Overview: The QuiteQuiet Acoustic Echo Cancellation(AEC) software is an implementaiton of the AT[and]T-patented AEC technology. QuiteQuiet AEC technology cancels acoustic echoes arising in two-way and multipoint hands-free telephony, providing high-quality, full-duplex speech communications for a wide variety of teleconferencing and video-conferencing applications.
Ideal Performance: Ideal for teleconferencing and videoconferencing or any application requiring hands-free audio.
Algorithm Verification: QuiteQuiet AEC performance specifications are compatible with the ITU's G.165 and G.167 series recommendations on echo cancellers for telephony.
Availability: Available as object code for the 'C31. Also available as a self-contained module.
