Digital Array Microphones and Noise-Reduction SolutionsDA-250Q OEM Array Microphone-Speakerphone Noise Canceling Software
Product Description Noise Canceling Software
The DA-250Q is a compact Stereo Array Microphone Digital Signal Processor (DSP) circuit board platform that can easily be integrated into many different OEM devices that would greatly benefit from directional noise canceling microphone performance and full duplex acoustic echo cancelation for speakerphone functionality.
Requiring only two tiny holes in the faceplate of a device, the DA-250Q OEM Array Microphone can deliver directional microphone sensitivity without the need for acoustic baffling, as found in large parabolic waveguides or long shotgun tube type microphones.
System Configurations: Stereo Array Mic w/DSDA Beam Forming, PureAudio Noise Reduction, EchoStop full duplex acoustic echo cancellation and Far-Field Enhancement for increasing weak voice signals.

Product Description Noise Canceling Software
The USB-PA Array Microphone provides a USB digital audio adapter to bypasses the computer’s standard integrated sound system, providing a high fidelity/low noise digital audio platform. The product comes with the stereo Array-PA Microphone.
This external audio system utilizes the computers central processor to run Andrea’s Audio Filters Software with adaptive beam forming and noise reduction.
Compatible with Windows, Mac, and Linux OS.
Product Description Raspberry Pi Microphone
For developers looking to enable voice recognition, a high-performance microphone and advanced noise-canceling software are vital for optimal performance and successful trigger-phrase detection.
A common problem with trigger-phrase detection is being able to detect the trigger-phrase when music is playing out of the speaker, located near the microphone. This is known as barging-in to the music in order to speak commands to the device.
The data below documents how Andrea’s audio filters significantly improve the barge-in performance of any speech recognition device, making the PureAudio™ Array Microphone the ideal microphone.
