In addition, PC's may be used in high noise level environments which can affect the performance of applications, such as those that use speech input. Andrea's PureAudio USB-SA with patented noise reduction technology eliminates noise problems as it utilizes high quality digital circuitry and has state of the art noise reduction algorithm software. This format bypasses your desktop or laptop computer's sound system, providing increased intelligibility and performance of stereo microphone input and stereo speaker output for all of your digital audio applications including VoIP and speech recognition programs.
