Microphone Visual Interface for Real-Time Audio Source Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio recording technologies in portable devices lack the ability to effectively assist users in identifying and improving audio quality, especially in noisy environments or when the sound source is distant, due to the lack of visual feedback and control over microphone settings.
Innovation Solution
A method and apparatus that determine audio sources, generate visual representations of these sources, and process audio signals based on user interaction with these representations, allowing for selection, filtering, and amplification of audio signals from internal or external microphones, including those wirelessly coupled to the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual feedback and control over microphone settings are added, then audio quality improvement capability is enhanced, but device complexity increases
Solution Approach 1:
The patent implements visual feedback mechanisms that display real-time audio quality information to users, including audio level indicators, noise level indicators, and source direction indicators. This feedback enables users to assess and improve audio quality by adjusting microphone settings based on visual information, directly resolving the contradiction by adding measurement precision through feedback displays without requiring complex automated control systems
Solution Approach 2:
The patent introduces visual displays and indicators as intermediary elements between the audio processing system and the user. These intermediaries translate complex audio parameters into comprehensible visual representations, allowing users to control audio quality without needing technical expertise. The visual interface acts as a mediator that simplifies the interaction while providing precise audio quality information
2Reliability
If multiple microphones are used to capture audio from distant sources, then audio capture capability is improved, but device complexity increases
Solution Approach 1:
The patent divides the audio capture function across multiple independent microphones, each capable of capturing audio from different directions and distances. The system processes signals from multiple microphones separately and combines them to improve audio capture from distant sources. This segmentation allows the system to enhance reliability through distributed sensing while keeping individual microphone units simple and manageable
Solution Approach 2:
The patent implements a microphone system where multiple microphones serve universal functions - each microphone can capture audio from any direction and can be individually selected or combined based on recording needs. The system provides multi-functionality by enabling users to switch between single and multiple microphone modes, and to adjust which microphones are active based on the recording situation, thereby improving audio capture capability without requiring dedicated specialized hardware for each function
3Adaptability or versatility
If external microphones are integrated with the device, then audio recording flexibility is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements automatic microphone selection and configuration features that allow the system to self-adjust based on detected audio sources and recording conditions. The system automatically identifies optimal microphone combinations and configures audio processing parameters without requiring manual user intervention. This self-service capability provides extensive audio recording flexibility through multiple microphone options while maintaining ease of operation through automated control
Solution Approach 2:
The patent creates a dynamic microphone system where the active microphone configuration can change in real-time based on user interaction and detected conditions. Users can dynamically switch between different microphone modes (single, dual, stereo) and the system adapts its processing accordingly. This dynamic approach allows the system to provide versatile audio recording capabilities while keeping operation simple through context-aware automatic adjustments and intuitive user controls
4Loss of information
If visual representation of audio sources is provided, then user awareness of audio quality is improved, but device complexity increases
Solution Approach 1:
The patent replaces direct acoustic measurement with visual representation systems that display audio source information graphically. Instead of requiring users to interpret complex audio signals directly, the system substitutes mechanical/acoustic information with visual displays showing source direction, distance, and characteristics. This substitution provides comprehensive audio source information visibility while keeping processing relatively simple by using standard visual display technologies to represent audio data
Data Source
AI summary
An apparatus or method to give a user information about, and control of, internal and/or external microphone(s) so that the user can make adjustments to audio recording in real time. The method includes choosing microphones, displaying visual representations of microphones, capturing an acoustic source using a microphone, allowing a user to interact with a visual representation of a microphone to select or deselect the microphone, and processing of the audio signal from the acoustic source captured by a microphone.
