SPATIAL AUDIO PARAMETER ENCODING AND ASSOCIATED DECODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240029745 titled 'SPATIAL AUDIO PARAMETER ENCODING AND ASSOCIATED DECODING
Simplified Explanation
The patent application describes an apparatus that obtains audio signals and their corresponding spatial audio signal parameter values in a time-frequency domain. It then determines a merge metric to control the merging of these parameter values over time and frequency. Based on this merge metric, the apparatus merges the spatial audio signal parameter values into a smaller number of values over time and/or frequency.
- The apparatus obtains audio signals and their spatial audio signal parameter values.
- It determines a merge metric to control the merging of these parameter values over time and frequency.
- Based on the merge metric, it merges the parameter values into a smaller number of values over time and/or frequency.
Potential Applications:
- Audio signal processing in virtual reality (VR) or augmented reality (AR) systems.
- Spatial audio rendering in gaming or entertainment applications.
- Enhancing audio quality in teleconferencing or video conferencing systems.
Problems Solved:
- Reducing the complexity and size of spatial audio signal parameter values.
- Improving the efficiency of audio signal processing algorithms.
- Enhancing the immersive experience in VR/AR systems by accurately representing spatial audio.
Benefits:
- Improved audio processing efficiency and reduced computational requirements.
- Enhanced spatial audio experience for users.
- More effective utilization of limited bandwidth in audio transmission.
- Improved audio quality and realism in virtual environments.
Original Abstract Submitted
an apparatus comprising means configured to: obtain at least one audio signal; obtain, for the at least one audio signal, spatial audio signal parameter values, the spatial audio signal parameters values distributed within a time-frequency domain (); determine a merge metric to control a merging of the spatial audio signal parameter values over the time-frequency domain (); and merge (), based on the merge metric (), the spatial audio signal parameter values to a smaller number of spatial audio signal parameter values overtime and/or frequency within the time-frequency domain.
