Because the AST800 delivers robust acoustic echo and noise cancellation performance, it is often used instead of the video conferencing codec's microphone and acoustic echo canceller. Industry-leading acoustic echo cancellation technology prevents received audio from being retransmitted to its original location. Patented noise cancellation algorithms dramatically reduce ambient noise in the audio sent to other sites. User-adjustable, neural network Automatic Gain Control (AGC) reacts only to valid speech patterns, bringing voices within desired levels.
