Additionally, the HD AEC acoustic echo canceller is effective in improving the performance of speech recognition algorithms when operating in an echoic environments.Īctive hybrid circuits provide some echo reduction, but not enough when the end-to-end circuit delay is even moderate.
The HD AEC algorithm eliminates acoustic echo in difficult conditions such as unbalanced speech levels, close speaker to mic proximity, background noise, wind noise, double talk, and echo path changes.Īdaptive Digital’s HD AEC acoustic echo cancellation technology can be found in a wide range of applications, like IP Intercom Systems, Conference Speakerphones for both large and small conference rooms/huddle rooms, IP Desk Phones, Mobile Handsets, Radio over IP, and essentially anywhere where voice quality is affected by adverse room conditions.

HD AEC has, has integrated both Noise Reduction, and Automatic Gain Control (AGC) into its AEC algorithm.Īdaptive Digital’s HD AEC software product provides superior voice clarity and true full duplex performance enabling simultaneous communication with no delay under a wide range of acoustic environments for both outdoor and indoor applications.Īdaptive Digital uses a proprietary fast converging adaptive filter, and non-linear processor to deliver robust double talk performance both indoors and even in unpredictable outdoor conditions.

Acoustic Echo Cancellation (AEC ) is used to cancel acoustic feedback between a speaker and a microphone in loud-speaking audio systems, teleconferencing devices, hands free mobile devices, and voice-controlled systems.Īdaptive Digital’s high definition acoustic echo canceller (HD AEC™) is exceptional at handling echo.
