Revolabs introduces echo cancellation for FLX UC conference phones

AUTHOR: Inavate

Revolabs has upgraded the acoustic echo canceller (AEC) technology in its FLX UC line of conference phones to support up to 16kHz audio.

The enhanced echo cancellation allows the microphones to match the performance of the dual-speaker system in the FLX UC product line, creating an audio platform for UC that allows users to hear every word in a conference call.

AEC is the technology that allows bidirectional, full-duplex audio in conference phones, enabling natural communication among a call's participants.

Because of the significant processing power and complex algorithms required for using ultra-wideband frequencies, many conference phones cut audio at 8 kHz or below, which results in an artificial-sounding user experience. The new echo cancellation implementation supports up to 16 kHz audio for more natural sound.

The FLX UC 500, UC 1000, and UC 1500 conference phones are shipping today with ultra-wideband echo cancellation. Existing customers with FLX UC 500, UC 1000, and UC 1500 units already installed can get the new echo canceller by downloading a free firmware upgrade from Revolabs' support website here
