Audio Dynamics Processing with Independent Delay Time Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional compressors have difficulty controlling delay time independently of the Attack parameter, leading to uniform control of audio signal characteristics, which limits the flexibility in dynamics processing.
Innovation Solution
A dynamics processing method that determines whether the audio signal level exceeds a threshold and elapses a specified time before applying gain changes, allowing for independent control of delay time and enabling more flexible control of audio signal changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If delay time is determined by Attack parameter in conventional compressors, then the control structure is simple, but the delay time cannot be controlled independently and is uniquely determined
Solution Approach 1:
The patent segments the delay time control from the Attack parameter control by introducing a separate timing control mechanism. The timing controller independently manages the delay time based on its own parameters (threshold level and timing parameter) rather than being solely dependent on the Attack parameter, enabling independent control of delay time while maintaining operational simplicity.
2Adaptability or versatility
If delay time is inversely proportional to rising speed of log level codes, then the control is uniform, but the delay time is uniquely determined and cannot be freely controlled
Solution Approach 1:
The patent implements dynamic control of delay time by allowing the timing parameter to be adjusted independently from the Attack parameter. The timing controller dynamically adapts the delay time based on the timing parameter value, enabling flexible control characteristics while maintaining the ability to achieve uniform control when needed through parameter selection.

AI summary
A dynamics processing method including receiving an input audio signal determining whether a level of the input audio signal exceeds a threshold value, determining whether a first amount of time, that is not specified to a unique value by a first speed at which a gain applied to the input audio signal is changed, has elapsed from when the level of the input audio signal exceeded the threshold value, and changing the gain applied to the input audio signal at the first speed.
