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 music due to attenuation of sound frequencies and amplitudes, and there is no effective way to replicate the experience of being in the best seat for those who missed the event.
Innovation Solution
A six-dimensional audio dataset (6DAD) is created using a combination of recorded sound data and virtual sound generation, allowing for the simulation of sound at different locations and distances, which can be played back on a headset with head-tracking technology to enhance the listening experience by recreating the sound environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sound is recorded and played back for distant attendees, then the basic audio information is preserved, but the quality and richness of sound is degraded due to attenuation of frequencies and amplitudes
Solution Approach 1:
The patent creates virtual copies of sound sources at different spatial locations using a six-dimensional audio dataset that captures sound from multiple perspectives (x, y, z coordinates plus time and frequency dimensions). These virtual copies allow distant listeners to experience sound as if they were at optimal listening positions, effectively copying the acoustic environment rather than merely transmitting degraded audio signals.
Solution Approach 2:
The system dynamically adjusts audio parameters including frequency response, amplitude levels, and spatial positioning based on the listener's location and the virtual sound source positions. By changing these parameters in real-time, the system compensates for attenuation effects and recreates the intended acoustic experience regardless of physical distance from the actual sound sources.
2Object-affected harmful factors
If a six-dimensional audio dataset is created to simulate best-seat sound quality, then sound quality and richness are improved, but the device complexity increases
Solution Approach 1:
The patent extends traditional three-dimensional spatial audio to six dimensions by adding time and frequency as explicit dimensions. This 6D audio dataset structure (x, y, z, t, f1, f2) enables comprehensive modeling of sound propagation characteristics, allowing the system to simulate how sound evolves over time and across different frequencies from various spatial positions, thereby achieving superior sound quality reconstruction.
Solution Approach 2:
The audio processing system divides the sound field into multiple discrete virtual sound sources, each represented in the six-dimensional space. By segmenting the complex acoustic environment into manageable components, the system can process and reconstruct each element independently, then combine them to create the overall spatial audio experience, making the complex processing task more tractable.
3Adaptability or versatility
If head-tracking technology is implemented to enhance listening experience, then adaptability to user position is improved, but the device complexity and computational requirements increase
Solution Approach 1:
The head-tracking system continuously monitors the user's head position and orientation, feeding this information back to the audio processing engine. Based on this feedback, the system dynamically adjusts the spatial positioning of virtual sound sources relative to the user's current orientation, ensuring that the auditory experience remains consistent and immersive regardless of head movements, thereby improving adaptability.
