Problems solved by technology

As a result, the inter-frame stability of the clustering process is relatively low, which is likely to cause auditory artifacts when rendering audio object classes

Embodiment Construction

[0017] The principles of the invention will be described below with reference to several example 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.

[0018] As mentioned above, in known audio object clustering schemes, the assignment of objects to classes is sometimes unstable. Stable assignment here means that audio objects (at least for those static objects) are consistently assigned to cluster centers with the same location. For audio objects with fixed locations, the assignment of objects to classes is usually determined by the location of the chosen cluster centers. If the location of the center is relatively stable, the assignment of objects to classes will also be relatively stable. On the contrary, if the cluster centers move or even jump from one loc...

Abstract

The embodiment of the present invention involves the audio object cluster that changes the time of the audio object.Provide a time change to use audio objects in audio object clusters.This method includes at least one clip that obtains the sound track associated with the audio object, which contains at least one clip containing the audio object; at least one attribute of the audio object is estimatedThe duration of a fragment; and at least part of the change based on the estimated changes, adjust the contribution of the audio object to the cluster center in the audio object cluster.The corresponding system and computer program products have also been released.

Description

technical field [0001] The present invention relates generally to audio object clustering, and more particularly to methods and systems for using temporal variation of audio objects in audio object clustering. Background technique [0002] Traditionally, audio content is created and stored in a channel based format. The term "audio channel" or "channel" as used herein refers to audio content, usually having a predefined physical location. For example, stereo, surround 5.1, surround 7.1, etc. are all channel-based formats for audio content. Recently, many traditional multi-channel systems have been extended to support a new format that includes both channels and audio objects. The term "audio object" or simply "object" as used herein refers to an individual audio element that exists in a sound field for a certain duration. An audio object can be dynamic or static. For example, an audio object may be a person, an animal, or any other element capable of acting as a sound so...
