Abstract
Official abstract text for this publication.
Psychoacoustic Bass Enhancement (PBE) is integrated with one or more other audio processing techniques, such as active noise cancellation (ANC), and/or receive voice enhancement (RVE), leveraging each technique to achieve improved audio output. This approach can be advantageous for improving the performance of headset speakers, which often lack adequate low-frequency response to effectively support ANC.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus, comprising: an active noise cancellation (ANC) module; and a psychoacoustic bass enhancement (PBE) module configured to produce a PBE signal based on output from the ANC module. 2. The apparatus of claim 1 , wherein the PBE module is configured to produce the PBE signal based on an audio signal and the output from the ANC module. 3. The apparatus of claim 1 , further comprising: a control module co…
