Sound Effect Device Muting Mechanism for Discontinuity Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sound effect devices using digital signal processors experience discontinuous output when switching effects, leading to sound breaks and an unnatural listening experience.
Innovation Solution
An effect imparting device with multiple units, a storage system for patches of parameters, an input mechanism for patch designation, an application part for parameter application, an output part for processed sound, and a muting mechanism that temporarily mutes sound when effect type changes occur, minimizing discontinuity by applying known coefficient interpolation processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If effects are switched by loading corresponding programs in a DSP-based effector, then the ability to change effect types is improved, but the output sound becomes discontinuous causing sound breaks
Solution Approach 1:
The system performs preliminary detection of effect type changes before switching effects. The determination unit identifies when an effect type change will occur, and the muting unit pre-mutes the output signal in advance, preventing sound breaks from occurring during the effect switching process.
Solution Approach 2:
The muting unit acts as an intermediary between the effect switching mechanism and the output. By introducing this intermediate control element, the system can manage the transition between different effect types while maintaining continuous, break-free sound output.
2Reliability
If muting is performed whenever patch designation changes, then sound breaks are prevented, but unnecessary muting occurs when only parameters change without effect type change
Solution Approach 1:
The determination unit applies different treatment to different aspects of effect parameters. It specifically identifies when effect types change versus when only other parameters change, applying muting only in the local case of effect type changes rather than all parameter changes, thus avoiding unnecessary sound interruptions.
Solution Approach 2:
The system distinguishes between different types of parameter changes - specifically separating effect type changes from other parameter changes. By detecting only effect type changes as the trigger for muting, the system maintains natural sound continuity for parameter adjustments that don't involve effect type transitions.
3Reliability
If a bypass path for original sound is arranged to suppress sound breaks, then device complexity increases with additional paths, but sound continuity is improved
Solution Approach 1:
The invention extracts the essential function needed for continuous sound output - the muting capability - and separates it from the effect switching mechanism. Rather than adding complex bypass paths, the system extracts and applies a simple muting function controlled by effect type change detection, reducing overall system complexity.

AI summary
An effect imparting device, control method and non-transitory computer readable medium are provided. This effect imparting device has: a plurality of effect units that provide effects to a sound that has been input; a storage part for storing a plurality of patches each including a collection of parameters to be applied to the effect units; an input part for receives a designation of a patch; an application part for applying the parameters included in the designated patch to the effect units; an output part for outputting the sound to which effects have been provided in accordance with the parameters applied to the effect units; and a muting means for temporarily muting the effects—provided sound to be outputted when the effects units include an effect unit in which the type of an effect is changed through changing of the designated patch.
