AUDIO CHANNEL SPATIAL TRANSLATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18474170 titled 'AUDIO CHANNEL SPATIAL TRANSLATION
Simplified Explanation
The present invention is directed to methods and apparatus for translating a first plurality of audio input channels to a second plurality of audio output channels. This includes determining pair-wise coding among the input channels, mapping the input channels to the output channels using a matrix, and deriving the output channels based on the input channels and coding.
- Determining pair-wise coding among the audio input channels
- Mapping the input channels to the output channels using a matrix
- Deriving the output channels based on the input channels and coding
Potential Applications
This technology could be applied in:
- Surround sound systems
- Virtual reality audio
- Audio production and mixing
Problems Solved
This technology solves the problem of efficiently translating multiple audio input channels to a different set of output channels while maintaining the original sound field representation.
Benefits
- Improved audio quality
- Enhanced spatial audio experience
- Simplified audio channel mapping process
Potential Commercial Applications
- Audio equipment manufacturing
- Entertainment industry (film, gaming)
- Virtual reality technology development
Possible Prior Art
One possible prior art for this technology could be the use of matrix decoding in surround sound systems to map audio channels to different speakers.

Original Abstract Submitted
The present invention is directed to methods and apparatus for translating a first plurality of audio input channels to a second plurality of audio output channels. This includes determining that there is pair-wise coding among any of the first plurality of audio input channels, determining an input/output-mapping matrix for mapping at least a first set of the first plurality of audio input channels to at least a second set of the second plurality of audio output channels; and deriving the second plurality of audio output channels based on first plurality of audio input channels, the input/output-mapping matrix and the determined pair-wise coding. The first plurality of audio input channels represent the same soundfield represented by the second plurality of audio output channels.
