identifier, you can Make sure the audio is pointing to the correct speakers.
[0038] An audio channel format represents a single sequence of audio samples on which certain operations can be performed, such as rendering the movement of objects in a scene. Embodiments of the present disclosure use a...
Embodiment 2
[0064] The present disclosure also provides a method embodiment inherited from the above embodiment, which is used for the generation method of audio package 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.
[0065] A method for generating audio channel metadata, such as figure 2 shown, including the following steps:
[0066] Step S110, generating audio channel metadata in response to the user's setting operation on the audio channel metadata, the audio channel metadata including:
[0067] Attribute area, including audio channel name, audio channel identification and audio channel type description information;
[0068] The sub-element area includes at least one audio block format and audio cutoff frequency information for indicating the time domain division of the audio channel, wherein the audio block format includes an audio block identifier and a scene ...
Embodiment 3
[0079] 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.
[0080] As a computer-readable storage medium, the memory 31 can ...
