Six-Dimensional Audio Dataset for Concert Sound Replication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Concert attendees seated far from the orchestra experience a lesser quality and richness of sound due to attenuation of frequencies and amplitudes, and there is no effective way to replicate the sound experience of being in the best seat for those who missed the concert.
Innovation Solution
A six-dimensional audio dataset (6DAD) is created using a combination of tangible and virtual microphone arrays, which record and simulate sound sources with spatial coordinates, allowing for the recreation of the sound experience at different locations and times, and can be enhanced by head tracking and attenuation modeling to provide a personalized and immersive audio experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sound is recorded and reproduced for distant attendees, then accessibility is improved, but sound quality and richness deteriorate due to frequency and amplitude attenuation
Solution Approach 1:
The patent transitions from traditional 3D spatial audio to 6D audio by adding frequency and amplitude dimensions. This allows the system to capture and reproduce not just the spatial position of sound sources, but also their spectral characteristics and intensity variations, thereby preserving sound quality while providing accessibility to distant attendees.
Solution Approach 2:
The system captures and reproduces multiple parameters of sound including spatial coordinates (x, y, z), frequency spectrum, and amplitude variations. By maintaining and reproducing these multiple parameters simultaneously, the system preserves the richness and quality of the original sound experience even for attendees who cannot be physically present at the optimal location.
2Manufacturing precision
If 6D audio dataset is created with multiple microphone arrays, then sound quality is improved, but device complexity increases
Solution Approach 1:
The audio capture system is divided into multiple independent microphone arrays positioned at different locations and orientations. Each array captures a specific portion of the acoustic environment, and the system processes and combines these segmented recordings to reconstruct the complete 6D audio dataset, thereby improving sound quality while managing system complexity through modular design.
Solution Approach 2:
The patent creates a universal 6D audio dataset that can be reproduced across multiple platforms and devices. The standardized format allows the same audio dataset to be used for different reproduction scenarios (headphones, speakers, virtual reality systems), reducing the need for device-specific recordings and simplifying the overall system architecture.
3Reliability
If frequency and amplitude attenuation is modeled accurately, then realism is improved, but computational requirements increase
Solution Approach 1:
The system pre-calculates and stores frequency and amplitude attenuation characteristics for different spatial positions and environmental conditions during the audio capture phase. This preliminary modeling allows the reproduction system to simply retrieve and apply pre-computed attenuation data rather than performing complex real-time calculations, thereby achieving realistic sound reproduction while minimizing computational energy requirements during playback.

Function Achieved in This Case
This solution enables attendees to enjoy a high-quality sound experience similar to being in the best seat, regardless of their actual location, and allows for the simulation of missed concerts by recreating the original sound environment with accurate frequency and amplitude attenuation, enhancing the auditory experience.
Implementation Method 1
record and simulate sound sources with spatial coordinates, allowing for the recreation of the sound experience at different locations and times
Implementation Method 2

AI summary
This patent includes a method to generate a six dimensional audio dataset. When listening to the six dimensional audio dataset with an advanced headset disclosed in this patent, a user will enable a user to have precision sound localization and maximize the listening experience. For example, when the audio file is registered to a living room, a user would be able to sit in the “middle of the band” and if desired, reposition the instruments to different locations within the living room to change the audio experience.
