A system utilizing processors and memory to generate a customized audio experience by processing audio samples of a vehicle's interior and audio equipment, creating convolution reverbs, and modifying user audio samples to simulate the vehicle's sound system, allowing for visual comparison and quality scoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If customers want to experience audio quality before purchasing, then audio quality comparison capability is improved, but system complexity increases as no such system currently exists
Solution Approach 1:
The patent creates a virtual copy of the physical audio environment by capturing impulse responses from the vehicle interior and audio equipment, then using convolution reverb to reproduce these acoustic characteristics digitally. This allows customers to experience audio quality online without physically visiting the vehicle, resolving the contradiction by providing measurement capability through virtual replication rather than physical testing infrastructure.
Solution Approach 2:
The system introduces an intermediary processing layer that captures real audio samples, processes them through convolution reverb algorithms, and delivers processed audio experiences to users. This intermediary system bridges the gap between the physical audio environment and the digital comparison interface, enabling audio quality comparison without requiring direct physical access to multiple vehicles.
2Loss of information
If the system processes multiple audio samples to create customized experiences, then audio quality differentiation is improved, but processing time increases
Solution Approach 1:
The system performs preliminary processing by capturing and storing impulse responses from vehicle interiors and audio equipment in advance. These pre-processed acoustic signatures are then reused through convolution reverb when generating customized audio experiences, eliminating the need to re-process raw audio samples for each user interaction and significantly reducing processing time while maintaining audio quality differentiation.
3Measurement precision
If the system provides detailed audio comparison capabilities, then customer decision-making is improved, but ease of operation decreases due to technical complexity
Solution Approach 1:
The patent creates simplified virtual representations of complex audio environments that can be easily manipulated and compared through user interfaces. By copying essential acoustic characteristics into processable digital formats, the system enables customers to compare audio qualities through simple interactions without needing to understand the underlying acoustic measurement and processing complexity.
