Abstract
An audio system that is configured to convert a plurality of audio input channels to object-based audio, and a related computer program product. Correlation between input channels and energy balance between the input channels are determined. The determined correlation and energy balance are mapped to output three-dimensional spatial locations.
Claims20
A computer program product having a non-transitory computer-readable medium including computer program logic encoded thereon that, when executed, is configured to convert a plurality of audio input channels with audio that is not explicitly encoded with spatial metadata to object-based audio that includes three-dimensional spatial locations, the computer program product comprising:
- determining a correlation between the audio of the plurality of input channels that is not explicitly encoded with spatial metadata;
- determining energy balance between the audio of the plurality of input channels that is not explicitly encoded with spatial metadata;
- and
- mapping the determined correlation and energy balance to output audio that includes three-dimensional spatial locations.
An audio system that is configured to receive input audio channels with audio that is not explicitly encoded with spatial metadata, comprising:
- multiple loudspeakers spaced about a listening area;
- and
- a processor that is configured to determine a correlation between the audio of the plurality of input channels that is not explicitly encoded with spatial metadata and energy balance between the audio of the plurality of input channels that is not explicitly encoded with spatial metadata, and map the determined correlation and energy balance to output audio that includes three-dimensional spatial locations.
