Audio Stream Editing via Pause Segment Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio editing tools are complex and time-consuming, requiring users to re-record entire audio files to edit specific sections, making them inefficient for updating narrated content or removing unwanted noises.
Innovation Solution
A system and method that records audio streams with pause segments, allowing users to identify and replace specific audio segments by processing the audio stream to determine silence periods, enabling efficient editing of audio segments without redoing the entire recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional audio editing tools are used to edit specific sections of recorded audio, then the audio can be corrected or updated, but the entire audio must be re-recorded which is tedious and time-consuming
Solution Approach 1:
The audio stream is divided into discrete audio segments separated by pause segments. This segmentation allows the system to identify and edit individual segments independently, rather than requiring re-recording of the entire audio stream. The processor detects pause segments (periods of silence) to automatically delimit audio segments, enabling precise editing of specific portions while preserving other segments.
Solution Approach 2:
The system extracts the specific audio segment that needs editing by identifying it through pause segments. Once the target segment is extracted/isolated, it can be replaced with a new recording of just that segment, while the rest of the audio stream remains unchanged. This extraction approach eliminates the need to re-record the entire audio.
2Reliability
If audio editing tools are used to correct errors or remove unwanted noises, then the audio quality can be improved, but the complexity of the editing process increases
Solution Approach 1:
The system performs automatic segmentation of audio streams by detecting pause segments (periods of silence) without requiring manual intervention. The processor automatically identifies where audio segments begin and end based on the presence of pause segments, eliminating the need for users to manually navigate through audio editing software to locate specific sections. This self-service approach simplifies the user interface while maintaining high audio quality through precise segment replacement.
3Manufacturing precision
If the entire audio stream is re-recorded to edit a specific section, then editing accuracy is achieved, but productivity decreases
Solution Approach 1:
The audio stream is segmented into discrete units separated by pause segments, allowing precise editing of individual segments. The processor identifies pause segments to automatically delimit segments, ensuring accurate editing boundaries. This segmentation enables replacement of only the problematic segment while preserving the rest of the audio, achieving both editing accuracy and improved productivity.
Solution Approach 2:
Instead of re-recording the entire audio stream (excessive action), the system applies editing action only to the specific segment that contains errors or unwanted content (partial action). The processor identifies the target segment through pause segment detection and replaces only that portion, achieving necessary editing accuracy while significantly improving productivity by avoiding redundant re-recording of unaffected segments.

AI summary
A method for editing an audio stream includes recording and storing an audio stream having a first audio segment and a second audio segment. The method includes receiving a request to edit the second audio segment and processing the audio stream to identify a first pause segment defining a period of silence from an end of the first audio segment to a start of the second audio segment. Further, the method includes determining the second audio segment as a segment beginning at an end of the first pause segment and terminating either at an end of the audio stream or at a beginning of a second pause segment recorded in succession to the second audio segment, obtaining a third audio segment including a revised version of the second audio segment, and replacing the second audio segment with the third audio segment.
