Wide Effect Sound Production via Variable Delay Signal Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound reproduction systems, such as stereophonic and car stereo systems, fail to produce a wide effect sound by combining signals from left and right speakers effectively, especially beyond a 50-millisecond delay range, and are costly, limiting consumer experience.
Innovation Solution
A method for producing a wide effect sound by creating a lead and lag music composition with variable delays between 51 and 3000 milliseconds, where the lead and lag signals can be dynamically altered in decibel levels, allowing for a wide sound effect composition that can be recorded on a medium for playback on various electroacoustic devices without requiring expensive stereophonic sound reproduction systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If delay replication is extended beyond 50 milliseconds to achieve wider sound effects, then the wide effect sound quality is improved, but existing systems cannot support delays higher than 50 milliseconds
Solution Approach 1:
The system dynamically adjusts delay times between left and right channel signals, allowing variable delay ranges from 0 to several seconds. This dynamic control enables the system to adapt to different wide effect requirements while maintaining signal integrity and combining left-right signals effectively.
Solution Approach 2:
The system changes the delay parameter from fixed (0-50ms in car stereos) to variable (0 to several seconds), and adjusts signal combination parameters to merge left and right channels with delayed signals. This parameter transformation enables extended delay ranges while maintaining system reliability.
2Adaptability or versatility
If expensive stereophonic sound reproduction systems are used to achieve dimensionalized sound effects, then the sound quality is improved, but the cost increases and limits consumer experience
Solution Approach 1:
The system provides wide effect sound capabilities that were previously only available in expensive stereophonic systems, making this functionality universal and accessible to consumers with standard equipment. The method works with any two-channel audio system, not requiring specialized hardware.
Solution Approach 2:
The system creates a delayed copy of the audio signal and combines it with the original signal. This copying approach reproduces the dimensionalized sound effect of expensive systems using simple delay and signal combination techniques, eliminating the need for costly equipment.
3Device complexity
If signals from left and right speakers are kept isolated and separate, then the system simplicity is maintained, but the full composition signals are not combined and wide effect is not achieved
Solution Approach 1:
The system merges left and right channel signals by combining the original signal with a delayed version of the signal. This combination process integrates separate left-right signals to create a unified wide effect output, achieving full composition signal integration while maintaining processing simplicity.
