Abstract
Official abstract text for this publication.
Systems, methods, and devices are disclosed. An example sound processor is disclosed. The example sound processor includes a module configured to identify a feedback artifact in a current sample of an input spectral component by determining that a change in a signal level of an input spectral component is approximately equal to a predicted change. The predicted change may be based on one or more characteristics of an external feedback loop. Responsive to identifying the feedback artifact, the sound processor is further configured to apply a modification to a parameter used to process the input spectral component. The modification reduces a likelihood of including audible feedback in a processed input spectral component.
First claim
Opening claim text (preview).
What is claimed is: 1. A sound processor configured to: identify a feedback artifact in a current sample of an input spectral component by determining that a change in a signal level of the input spectral component is approximately equal to a predicted change; and responsive to identifying the feedback artifact, apply a modification to a parameter used to process the current sample of the input spectral component, wherein the modification reduces a likelihood of including audibl…
