Audio Installation Equalization Parameter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio reproduction systems lack an efficient method to automatically apply different sets of equalization parameters to multiple audio devices playing the same audio stream, requiring user intervention and complex configuration.
Innovation Solution
A device separate from the audio reproduction equipment controls the application of equalization parameters, determining whether multiple devices should apply the same or different settings, and synchronizes the audio stream using timestamp information and reference clocks, allowing automatic parameter application without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user manually configures equalization parameters for each audio playback device, then the equalization settings can be customized per device, but the configuration process becomes complex and time-consuming
Solution Approach 1:
The system automatically determines whether audio playback devices are in the same group and applies appropriate equalization parameters without requiring manual user configuration. The control device autonomously manages the equalization setup process, eliminating the need for users to manually configure each device while still achieving customized equalization settings based on device grouping status.
Solution Approach 2:
The control device pre-determines the grouping status of audio playback devices before audio playback begins. By提前 identifying which devices are in the same group, the system can automatically apply the correct equalization parameters in advance, avoiding complex real-time configuration decisions and simplifying the user experience.
2Reliability
If different equalization parameters are applied to each audio playback device, then the audio quality can be optimized for each device's characteristics, but the system complexity increases
Solution Approach 1:
The system applies different equalization parameters to audio playback devices based on their local characteristics and grouping status. Devices in the same group receive appropriate equalization settings tailored to their specific audio characteristics, while maintaining system-wide coherence. This allows optimized audio quality for each device without requiring complex centralized management of all parameters.
3Ease of operation
If the system automatically determines device grouping and applies equalization parameters, then user intervention is eliminated, but the automation complexity increases
Solution Approach 1:
A control device acts as an intermediary between the audio playback devices and the equalization parameter management system. This intermediary automatically determines device grouping status and applies appropriate equalization parameters, eliminating the need for direct user intervention while centralizing the automation logic in a manageable component rather than distributing complexity across all devices.

AI summary
A method comprising the steps of determining by a device in an installation whether an audio stream is being played in the installation by a single audio playback device or by a group of at least two audio playback devices (11a, 11b); if the device detects that the audio stream is being played by a single audio playback device then the device generates an order to apply a given set of equalization parameters to said device and if the device detects that the audio stream is being played by a group of at least two audio playback devices then the device determines the equalization parameters to be applied by each audio playback device in said group, and generates an order to apply a given set of equalization parameters to each audio playback device in said group.
