Embodiment Construction

[0020] The principle and spirit of the present invention will be described below with reference to several exemplary embodiments shown in the accompanying drawings. It should be understood that these embodiments are described only to enable those skilled in the art to better understand and implement the present invention, but not to limit the scope of the present invention in any way.

[0021] first reference figure 1 , which shows a schematic diagram of adaptive audio content generation according to an embodiment of the present invention. According to an embodiment of the present invention, the source audio content 101 to be processed adopts a traditional channel-based format, such as stereo, surround 5.1, surround 7.1 and other formats. In particular, according to embodiments of the present invention, the source audio content 101 may be any type of final mix, or a set of audio tracks that may be processed separately before being merged into a final mix of conventional stere...

Abstract

The embodiment of the invention relates to self-adaptive audio frequency content generation and particularly discloses a self-adaptive audio frequency content generating method. The self-adaptive audio frequency content generating method comprises the steps of extracting at least one audio object from source audio frequency contents based on a sound track and generating at least a part of audio frequency contents based on at least one audio object. The invention further discloses a corresponding system and a computer program product.

Description

technical field [0001] The present invention relates generally to audio signal processing, and more particularly to adaptive audio content generation. Background technique [0002] Current audio content is usually generated and stored in a channel-based format. For example, stereo, surround 5.1, and surround 7.1 are all widely used channel-based audio content formats. With the continuous development of multimedia technology, multimedia digital content, such as three-dimensional (3D) movies and television, is becoming increasingly popular. However, traditional channel-based audio formats are often difficult to effectively create immersive and lifelike audio content. Therefore, it is expected that multi-channel audio systems will be expanded accordingly to create a more immersive stereo sound field. One of the important ways to achieve this goal is to use adaptive (adaptive) audio content. [0003] Compared with traditional channel-based audio content, adaptive audio conte...
