Audio Control Signal Mapping for Conflicting Parameter Inputs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In systems with multiple processing modules, there is a need to combine and reconcile potentially conflicting user inputs or control signals to generate a unified set of parameters for achieving desired levels of perceptual attributes in audio signals, as direct mapping between user controls and internal parameters is often not straightforward.
Innovation Solution
A process and system that map external control signals to internal parameters, using interpolation and attribute engines to combine conflicting signals, allowing for the generation of combined parameter values for signal processing modules, thereby achieving desired perceptual attributes in audio signals.

Engineering Contradiction Analysis
1Adaptability or versatility
If multiple distinct processing modules are used to perform different operations in response to external control signals, then the system can achieve multiple perceptual attributes in audio signals, but conflicting control signals may produce contradictory parameter values for the same processing module
Solution Approach 1:
The patent introduces an intermediary mechanism (the control signal mapping system) that receives conflicting control signals from multiple processing modules and reconciles them into consistent internal parameter values. This intermediary layer prevents direct conflict by mediating between the diverse control signals and the processing modules, ensuring parameter consistency while maintaining versatility.
Solution Approach 2:
The system dynamically changes parameters based on control signal mappings, where external control signals are transformed into appropriate internal parameter values through defined mapping relationships. This allows the system to adapt parameters flexibly to achieve different perceptual attributes while maintaining consistency through the mapping framework.
2Ease of operation
If a single external control signal is mapped to multiple internal parameters, then the system can simplify user interface operations, but the mapping relationship becomes complex and non-trivial
Solution Approach 1:
The patent segments the control signal mapping process into distinct components: external control signals are separated into individual mappings for different internal parameters. Each mapping relationship is defined independently, allowing the system to manage complexity by breaking down the overall mapping into manageable segments rather than handling all parameters simultaneously.
Solution Approach 2:
The mapping system serves multiple functions: it translates user-friendly external control signals into various internal parameters, handles conflicts between multiple control signals, and maintains consistency across different processing modules. This multi-functional approach consolidates complexity into a single universal mapping mechanism rather than requiring separate control logic for each parameter.

AI summary
Mapping a plurality of external control signals to values for one or more internal parameters is disclosed. Each external control signal is mapped to a control signal-specific set of internal parameter values corresponding to the level of the signal. The resulting signal-specific sets of internal parameter values are combined to generate a combined set of internal parameter values. The combined set of internal parameter values includes a single value for each internal parameter for which a value was included in at least one signal-specific set of internal parameter values. For each internal parameter for which a value is included in more than one of the signal-specific sets of internal parameter values, the combined set of internal parameter values includes a combined value based at least in part on the values included in the signal-specific sets of internal parameter values.
