Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for splicing audio files in multimedia editing are cumbersome, often requiring repetitive recording or the use of professional audio processing software that can be resource-intensive and incompatible with mobile devices, leading to poor user experience and inefficiency.

Innovation Solution

An intelligent terminal determines a target insertion location in a source multimedia file, obtains an audio clip, and inserts a playback switching point into the source audio file based on the clip's playback duration, allowing seamless splicing and playback switching between the source audio file and the audio clip without modifying the original audio file.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If professional audio processing software is used for splicing audio files, then splicing functionality is achieved, but device resource consumption increases and compatibility with mobile devices decreases

Engineering Contradiction:

Improvesplicing functionalityVSAvoidsoftware resource consumption

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a copy of the audio file and performs splicing operations on the copied version rather than the original. This allows the splicing functionality to be implemented without modifying the source audio data permanently, reducing the need for complex professional audio processing software while maintaining mobile device compatibility.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent divides the audio file into segments (first audio file and second audio file) and splices them together through separate processing steps. This segmentation approach simplifies the splicing operation by breaking down the complex task of audio file manipulation into manageable segments that can be processed using lighter-weight software suitable for mobile devices.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If repetitive recording is performed to achieve audio splicing, then audio content can be replaced, but user experience deteriorates and time consumption increases

Engineering Contradiction:

Improveaudio content replacementVSAvoidrecording time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent performs preliminary actions by obtaining and preparing the second audio file before splicing it with the first audio file. This allows the audio content replacement to be done in a single operation rather than requiring repetitive recording sessions, significantly reducing time consumption and improving user experience.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system automatically handles the splicing process by determining the target insertion location and performing the audio file combination without requiring the user to manually perform repetitive recording operations. This self-service approach eliminates the need for users to engage in time-consuming repetitive recording to achieve audio splicing.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If the source audio file is modified directly for splicing, then splicing is achieved, but the original audio file is lost and cancellation becomes difficult

Engineering Contradiction:

Improvesplicing operationVSAvoidoriginal file preservation

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent creates and processes a copy of the audio file rather than modifying the original source audio file directly. This copying approach allows the splicing operation to be performed on a duplicate version, preserving the original file intact and enabling easy cancellation or reversal of the splicing operation if needed.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent prepares the audio file for splicing by creating a working copy in advance, which serves as a cushion or buffer between the original file and the splicing operation. This beforehand preparation ensures that the original audio file remains protected and can be restored if the splicing operation needs to be cancelled or reversed.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

The present disclosure provides a method for splicing an audio file and a computer device. The method includes: an intelligent terminal determines a target insertion location in response to an insertion operation, obtains an audio clip corresponding to the insertion operation, and then determines a playback duration corresponding to the audio clip, furthermore, based on the target insertion location and the playback duration, inserts a playback switching point to a source audio file corresponding to the source multimedia file, where the playback switching point is configured to switch playback between the source audio file and the audio clip during playing the source multimedia file.
