Superbeam SoundMAX Array Microphone

Andrea Electronics digital microphone products and technologies enable more accurate and reliable communication as well as high performance speech recognition in noisy office environments.

Product Features

- Compatible with most stereo digital audio recorders (with plug in power mic inputs), and Andrea USB-SA audio adapter

- Sleek, stylish two-microphone design (4.3 inches length, 1.7 inches width, 0.9 inches deep). Unsurpassed in performance. Unprecedented price point.

- The Andrea Array is a far-field, 2-microphone array with stereo output.

- Offers the highest quality and performance of a low cost upgrade over a single element microphone.

- Small size for unobtrusive mounting on a monitor or laptop.

- Specifically designed for use with Andrea DSDA, and PureAudio noise reduction software running on the host processor to enable untethered:

- Continuous Speech Recognition

- Command and Control

- Voice over IP Internet Telephony

- Andrea’s DSDA and PureAudio noise canceling algorithms allow for superior audio quality by cancelling out background noise resulting in increased intelligibility of communications.

- Compatible with Andrea’s AudioCommander audio interface software to optimize multimedia control applications. AudioCommander is available at www.AndreaElectronics.com.
