Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital audio processing methods face inefficiencies in generating and processing audio envelopes, which affects the real-time performance of audio output due to repeated processing and function jumps for each audio sampling point.
Innovation Solution
A method and apparatus for audio processing that involve obtaining trigger information for a target time period, determining the target state of an envelope based on this information, identifying a set of audio sampling points corresponding to this state, and rendering these points in batches based on the target state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If audio sampling points are processed individually with repeated function calls, then processing accuracy is maintained, but processing efficiency deteriorates
Solution Approach 1:
The patent merges multiple individual audio sampling point processing operations into a single batch processing operation. By grouping sampling points that share the same envelope state together, the system processes them simultaneously using a single function call, thereby eliminating repeated function calls and improving processing efficiency without sacrificing accuracy
Solution Approach 2:
The patent segments the audio sampling points into different groups based on their envelope states. By dividing the processing task into segments (different envelope states), each segment can be processed efficiently with appropriate optimizations, reducing overall processing complexity while maintaining the accuracy needed for each specific state
2Speed
If envelope processing is performed for each audio sampling point, then real-time performance is compromised, but processing completeness is ensured
Solution Approach 1:
The patent performs preliminary actions by pre-calculating and caching envelope data for multiple sampling points before they are needed for audio output. By preparing the envelope information in advance and storing it for quick retrieval, the system reduces processing time during real-time audio generation, ensuring both speed and completeness
Solution Approach 2:
The patent maintains continuity of useful action by keeping envelope processing operations continuous and uninterrupted. Instead of repeatedly starting and stopping processing for each sampling point, the system maintains a continuous processing stream where envelope data is generated and updated continuously, improving real-time performance while ensuring all necessary processing is completed
