COMPRESSION OF DECOMPOSED REPRESENTATIONS OF A SOUND FIELD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240276166 titled 'COMPRESSION OF DECOMPOSED REPRESENTATIONS OF A SOUND FIELD
Simplified Explanation: The patent application describes techniques for compressing decomposed representations of a sound field using a device with memory and processing circuitry. The memory stores a bitstream of scene-based audio data, while the processing circuitry extracts foreground components and directional information to reconstruct the audio data.
- **Ambisonic coefficients**: Represent the sound field in the scene-based audio data.
- **Foreground components**: Extracted from the bitstream to focus on key audio elements.
- **Directional information**: Dequantized to obtain accurate spatial details.
- **Reconstructed audio data**: Generated using foreground components and dequantized directional information.
Potential Applications: 1. Virtual reality audio processing. 2. Immersive audio experiences in gaming. 3. Audio production and editing tools.
Problems Solved: 1. Efficient compression of complex sound field data. 2. Accurate reconstruction of audio scenes. 3. Enhanced spatial audio representation.

Original Abstract Submitted
in general, techniques are described for compressing decomposed representations of a sound field. a device comprising a memory and processing circuitry may be configured to perform the techniques. the memory may be configured to store a bitstream representative of scene-based audio data, the scene-based audio data comprising ambisonic coefficients representative of a soundfield. the processing circuitry may be configured to process the bitstream to extract foreground components and corresponding foreground directional information, dequantize the corresponding foreground directional information to obtain corresponding dequantized directional information, and obtain, based on the foreground components and the corresponding dequantized foreground directional information, a reconstructed version of the scene-based audio data.
