Abstract: Remote conferencing using desktop workstations is becoming commonplace. Typical audio conferencing hardware consists of a room loudspeaker (often built into the workstation) and a stand-alone microphone. Because there can be strong coupling between the loudspeaker and mike, undesirable echo signals can result. We propose to eliminate these signals using well understood echo cancellation algorithms running on a vendor-supplied, off-board DSP coprocessor. We have extended the Ptolemy code... (Update)
