Abstract
Embodiments of the present invention relate to adaptive audio content generation. Specifically, a method for generating adaptive audio content is provided. The method comprises extracting at least one audio object from channel-based source audio content, and generating the adaptive audio content at least partially based on the at least one audio object. Corresponding system and computer program product are also disclosed.
Claims21
A method for generating adaptive audio content, the method comprising:
- extracting at least one audio object from channel-based source audio content, wherein extracting the at least one audio object comprises:
- decomposing the source audio content into a directional audio signal and a diffusive audio signal, wherein decomposing the source audio content comprises performing signal component decomposition on the source audio content and calculating a probability for diffusivity by analyzing the decomposed signal components;
- and
- extracting the at least one audio object from the directional audio signal;
- and
- generating the adaptive audio content at least partially based on the at least one audio object.
A system for generating adaptive audio content, the system comprising:
- an audio object extractor configured to extract at least one audio object from channel-based source audio content, wherein extracting the at least one audio object comprises:
- decomposing the source audio content into a directional audio signal and a diffusive audio signal, wherein decomposing the source audio content comprises performing signal component decomposition on the source audio content and calculating a probability for diffusivity by analyzing the decomposed signal components;
- and
- extracting the at least one audio object from the directional audio signal;
- and
- an adaptive audio generator configured to generate the adaptive audio content at least partially based on the at least one audio object.
