Biamp Introduces Sona AEC Algorithm at ISE 2010

Biamp Systems has introduced Sona, its latest innovation in acoustic echo cancellation algorithms. Sona offers features, which the company says will deliver enhanced audio quality - even in the most challenging acoustical environments - while also providing increased efficiencies for integrators when installing audio networks.


The Sona AEC algorithm is now availablein AudiaFLEX AEC-2HD cards, Nexia VC (videoconferencing) and Nexia TC(teleconferencing) processors.

In addition to true 20Hz to 20 kHzwideband AEC, Sona introduces the following benefits:

· Longer tail length - The taillength available with Sona is up to 300 milliseconds. This means thatconference sessions can be held in larger rooms or evenacoustically-challenging environments and participants willexperience clear, crisp, echo-free audio.

· Faster convergence - The time toconverge is faster with Sona than with other algorithms on themarket. As a result, echo-free audio will be maintained under almostevery condition, such as at conference start-up, when a microphone ismoved, when a participant enters or leaves the room, or if someoneopens or closes a window or door.

· Enhanced performance - Sona isless sensitive to changes in gain structure than other systems. As aresult, it is easier to set up and install, saving the integratoreffort, time and cost.
