Noise Reduction Technology

Andrea’s patented PureAudio™ is an award winning wide bandwidth noisereduction sound enhancement algorithm. The performance is adjustable from 5‐40dB and in significantly improves intelligibility of voice and audio in real world noisy environments.  

Array Microphone Technology

Andrea’s patented DSDA™ (Digital Super Directional Array) adaptive beam forming algorithm can work with 2 or up to 8 microphones which can be in a linear/broadside format or circular geometry. The beam enables more directional audio pickup toward the voice source while reducing background sounds outside of the beam.

Direction Finding & Tracking Array

Andrea's Patented Direction Finding and Tracking Array (DFTA™) technology utilizes an array of microphones and an adjustable algorithm that detects the presence of a user's voice, determines the direction of the voice and follows and tracks it when it moves.  In a videoconferencing setting, this unique technology can provide direction to a videoconferencing camera and allow the system to steer and concentrate on the speaker, thus providing a "video‐follow‐audio" capabilitythus providing a  video follow audio  capability. 

DFTA continued

Our Ring array with six microphones provides a typical beam width of 30º.  B i 360 d i i fiBeam steering can operate over 360 degrees in increments as fine as a fraction of a degree.

Full Duplex Acoustic Echo Cancelation

Andrea’s patented EchoStop™ provides a full duplex acoustic echo cancellation algorithm enabling a high quality speakerphone for far field communications. Adaptive processing reacts to any changes in the environment maintaining consistent performance.

Barge-In and Far Field Enhancement

Our new software library runs on the Raspberry Pi micro computer enabling Voice trigger/Barge‐in  the same feature found on products like the Amazon echo.  A d Far Field Enhancement (FFE) t f k di i l hAnd our Far‐Field Enhancement (FFE) compensates for weak audio signals when speaking from long distances. 

Hands Free Products and Accessories

Andrea’s flexible Array Microphone configurations achieve superior barge‐in and voicecommand & control for hands‐free operation of many embedded IoT devices such as;Smart Phone Smart Speaker Set Top Box Docking Station Home automation orSmart Phone, Smart Speaker, Set Top Box, Docking Station, Home automation orAutomotive applications.

PureAudio-Plus Audio Recording App with Integrated Filters Demo

Andrea audio filters can be integrated and controlled by any mobile video recording or audioinput application.

Stereo microphone channels are required for beam forming and binaural 3D surround soundrecording.

DA-250 Standalone Array Microphone Module

The DA‐250 is a small Compact Stereo Array Microphone and 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, but in the past has been unattainable with an embedded microphone configuration
