Engineering Contradiction Analysis
1Productivity
If dedicated hardware or digital signal processor is used to execute audio processing algorithms, then processing capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces dedicated hardware or digital signal processor with a general-purpose processor executing software instructions. The audio processing functions (automatic gain control, noise gate, smart volume control) are implemented through software algorithms rather than specialized hardware circuits, thereby reducing device complexity and cost while maintaining processing capability.
2Productivity
If dedicated hardware or digital signal processor is used to execute audio processing algorithms, then processing capability is improved, but cost increases
Solution Approach 1:
The patent substitutes specialized hardware with general-purpose processing, reducing manufacturing costs. By implementing audio processing algorithms in software on standard processors, the system eliminates the need for expensive dedicated hardware components, making the device more cost-effective to manufacture.
Solution Approach 2:
The patent employs a general-purpose processor that can handle multiple functions including audio processing, control operations, and data management. This multi-functional approach replaces specialized single-function hardware, reducing overall system cost while maintaining processing capability across various audio processing tasks.
3Measurement precision
If audio signal is processed in real-time with detailed analysis, then processing quality is improved, but processing time increases
Solution Approach 1:
The patent divides the audio signal into frames and further into sub-frames for processing. This segmentation allows the system to analyze audio characteristics in manageable portions, maintaining processing quality through detailed analysis while reducing overall processing time by handling smaller data units sequentially rather than analyzing the entire signal at once.
Solution Approach 2:
The patent applies processing operations selectively to specific portions of the audio signal (partial action) rather than uniformly processing the entire signal. By focusing computational resources on critical segments and using different processing depths for different audio characteristics, the system achieves high processing quality where needed while minimizing unnecessary processing time.

AI summary
An audio processing system and a method thereof are provided. The system includes an audio receiver and an audio processor device. The audio receiver includes an audio interface, an absolute value converter unit, a framing unit and a characteristic value detector unit. The audio interface receives an audio signal from an audio transceiver device. The absolute value converter unit takes an absolute value of the audio signal to output an absolute value audio signal. The framing unit divides the absolute value audio signal into a plurality of sub-frame signals. The characteristic value detector unit detects characteristic values of the sub-frame signals. The audio processer processes the audio signal outputted by the audio transceiver device according to the characteristic values of the sub-frame signals.
