Your headset, microphone or speakers will perform only as good as the sound card or integrated audio system that you plug into. Most laptops and PCs today have audio systems built in and it is often placed close to noisy components like the power supply or high frequency processors. 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.

PureAudio® is a noise canceling algorithm that enhances speech-centric applications by sampling an ambient noise environment and attenuating the noise sources around the desired speech signals, delivering a pure audio signal. Continuous and repetitive noise is effectively removed from the audio input, providing higher recognition rates and improved communications.  Designed specifically to improve signal-to-noise ratio, PureAudio works best in canceling stationary noises such as computer fans, engines, tire noise, etc.
