Solution Overview

Problem

Large or long-duration audio files require complex and time-consuming decoding processes, leading to memory occupation issues and browser crashes in web front-end applications, which affects performance and timeliness.

Innovation Solution

An audio processing method that determines decoding start and end frame identifications in a preset frame sequence, acquires segment data for decoding, and decodes it to obtain target decoded data, allowing for on-demand decoding without full audio file decoding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If full decoding of audio files is performed, then audio processing completeness is ensured, but memory consumption increases and browser crashes occur

Engineering Contradiction:

Improveaudio processing completenessVSAvoidmemory consumption

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent segments the audio file into multiple audio frames with associated frame identifications. Instead of decoding the entire audio file at once, the system decodes only the specific frames needed for processing. This segmentation approach reduces memory consumption by loading and decoding only necessary portions of the audio data while maintaining processing completeness through systematic frame selection.

Inventive Principle:

Principle #1Segmentation

2Reliability

If full decoding of audio files is performed, then audio processing completeness is ensured, but processing time increases and timeliness is affected

Engineering Contradiction:

Improveaudio processing completenessVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent divides the audio file into discrete frames and uses frame identification mechanisms to track and process only the necessary frames. This segmentation enables selective decoding of specific time segments rather than sequential decoding of the entire file, significantly reducing processing time while maintaining completeness through systematic frame processing.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary actions by pre-establishing frame identification mappings and audio frame metadata before actual decoding occurs. This preliminary preparation includes creating the frame sequence structure and pre-loading audio frame information, which enables rapid selective decoding without requiring full file processing, thus improving timeliness.

Solution Approach 1:

The patent segments the audio file into discrete frames with associated identifications and metadata. This segmentation approach, combined with systematic frame tracking mechanisms, enables efficient selective decoding that reduces processing time while managing implementation complexity through structured organization of audio data and processing logic.
