Problems solved by technology

[0006] However, depending on hardware limitations, such nonlinear quantizers may not have sufficient resolution for low-amplitude signals to suppress audible quantization noise
This problem is especially pronounced when the codec employs noise shaping techniques that use insufficient oversampling ratios (OSR), such as sigma-delta modulation

Abstract

An apparatus and method for processing signals are disclosed. The apparatus may include a receiver configured to receive an audio signal having a plurality of audio artifacts, and an audio circuit configured to reduce the audio artifacts during at least a portion of a time period as a function of an energy level of the audio signal during that time period.

Description

[0001] Claim of priority under 35 U.S.C. §119 [0002] This patent application claims priority to Provisional Application No. 61 / 083,454, filed July 24, 2008, entitled "METHOD AND APPARATUS FOR REDUCING AUDIO ARTIFACTS," which The case has been assigned to the assignee of the present case and is hereby expressly incorporated herein by reference. Background technique [0003] The present invention relates generally to communication systems, and more particularly to concepts and techniques for reducing audio artifacts. [0004] Peer-to-peer networks are typically used to connect wireless nodes via dedicated connections. These networks differ from the traditional client-server model where communication is usually with a central server. A peer-to-peer network has only peer nodes that communicate directly with each other. Such networks are useful for many purposes. The peer-to-peer network can be used, for example, as a consumer wire replacement system for short-range applicat...
