Audio Equalization Orchestrator for Heterogeneous Collaboration Platforms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In heterogeneous computing platforms, ensuring equal audio levels during collaboration sessions is challenging due to variations in device hardware and software configurations, leading to inconsistent audio experiences.
Innovation Solution
The system employs a heterogeneous computing platform with a memory containing firmware instructions that enable devices to provide firmware services. An orchestrator device selects an audio equalization setting based on policies received from ITDMs or OEMs, applying speaker separation models to audio streams without host OS involvement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio streams from multiple participants are combined without equalization, then the collaboration session can proceed with minimal processing, but the audio levels become inconsistent and some participants are harder to hear
Solution Approach 1:
The system dynamically adjusts audio parameters (volume levels, frequency responses) of individual participant streams to achieve consistent overall audio output. The orchestrator modifies gain parameters and applies equalization curves to normalize audio levels across heterogeneous devices.
Solution Approach 2:
The orchestrator acts as an intermediary component that receives audio streams from multiple participants, processes them through equalization algorithms, and outputs normalized combined streams. This mediator handles the complexity of audio balancing centrally rather than requiring coordination between all participant devices.
2Reliability
If speaker separation models are applied to all audio streams, then audio quality is improved, but processing time and computational resources increase
Solution Approach 1:
The system applies speaker separation models selectively rather than uniformly to all audio streams. The orchestrator identifies streams that benefit most from separation processing and applies the model only to those, leaving other streams processed with lighter algorithms to minimize overall processing time.
Solution Approach 2:
The audio processing pipeline is segmented into multiple stages: initial stream separation, selective application of speaker separation models to specific streams, and final combination. This segmentation allows computationally intensive operations to be applied only where necessary rather than to the entire audio mix.
3Adaptability or versatility
If firmware services are used to manage audio equalization, then audio consistency is achieved across heterogeneous devices, but the system requires additional firmware layers and complexity
Solution Approach 1:
The orchestrator firmware service provides universal audio equalization functionality that works across diverse device types and configurations. Rather than requiring device-specific audio processing implementations, the orchestrator implements a unified firmware service that adapts to handle audio streams from any participant device type.
Solution Approach 2:
The orchestrator firmware service acts as an intermediary layer between the heterogeneous audio devices and the collaboration application. It abstracts away device-specific variations and provides consistent audio equalization functionality, allowing the application to work with any device without needing to understand underlying hardware differences.
