Problems solved by technology

It aims to solve the problem that the rendering function is set outside the integrated media block (IMB) in the prior art, resulting in the need to use an enhanced audio processing unit (EAPU) to re-decrypt, decode and forensically mark it to achieve real-time rendering, resulting in complicated real-time rendering steps. Waste of power resources, technical problems of poor synchronous sound effects

Abstract

The invention discloses a real-time sound processing system and a real-time sound processing method. The system comprises an integrated media unit and an audio equalization and delay unit. The integrated media unit is used for decrypting, decoding, rendering and forensic-marking a video and an audio. The audio equalization and delay unit is used for equalizing the audio processed by the integrated media unit. According to the invention, re-decryption and re-forensic-marking, which are caused by the fact that an enhancement audio processing unit (EAPU) outside the integrated media unit is placed in a rendering function, are reduced; the steps are simplified; power consumption is reduced; a theater does not need to re-purchase the enhancement audio processing unit (EAPU), and uses an audio processing unit (APU) to realize immersive 3D sound effect; and the theater cost is reduced.

Description

technical field [0001] The invention relates to the technical field of multimedia sound effects, in particular to a real-time sound effect processing system and a real-time sound effect processing method. Background technique [0002] With the rapid development of multimedia and the improvement of living standards, people have higher and higher requirements for movie sound effects. Movie sound effects have developed from monophonic to surround-channel applications, and audio content is based on channel-based audio. Formats are created and stored, with loudspeakers (or groups of loudspeakers) placed at different locations in the theater to add to the sound effects. Recently, three-dimensional (3D) movies have become more and more popular as the industry has grown. In order to create more immersive sound effects, many traditional channel-based audio formats have developed object-based audio formats, that is, audio formats now include channel-based and object-based audio forma...
