Atmosphere Creation System Using Audio Signal Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atmosphere creation systems require manual and complex adjustments to match social settings and moods in environments, which can be time-consuming and require expert knowledge, and do not effectively integrate multiple atmosphere modalities like lighting, sound, images, and smells.
Innovation Solution
A system that automatically creates an atmosphere by analyzing audio signals to determine social settings and moods, using a sound receiving unit, audio signal processing unit, and atmosphere creation unit to generate control signals for lighting, audio, display, smell, and climate control systems, with features like audio content analysis, classification, and look-up tables to adapt to dynamic environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment is used to create atmosphere, then atmosphere can be customized to social setting, but it requires user expertise and time consumption
Solution Approach 1:
The system automatically analyzes audio signals from the environment and self-adjusts atmosphere parameters without requiring user expertise or manual intervention. The audio analysis unit processes ambient sounds to determine social setting, and the atmosphere creation unit automatically adjusts lighting, music, and other parameters to match the detected social context.
Solution Approach 2:
The system continuously monitors the audio environment and uses this feedback to dynamically adjust atmosphere parameters. The audio analysis unit provides real-time information about social setting to the atmosphere creation unit, which then modifies atmosphere parameters accordingly, creating a closed-loop control system.
2Adaptability or versatility
If multiple atmosphere modalities are integrated, then comprehensive atmosphere creation is achieved, but system complexity increases
Solution Approach 1:
The atmosphere creation unit serves multiple functions by controlling different atmosphere modalities including lighting, music playback, and other environmental parameters. A single integrated system handles diverse atmosphere creation tasks based on audio analysis, eliminating the need for separate control systems for each modality.
3Extent of automation
If automatic audio analysis is used, then user interaction is minimized, but accuracy of social setting detection may be compromised
Solution Approach 1:
The system replaces manual user input mechanisms with automated audio signal analysis. Instead of requiring users to manually set atmosphere parameters or provide input signals, the system uses audio analysis to automatically detect social setting and generate appropriate atmosphere responses.

AI summary
The invention relates to the automatic creation of an atmosphere such as a lighting atmosphere combined with music, which is suited to social setting and mood in an environment such as a room. An embodiment of the invention provides a system (10) for automatically creating an atmosphere suited to social setting and mood in an environment (12), comprising - a sound receiving unit (14) being adapted for receiving sound (161, 162, 163) from the environment (12) and generating an audio signal (18) representing the received sound, - an audio signal processing unit (20) being adapted for receiving and analyzing the audio signal (18) for social setting and mood in the environment (12), and - an atmosphere creation unit (22) being adapted for automatically generating control signals (24) for an atmosphere creation system (26) for creating an atmosphere based on the result (28) of the analysis of the audio signal (18). This system allows a comfortable and automatic creation of an atmosphere, which is suited to social setting and mood in an environment, for example in a room.
