HEAD-RELATED TRANSFER FUNCTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240187814 titled 'HEAD-RELATED TRANSFER FUNCTION
Simplified Explanation
The patent application describes systems and methods for efficiently processing an audio track of a virtual object with a head-related transfer function (HRTF).
- Determining the current position of the virtual object with respect to the user's head
- Identifying a current audio zone from predefined audio zones based on the determined position
- Applying left and right predefined filters corresponding to the current audio zone to the audio track
- Producing a left audio signal and a right audio signal
- Presenting the left audio signal with a first speaker and the right audio signal with a second speaker
Potential Applications: - Virtual reality and augmented reality systems - Gaming and entertainment industries - Audio engineering and sound design
Problems Solved: - Providing immersive audio experiences in virtual environments - Enhancing spatial audio perception for users - Optimizing audio processing for virtual objects
Benefits: - Improved realism and immersion in virtual environments - Enhanced user experience in gaming and entertainment - Precise audio localization for better spatial awareness
Commercial Applications: Title: "Enhanced Spatial Audio Processing for Virtual Environments" This technology can be used in virtual reality headsets, gaming consoles, audio software, and entertainment systems to provide users with a more immersive and realistic audio experience.
Prior Art: There may be existing patents related to audio processing in virtual environments, but the specific combination of determining current position, applying predefined filters, and presenting audio signals with speakers may be novel.
Frequently Updated Research: Stay updated on advancements in spatial audio processing, HRTF technology, and virtual reality audio solutions to enhance the efficiency and effectiveness of this system.
Questions about Spatial Audio Processing: Question 1: How does this technology improve spatial audio perception for users? Answer: This technology enhances spatial audio perception by accurately processing audio tracks based on the virtual object's position relative to the user's head, creating a more realistic and immersive audio experience.
Question 2: What are the potential challenges in implementing this technology across different audio devices? Answer: Implementing this technology across various audio devices may require compatibility adjustments and calibration to ensure consistent and accurate spatial audio processing.
Original Abstract Submitted
example systems, devices, media, and methods are described for efficiently processing an audio track of a virtual object with a head-related transfer function (hrtf). audio tracks are processed by determining a current position (direction and optionally distance) of the virtual object with respect to the head of a user, identifying a current audio zone from predefined audio zones responsive to the determined current position where each of the audio zones has a corresponding left predefined filter and a corresponding right predefined filter, applying the left and the right predefined filters corresponding to the current audio zone to the audio track to produce a left audio signal and a right audio signal, and presenting the left audio signal with a first speaker and the right audio signal with a second speaker.
