Live Surround Audio Manipulation via Signal Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio equipment and software limitations restrict DJs from manipulating surround audio files, which have more than two audio tracks, preventing them from enhancing audience experience in live performances.
Innovation Solution
A method and device for live manipulation of signal flows via a controller, involving the separation of signal flow layers into sub-signal flows based on a predetermined ratio, allowing for the processing and merging of these sub-signal flows to create a modified series that can be played and manipulated, enabling the playback and manipulation of surround audio with existing hardware and software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If surround audio files with more than two audio tracks are used, then audio spatiality and audience experience are improved, but compatibility with existing audio equipment and software is lost
Solution Approach 1:
The patent divides the surround audio signal into multiple sub-signal flows, each containing a subset of audio tracks. This segmentation allows the system to process complex surround audio (5.1, 7.1 channels) by breaking it down into manageable portions that can be handled by existing stereo equipment, thereby maintaining compatibility while preserving spatial audio experience
Solution Approach 2:
The invention introduces a new dimension of signal processing by organizing audio channels into hierarchical layers. By arranging audio tracks in multiple dimensions (sub-signal flows with varying numbers of channels), the system can represent surround sound spatiality without requiring traditional multi-channel audio equipment, thus resolving the compatibility issue
2Device complexity
If stereo audio manipulation is used, then equipment simplicity is maintained, but audio spatiality and immersion are limited
Solution Approach 1:
The patent segments the audio signal into multiple sub-signal flows that can be independently manipulated. This allows a DJ to maintain simple stereo equipment while achieving complex spatial audio effects by processing separate channel groups through the existing hardware, effectively multiplying the capability without adding equipment complexity
Solution Approach 2:
The invention makes the audio processing system universal by enabling it to handle both stereo and surround audio formats through the same hardware. The controller and processing unit can work with any audio configuration by organizing channels into appropriate sub-signal flows, thus providing multi-functionality without requiring specialized equipment for different audio types
3Productivity
If live manipulation of surround audio is implemented, then audience engagement is enhanced, but hardware and software limitations prevent implementation
Solution Approach 1:
The patent enables live manipulation of surround audio by segmenting the signal into sub-signal flows that can be processed in real-time by existing hardware. The controller can read desired ratios and manipulate individual sub-signal flows independently, allowing dynamic live performance with surround audio without requiring complex hardware upgrades
Solution Approach 2:
The invention performs preliminary organization of audio channels into sub-signal flows before manipulation occurs. By pre-arranging the audio signal structure according to a predetermined ratio, the system prepares the signal for efficient real-time processing, enabling live manipulation while avoiding the need for complex hardware during the actual performance

AI summary
A method for live manipulation of signal flows via a controller. The method includes feeding in a first signal flow and a further signal flow, each having X signal flow layers, where X is greater than 2. The method further includes separating the signal flow layers from each signal flow into a respective series of sub-signal flows, related to the signal flow, as according to a predetermined ratio, where each sub-signal flow has Y sub-signal flow layers, and where Y is smaller than X. The method includes reading a desired ratio between the first signal flow and the further signal flow via a controller. The method includes merging corresponding sub-signal flows as according to the desired ratio in order to obtain a modified series of sub-signal flows. The method includes feeding out the modified series.
