Abstract
Official abstract text for this publication.
Methods and apparatus for generating an anti-noise signal and equalizing a reproduced audio signal (e.g., a far-end telephone signal) are described, wherein the generating and the equalizing are both based on information from an acoustic error signal.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of processing a reproduced audio signal, said method comprising performing each of the following acts within a device that is configured to process audio signals: based on information from a noise estimate, boosting an amplitude of at least one frequency subband of the reproduced audio signal relative to an amplitude of at least one other frequency subband of the reproduced audio signal to produce an equalized audio signal; performing an ech…
