Problems solved by technology

At present, the 3D audio processing of online audio services is usually implemented locally on the terminal player. Due to the diversity of terminal technologies and hardware conditions and the different levels of support for 3D audio processing, a unified implementation effect cannot be achieved on each terminal.
There is no uniform implementation

example 1

[0049] NGINX is a high-performance HTTP server, which is characterized by less memory and strong concurrency. At the same time, the request processing process is divided into multiple stages. Each stage defines clear execution semantics according to the processing timing, and it is easy to intervene in the request processing process. Module development.

[0050] The following is based on NGINX for three-dimensional audio processing, the specific process is as follows:

[0051] (1) MP3 files that provide online audio services are placed in the root directory of NGINX, such as: content_1.mp3, content_2.mp3;

[0052] (2) Add the videopanner command under the configuration command of "location / " of NGINX to start the three-dimensional audio processing;

[0053] (3) start the NGINX server; visit the online audio service page that contains the page player processing flow, usually, the page player processing flow is included in a js file;

[0054] (4) After the page is loaded, the pa...

Abstract

The invention provides a three-dimensional sound effect online processing method based on an HTTP server. The method comprises the following steps: 1) after receiving an audio processing instruction, a page player assembles acquired data into a new URL and makes a request to the HTTP server; 2) the HTTP server loads the three-dimensional sound processing into a HTTP server request processing chain in module mode, captures a URL data request with a 3D sound parameter, performs the audio transformation processing on the audio data, and returns the processed audio data to the page player; and 3) the page player plays the audio. The method utilizes the concurrent processing capability of the general HTTP server to realize the real-time online three-dimensional sound processing of the audio data, and avoids the difference of terminal conditions, and provides the user with a unified service experience.

Description

technical field [0001] The invention relates to audio media service technology, in particular to an HTTP server-based online processing method for three-dimensional audio effects. Background technique [0002] With the development of the Internet and terminal technology, more and more online audio services have begun to appear. At present, the 3D audio processing of online audio services is usually implemented locally on the terminal player. Due to the diversity of terminal technologies and hardware conditions and the different levels of support for 3D audio processing, a unified implementation effect cannot be achieved on each terminal. There is no uniform implementation. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects still existing in the three-dimensional sound effect processing of the current online audio service, utilize the existing system of the online audio service, propose a kind of three-dimensi...
