Andrea Communications EDU-USB eliminates the noise problems that are inherent in most standard, off-the-shelf computers.

Often placed in close proximity to components such as the power supply and processors, internal sound cards or integrated audio systems can generate audible noise. Combine this with the fact that computers are frequently used in high noise level environments, and the performance of peripherals like headsets, microphones, and speakers may be affected.

The EDU-USB uses high quality digital circuitry to bypass the computer's internal sound system, converting the analog signal to digital. The result is increased clarity and performance of both the stereo microphone input and the stereo speaker output for all digital audio applications including VoIP and speech recognition programs.
