Acoustic Echo Cancellation in a VoIP Network

Excerpt...In order to remove the echo, you need to model the characteristics of the speaker to microphone coupling path, also known as the echo path. There is a direct, “line-of-sight”, component, and there are other components due to reflections from walls and objects in objects in the proximity of the speaker and microphone. The accuracy of the echo model that you create is best if you have a clear, undistorted measure of the signal going to the speaker as well as the signal coming from the microphone. The “closer” you are to the speaker and microphone, the fewer sources of distortion there will be.

THE HIGH PERFORMANCE ECHO CANCELLER FOR ASTERISK VOIP SYSTEMS

Excerpt...This article begins with a brief overview of echo in the telephone network. Then we’ll turn to echo cancellation as it pertains to Asterisk in particular. Then we will introduce the High Performance Echo Canceller (HPEC) that is now being deployed in Asterisk systems and compare it with the legacy Asterisk echo canceller.  While comparing the legacy Asterisk echo canceller with the HPEC, we introduce many terms that need further explanation. The final portion of the article is therefore devoted to describing these features and the echo issues that necessitate the use of these features.

High Density IP Voice Conferencing with Mixed Narrowband and Wideband Channelsby Scott Kurtz

The leap from traditional voice conferencing to IP-enabled voice conferencing brings with it a number of technical challenges that need addressing. We’ll start by describing the state of the art in traditional conferencing algorithms. Next, we’ll discuss the challenges that must be overcome in taking the leap to IP conferencing. Then, we’ll piece together an IP conferencing system on a DSP chip. We’ll conclude by listing the capabilities of a few Texas Instruments DSP chips in terms of conferencing channels and features that each can support.

by Scott Kurtz

The time has come for Open Source to do for Digital Signal Processing (DSP) applications what it has
already done for other software applications: allow developers to leverage proven software yet still customize it to their particular applications. DSP applications bring with them some unique challenges with respect to Open Source, but with unique challenges come creative solutions.
