Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies struggle to accurately determine whether audio is from a direct vocal interaction or thinking aloud, especially in scenarios involving augmented reality, where audio characteristics are distorted due to varying spatial conditions and altered realities.
Innovation Solution
The method involves determining spatial parameters of a first space with sound sources and audio sources, calculating vocal spatial parameters, and generating a clean version of audio data to accurately reflect the original sound characteristics, allowing for precise audio teleportation and preservation across different spaces, including altered reality environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If audio is teleported from one space to another with different spatial characteristics, then communication reach is improved, but audio realism deteriorates due to mismatched spatial parameters
Solution Approach 1:
The system changes audio parameters by applying inverse spatial filtering to remove the characteristics of the source space, then applies the characteristics of the target space to match the spatial parameters. This allows audio to be accurately adapted when teleported between spaces with different acoustic characteristics, maintaining realism while enabling remote communication.
Solution Approach 2:
The system creates a copy of the spatial characteristics of the target space and applies it to the teleported audio. By copying the spatial impulse response of the destination environment and convolving it with the captured audio, the system reproduces the audio as if it were originally recorded in that space, preserving realism across different locations.
2Adaptability or versatility
If spatial parameters are adjusted to match different environments, then audio adaptability is improved, but processing complexity increases
Solution Approach 1:
The system performs preliminary action by pre-calculating and storing spatial impulse responses for different environments. When audio needs to be teleported, the system simply retrieves the appropriate pre-computed spatial characteristics and applies them through convolution, avoiding the need for complex real-time calculations and reducing processing complexity while maintaining adaptability.
3Measurement precision
If vocal spatial parameters are determined for each sound source, then measurement precision is improved, but computational requirements increase
Solution Approach 1:
The system segments the audio processing by determining vocal spatial parameters for each sound source independently. By processing each sound source separately and applying individual spatial filtering, the system achieves high measurement precision for each source while managing computational energy through parallel processing and efficient algorithms.
