ACOUSTIC ENVIRONMENT SIMULATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240038248 titled 'ACOUSTIC ENVIRONMENT SIMULATION
Simplified Explanation
The abstract of this patent application describes a method for encoding and decoding an audio signal with multiple audio components, each associated with a spatial location. The encoding process involves converting the audio components into a first audio signal presentation, along with a set of transform parameters and signal level data. This encoded information is then transmitted to the decoder.
The decoder uses the received transform parameters to reconstruct a simulation input signal intended for an acoustic environment simulation. It also applies a signal level modification to the reconstructed simulation input signal based on the signal level data and data related to the acoustic environment simulation. The attenuated reconstructed simulation input signal is then processed in an acoustic environment simulator.
Bullet points explaining the patent/innovation:
- Encoding and decoding method for an audio signal with multiple audio components.
- Each audio component is associated with a spatial location.
- The encoder converts the audio components into a first audio signal presentation.
- The encoder also generates a set of transform parameters and signal level data.
- The encoded information is transmitted to the decoder.
- The decoder reconstructs a simulation input signal using the transform parameters.
- The decoder applies a signal level modification based on the signal level data and data related to the acoustic environment simulation.
- The attenuated reconstructed simulation input signal is processed in an acoustic environment simulator.
Potential applications of this technology:
- Virtual reality and augmented reality audio systems.
- Surround sound systems.
- Gaming and immersive audio experiences.
- Audio production and post-production.
Problems solved by this technology:
- Reduces the processing load on the decoder by eliminating the need to determine the signal level of the simulation input signal.
Benefits of this technology:
- Improved audio quality and spatial accuracy.
- Enhanced immersive audio experiences.
- Reduced processing load and computational requirements.
Original Abstract Submitted
encoding/decoding an audio signal having one or more audio components, wherein each audio component is associated with a spatial location. a first audio signal presentation (z) of the audio components, a first set of transform parameters (w(f)), and signal level data (�) are encoded and transmitted to the decoder. the decoder uses the first set of transform parameters (w(f)) to form a reconstructed simulation input signal intended for an acoustic environment simulation, and applies a signal level modification (�) to the reconstructed simulation input signal. the signal level modification is based on the signal level data (�) and data (p) related to the acoustic environment simulation. the attenuated reconstructed simulation input signal is then processed in an acoustic environment simulator. with this process, the decoder does not need to determine the signal level of the simulation input signal, thereby reducing processing load.
