Andrea Electronics Revolutionizes PC Sound Quality With Debut Of New High Fidelity USB Sound Card

PureAudio™ USB-SA Affordably Transforms PC Sounds into Premium Audio [The following is a release from Andrea Electronics]

September 19, 2008

Andrea Electronics Corporation (OTCBB: ANDR), a leading developer of active noise cancelation technologies, today introduced the PureAudio USB High Fidelity External Sound Card (USB-SA) to substantially improve the quality of PC audio sound. Designed to transform ordinary audio input and output from built-in sound cards shipped standard on PCs, desktops and laptops, the USB-SA uses Andrea's patented noise canceling technology and innovation to dramatically improve the quality of audio sound for portable computing. Traditional technologies have produced sounds that are only as good as the sound card that ships standard on a PC. Often located near high electrical noise circuitry such as the power supply or high frequency processors, typical sound cards are impacted with a significant degradation of sound. Andrea's new USB-SA device replaces the computer's existing integrated sound system and eliminates external noise, simultaneously increasing both the intelligibility and performance of stereo microphone input and stereo speaker output. "Whether you are using VoIP applications on your computer, watching YouTube(TM) movie clips, using game chat, or simply listening to music, quality audio is increasingly an essential element of being online," said Douglas Andrea, CEO of Andrea Electronics. "Improving PC clarity and audio performance is fast becoming a requirement for both consumers and enterprises alike. The market is increasingly looking for affordable solutions to improve audio quality." Andrea's USB-SA provides digitally enhanced sound by filtering specific audio parameters including the quality of transmit and receive, eliminating distortion and acoustic echo to deliver the high-performance required by speech recognition applications such as Dragon(R) Naturally Speaking(R) or for use with popular VoIP internet phone applications such as Skype(TM), Microsoft's MSN Messenger(TM), and Google Talk. The size of a thumb drive, Andrea's USB device is designed to have a superior digital noise floor that can be used to enhance the sound of any existing legacy headset, microphone or speakers resulting in transforming the sound into a cleaner and stronger signal for the most optimal audio fidelity available for the headset, microphone or speakers. "We were immediately impressed by the compact size and the quality. The full duplex device isn't just a petite pretty face. It produced the lowest noise floor of any previous soundcard we've tested." said Lunis Orcutt of KnowBrainer, value added reseller of speech recognition equipment and software. "The USB-SA seems to be well thought out and attractively priced. Some of the microphones that we sell have difficulty with full duplex USB Pods but none have a problem with the USB-SA, which is now our favorite." The Andrea PureAudio Voice Solutions Software Suite The USB-SA utilizes Andrea's patented PureAudio Voice Solutions Software Suite, complete with Pure Audio, EchoStop, Digital Super Directional Array (DSDA), Audio Commander and Voice Center, using Digital Signal Processing (DSP) technologies to improve the sound quality, marking a significant leap forward in enhanced sound technology. Andrea's digital audio software, combined with the circuitry in the USB, enhances and customizes the signal using a number of Andrea patented technologies: -- Andrea's PureAudio patented and award-winning noise reduction speech enhancement algorithm is designed for hi-fidelity sound quality and significantly improves accuracy in speech recognition applications, especially in environments with significant ambient noise. The algorithm also filters incoming audio and enhances the clarity of the received audio signal. -- Andrea's EchoStop(TM) patented full duplex acoustic echo cancellation algorithm lets the speaker broadcast and microphone transmit simultaneously. -- Andrea's DSDA(TM) patented Digital Super Directional Array adaptive beam forming system contains Andrea's SuperBeam Technology to deliver more intelligible audio sound by eliminating annoying background noise from video conferencing and speakerphone functions. It forms a beam around the speaker and eliminates background noises that are outside the parameters of that beam. -- Andrea's Audio Commander Software provides a PC Audio Control Panel for controlling microphone and speaker volume, a 10-band graphic equalizer with 18 built-in presets and PureAudio noise reduction control. -- Andrea's Voice Center digital audio/voice recording software has unlimited recording time compressed audio/voice files (WMA format) that can be sent via e-mail or by dragging-and-dropping audio or other voice files into Microsoft Word, PowerPoint and other applications that support audio functionality. Andrea's SuperBeam Stereo Array Microphone The Andrea SuperBeam Stereo Array Microphone enables users in small office/home office (SoHo) settings to use Internet telephony, enhance audio/video-conferencing and continuous speech recognition applications, with high quality voice input and without the use of a headset or handset. The SuperBeam Microphone was specifically designed for use with the Andrea DSDA beam forming audio input software and provides far field speech recognition with the same accuracy of a close talking headset. Availability The USB-SA is available now and retails for US MSRP of $44.95. Andrea Electronics Corporation is offering the USB-SA (MSRP US $44.95) combined with the SuperBeam Array Microphone (MSRP US $34.95) for a combined price of US $49.95 (a $79.90 value) For more information about Andrea's PureAudio USB-SA and a complete list of product specifications visit http://www.andreaelectronics.com/Buy/ProductDesc/USB-SA.htm.
