[. . . ] Tesira ® SEC-4 4-Channel Mic/Line Modular Input Card with Acoustic Echo Cancellation DATA SHEET
The Tesira® SEC-4 is a modular analog input card for use with Tesira SERVER or SERVER-IO devices. [. . . ] The card also features two new Biamp algorithms, SpeechSenseTM and AmbientSenseTM which enhance speech processing by more accurately distinguishing between human speech and noise. Software control is separated into separate blocks for mic/line inputs and AEC processing. This allows the system designer to use the inputs independent of the AEC processing, and apply the AEC algorithm to inputs from a different part of the system. The SEC-4 also includes processing for Automatic Gain Control, high pass filter and noise reduction.
