SPIRIT Makes Headphones Needless with RealDuplex for VoIP Conferencing

8/18/2004 - SPIRIT (www.spiritdsp.com) announces RealDuplex for VoIP, its new software product targeted for PC-based VoIP conferencing. As acoustic echo is a common problem plaguing handsfree VoIP users with desktops and notebooks alike, eliminating this annoying factor is crucial for net conferencing. So far using headsets was the only solution for the issue, but now SPIRIT RealDuplex(tm) makes voice communication via PC/notebook speakers and microphone easily possible - even in noisy environments.

SPIRIT RealDuplex(tm), based on Advanced Acoustic Echo Cancellation and Noise Cancellation technologies, filters out all noise and echo effects and enables distortion-free full duplex voice communication. Regardless of how many people are speaking at the same time, RealDuplex(tm) -powered conferencing never degrades into a mess of random syllables and sounds.

To maintain the best voice quality possible, the system automatically switches to half-duplex mode when noise exceeds tolerable level, and reverts to full duplex as soon as noise drops back. Advanced AEC integrated in RealDuplex(tm) provides up to 60ms echo rejection allowing natural, full-duplex speech quality and relieving speaker from headphones and wires.

Thanks to SPIRIT RealDuplex, handsfree multipoint conferencing becomes reality - the participants can talk simultaneously without any distortions or breaks, allowing executive-level quality and user-friendliness for the personal and business communications.

Advanced noise cancellation makes SPIRIT RealDuplex(tm) perfect for mobile remote conferencing from any environment. Even when a lot of different noises get mixed with user's voice, such as car engine noise, other people speaking, laptop cooler and harddisk rumble, surrounding noises, etc., SPIRIT ensures highly intelligible and easy-to-understand speech quality.

SPIRIT RealDuplex(tm) can be also used in interactive online PC games for comfortable communication between players without echo effects and breaks.

"SPIRIT RealDuplex makes VoIP conferencing more effective as there's no need to repeat the same phrase several times to be heard. Now you are free to talk to people anywhere, no word would be missed or disrupted." - says Andrew Sviridenko, founding CEO of SPIRIT.
