Revolabs today announced it has improved the acoustic echo canceller (AEC) technology in its FLX UC line of conference phones to support up to 16 kHz audio. The enhanced echo cancellation allows the microphones to match the performance of the dual-speaker system in the FLX UC product line, creating a robust, high-performance audio platform for UC that allows users to hear every word in a conference call.
AEC is the technology that allows bi-directional, 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 now, with more information here.
