Pseudo Crowd Audio Control for Low-Bitrate Live Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing live distribution systems lack the ability to provide realistic and individualized audio feedback to performers, requiring high bit rates that can cause transmission issues and relying on uniform sound effects that lack ambiance.
Innovation Solution
An information processing apparatus and method that generates and outputs individual pseudo sound data reflecting the unique characteristics of participant reactions, using a control unit to select and output pseudo sound data from an audio output apparatus in the venue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-quality participant reaction sounds are delivered to the performer in real time, then the feedback realism and ambiance are improved, but the bit rate requirement increases causing transmission problems
Solution Approach 1:
The system creates pseudo sound data that copies and simulates the characteristics of actual participant reaction sounds without transmitting the original high-bitrate audio. Template sound data is processed to generate pseudo sounds that reflect participant reactions, enabling quality feedback at lower bit rates
Solution Approach 2:
The system transforms the parameter representation of sound data by using synthesized pseudo sound data with modified parameters derived from template sounds and participant reaction information, rather than transmitting original audio parameters directly
2Reliability
If prepared sound effect materials are used for participant reactions, then transmission problems are avoided, but the sounds become uniform and lack ambiance
Solution Approach 1:
The system applies individualized characteristics to each participant's reaction sound by processing template sounds with participant-specific parameters, creating locally adapted pseudo sound data that maintains both transmission reliability and individual sound identity
Solution Approach 2:
The system dynamically generates pseudo sound data based on actual participant reactions rather than using static prepared sounds. The pseudo sound data changes according to participant behavior, maintaining versatility while ensuring transmission stability
Data Source
AI summary
Provided is an information processing apparatus including a control unit that performs control for selecting individual pseudo sound data corresponding to acquired reaction information indicating a reaction of a participant from one or more pieces of individual pseudo sound data reflecting a feature of a sound uttered by the participant. Further, the control unit outputs the selected individual pseudo sound data from an audio output apparatus installed in a venue.
