Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless microphone systems lack an efficient method to associate audio signals with their corresponding sound sources, especially in multi-source scenarios, leading to difficulties in live monitoring and post-processing.
Innovation Solution
A wireless microphone system that includes multiple wireless microphones each generating an audio signal with embedded identification information, and a monitoring device that visualizes these signals with corresponding identification features, allowing for easy association of audio signals with their sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless microphones are used to capture audio from multiple sound sources, then flexibility and mobility are improved, but the ability to quickly associate audio signals with their corresponding sound sources deteriorates
Solution Approach 1:
The system performs preliminary action by automatically generating and displaying visual representations of sound sources and their corresponding audio signals in real-time during the recording session. This allows the audio technician to immediately associate audio signals with sound sources without manual note-taking, resolving the time loss issue while maintaining wireless flexibility
Solution Approach 2:
The system introduces an intermediary visual display that acts as a mediator between the wireless microphones and the audio technician. The display shows visual representations of sound sources and their corresponding audio signals, enabling quick association without physical cables or manual documentation, thus solving the contradiction between wireless operation and signal association
2Device complexity
If wireless microphones are used without manual naming, then setup complexity is reduced, but the ability to identify specific microphones during monitoring deteriorates
Solution Approach 1:
The system applies color changes by displaying visual representations of sound sources with distinct visual characteristics (such as color coding) that correspond to specific wireless microphones. This allows the audio technician to easily identify which microphone is generating which audio signal without manual naming, reducing setup complexity while improving detectability
Solution Approach 2:
The system creates visual copies or representations of the physical sound sources and their corresponding audio signals on the display. These visual representations serve as proxies that make it easy to identify and track specific microphones during monitoring, eliminating the need for manual naming while maintaining identifiability
3Loss of information
If manual notes are taken during recording, then audio signal identification is possible, but the recording process complexity and time consumption increase
Solution Approach 1:
The system implements self-service by automatically generating and maintaining the association between audio signals and sound sources through visual representations on the display. This eliminates the need for the audio technician to manually take notes, preserving complete information about signal sources while significantly improving recording efficiency and productivity
