Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If media data with various loudness are pulled to the same playing loudness through volume gain and forced clipping, then playing loudness balance is achieved, but adaptability to different playing environments and device attributes is lost
Solution Approach 1:
The patent applies dynamics by making the loudness processing parameters adjustable based on different playing environments and device attributes. Instead of using fixed volume gain and clipping, the system dynamically determines processing parameters (such as compression ratio, threshold values) according to the detected playing conditions, allowing the same media data to be processed differently for different scenarios while maintaining loudness balance.
Solution Approach 2:
The patent changes processing parameters based on detected playing environments and device attributes. The system obtains audio features of the media data and combines them with loudness requirement information (including playing environment and device attributes) to determine appropriate loudness processing parameters, such as compression ratios and threshold values, which are then applied to process the media data accordingly.
2Device complexity
If loudness processing is conducted on media data at a playing side without considering playing environment, then processing simplicity is maintained, but playing effect consistency across different environments is compromised
Solution Approach 1:
The patent implements feedback by detecting the actual playing environment and device attributes, then using this information to adjust the loudness processing parameters. The system obtains loudness requirement information that includes playing environment data and device attributes, combines this with audio features of the media data, and uses the combined information to determine processing parameters, ensuring consistent playing effects across different environments.
