Solution Overview
Problem
Current electronic devices lack the capability to efficiently identify and render songs being played in the user's environment, failing to provide a seamless listening experience by synchronizing audio information with environmental sound sources.
Innovation Solution
An electronic apparatus that receives microphone audio information, identifies songs, displays song indicators, and renders song audio information based on user inputs, utilizing directional audio analysis and synchronization techniques to mimic the environmental audio experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If song identification and rendering functionality is added to electronic devices, then the listening experience is enhanced, but the device complexity increases
Solution Approach 1:
The electronic device integrates multiple functions including microphone-based audio capture, song identification through audio analysis, visual display of song information, and audio rendering capabilities. This multi-functional integration allows a single device to serve as an environmental song player, eliminating the need for separate dedicated devices and enhancing versatility while managing complexity through consolidation.
2Ease of operation
If audio synchronization with environmental sound sources is implemented, then the seamless listening experience is improved, but the processing requirements and energy consumption increase
Solution Approach 1:
The system performs preliminary song identification by analyzing audio captured from the environment before initiating full audio rendering. By pre-identifying the song through microphone input and matching it against a database, the device prepares the audio content in advance, enabling seamless playback without requiring continuous high-energy processing during the actual listening experience.
Solution Approach 2:
The device autonomously captures environmental audio through its microphone, automatically identifies the song, retrieves the corresponding audio file, and renders it without requiring manual user intervention. This self-service approach minimizes the need for continuous user interaction and optimizes energy usage by activating processing only when environmental audio triggers song identification.
3Measurement precision
If directional audio analysis is used to align audio rendering with sound source direction, then the spatial accuracy is improved, but the computational complexity increases
Solution Approach 1:
The system applies directional audio analysis specifically to determine the spatial direction of the sound source, focusing computational resources on this localized function rather than进行全面 audio processing. By concentrating the complex directional analysis on identifying the sound source direction and using this information specifically for spatial alignment of the rendered audio, the patent achieves improved spatial accuracy while managing computational complexity through targeted application of the technique.
