Microphone Tracking Audio Processing for Positional Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio processing techniques fail to provide adaptive solutions for improving audio quality when microphones are incorrectly positioned, leading to reduced sound quality due to boomy, thin, or quiet sounds.
Innovation Solution
An audio system that includes a chain of discrete subcomponents, each performing specific audio processing functionalities, uses sensors to track the position of microphones and users, enabling dynamic adjustments to corrective equalization, compression, and other audio processing operations based on real-time positional data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed corrective equalization and compression techniques are used, then audio processing is simplified, but audio quality deteriorates when microphones are incorrectly positioned
Solution Approach 1:
The patent implements dynamic audio processing by continuously adjusting equalization and compression parameters based on real-time microphone position detection. The system transitions from fixed processing to adaptive processing that responds to changing spatial conditions, thereby maintaining audio quality consistency across different microphone positions without requiring complex manual reconfiguration
Solution Approach 2:
The system employs feedback mechanisms by detecting microphone position and using this information to automatically adjust audio processing parameters. The detected position data feeds back to the audio processing module, which then applies appropriate equalization and compression settings to compensate for incorrect positioning, resolving the contradiction between simplicity and reliability
2Reliability
If adaptive audio processing based on real-time position tracking is implemented, then audio quality improves, but device complexity increases
Solution Approach 1:
The patent divides the audio processing system into discrete functional modules: position detection module, processing parameter determination module, and audio signal processing module. Each module performs a specific function, making the overall complex system manageable and maintainable while achieving adaptive audio quality improvement through coordinated operation of these segmented components
Solution Approach 2:
The audio processing device is designed to handle multiple functions within a single integrated system: it detects microphone position, determines appropriate processing parameters, and applies audio processing all in one device. This multi-functionality approach achieves adaptive audio quality without requiring separate dedicated systems for each function, thereby limiting the increase in overall device complexity

AI summary
An audio system may include a microphone and an audio receiver that is communicatively coupled to the microphone. The receiver and/or the microphone may perform audio processing on one or more audio signals generated by the microphone. The audio processing may be based on a position of the microphone, a position of a user of the microphone (e.g., position of the user's mouth), and/or a relative position of the microphone and the user. The dynamic position-based audio processing provides for a customized and adaptive audio processing, such as a dynamically adjusted corrective equalization (EQ), compression, and/or advanced audio processing operation(s) that may use a machine learning algorithm. This advantageously improves the audio quality and performance in situations where the microphone is incorrectly positioned.
