Terminal Acoustic Image Localization Without Platform Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio signal processing systems for online conferences rely on a distribution platform for acoustic image localization, which is not feasible without a structure for localization control on the platform side.
Innovation Solution
An audio signal processing method where terminals independently obtain and apply localization control information to perform acoustic image localization processing, allowing for appropriate localization without relying on a distribution platform, using techniques like panning and HRTF-based binaural processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a distribution platform performs acoustic image localization control, then localization accuracy is improved, but system complexity and dependency on platform infrastructure increase
Solution Approach 1:
Each terminal device independently performs acoustic image localization processing on its own audio signals without requiring centralized control from the distribution platform. The terminal obtains localization control information (such as panning parameters or HRTF data) and applies it locally to achieve accurate acoustic image positioning, making the system independent of platform-side localization infrastructure.
Solution Approach 2:
The centralized localization control function is divided and distributed to individual terminal devices. Instead of one platform controlling all localization, each terminal independently handles its own localization processing, breaking down the complex centralized system into multiple simple independent units.
2Reliability
If a distribution platform performs acoustic image localization control, then localization processing capability is improved, but compatibility with platforms lacking localization control structures decreases
Solution Approach 1:
The terminal device independently performs acoustic image localization processing on its own audio signals without requiring centralized control from the distribution platform. The terminal obtains localization control information (such as panning parameters or HRTF data) and applies it locally to achieve accurate acoustic image positioning, making the system independent of platform-side localization infrastructure.
Solution Approach 2:
The localization processing capability is built into each terminal device, making it universally applicable across different distribution platforms regardless of whether they have localization control structures. The same terminal localization mechanism works with any platform that transmits audio signals.

AI summary
An audio signal processing method includes obtaining, performing, and outputting. The step of obtaining includes obtaining localization control information that determines an acoustic image localization position of an own terminal in an audio signal processing system. The step of performing includes performing localization processing on the audio signal of the own terminal, based on the obtained localization control information. The step of outputting includes outputting the audio signal on which the localization processing has been performed.
