Stereo Acoustic Echo Control Using A Simplified Echo Path Model

Christof Faller, Christophe Tournery

In handsfree tele- or video-communication, acoustic echoes arise due to the coupling between the loudspeakers and microphones. It is much more challenging to remove the undesired acoustic echoes for stereo or multi-channel tele-communication systems than f ...

Improved Time Delay Analysis/Synthesis for Parametric Stereo Audio Coding

Christof Faller, Christophe Tournery

For parametric stereo and multi-channel audio coding, it has been proposed to use level difference, time difference, and coherence cues between audio channels to represent the perceptual spatial features of stereo and multi-channel audio signals. In practi ...

Robust Acoustic Echo Control Using a Simple Echo Path Model

Christof Faller, Christophe Tournery

In handsfree tele or video conferencing acoustic echoes arise due to the coupling between the loudspeaker and microphone. Usually an acoustic echo canceler (AEC) is used for eliminating the undesired echoes. The weaknesses of AEC are that it is relatively ...
