Audio Stream Generation via Dynamic Segment Scheduling and Cross-Fading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio systems for relaxation and meditation rely on repetitive sound patterns, which become familiar and disrupt the relaxing or meditative experience, as listeners can predict the order of nature sounds after repeated playback.
Innovation Solution
An audio system generates an infinite stream of non-repeating sounds by rearranging and cross-fading audio segments of varying lengths from finite source clips, using a transfer function to dynamically select and schedule segments, creating a seamless and unpredictable audio experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio recordings are played repeatedly for relaxation and meditation, then the listener becomes familiar with the sound patterns, but this predictability disrupts the relaxing or meditative experience
Solution Approach 1:
The audio system dynamically generates sound sequences by randomly selecting and arranging audio clips from a library, ensuring that each playback session produces a unique sequence of sounds. This dynamic generation process prevents predictability while maintaining consistent audio quality and playback reliability.
Solution Approach 2:
The system uses cross-fading transitions between audio clips to create seamless periodic transitions. Each clip is faded out while the next clip fades in, creating a continuous periodic flow of sound that maintains auditory consistency without repeating identical patterns.
2Adaptability or versatility
If unique non-repeating sound streams are generated from finite source clips, then predictability is reduced, but the segments must be dynamically selected and arranged in real-time
Solution Approach 1:
The audio system automatically selects, arranges, and cross-fades audio clips without requiring manual intervention. The random selection algorithm and automated sequencing system handle the complexity internally, providing unique sound patterns while keeping the user interface simple and requiring no complex configuration.
3Stability of the object's composition
If audio clips are cross-faded to create seamless playback, then the overall sound becomes more continuous, but the transition between segments requires additional processing
Solution Approach 1:
The cross-fading process ensures continuous audio playback by overlapping the end of one clip with the beginning of the next. This continuous transition process eliminates gaps and maintains uninterrupted sound flow, creating seamless playback experience.

AI summary
A method of mixing audio segments from audio clips to generate a unique stream of non-repeating sound, by: (a) inputting a plurality of audio source clips into an audio system; (b) applying a transfer function system to the plurality of audio source clips to select audio segments of the plurality of audio source clips, or applying a scheduling function system to the plurality of audio source clips to select playback times for the plurality of audio source clips; (c) applying a timeline renderer system to arrange the order of the selected audio segments; (d) applying a track renderer system to generate a plurality of audio playback clip tracks; (e) cross-fading the selected audio segments, thereby generating an audio playback clip having a unique sound stream; and (f) playing the audio playback clip having the unique sound stream.
