1 Andrea Electronics Corporation Presents Array Microphone Products and Technologies for the Internet of Things 2018

2 Our History of Audio Innovation Founded in 1934 by Radio Pioneer Frank A.D. Andrea, Sr. Introduced the first Television at the 1939 New York Worlds Fair Andrea audio system chosen for the first manned Mercury spaceflights Andrea audio avionics systems in F16s, C130s and Black Hawk helicopters Became a Public Corporation in Ticker Symbol: ANDR

3 Pioneering Digital Microphone Products First USB Computer Headsets IBM Via Voice, DNS, L&H Voice Express Apple Computers Highest Performance Rated Microphone Nuance Dragon Naturally Speaking Nuance Dragon Naturally Speaking Millions of headsets sold

4 First Array Microphone Computer Products for OEMs OEM Hardware Creative Labs Web Cameras IBM ThinkPad Accessory Samsung Tablet PC Embedded Software Asus 1 Million array microphone accessories shipped Intel, Dell, and HP Over ½ Billion software units shipped IBM Ultraport Microphone

5 Noise Reduction Technology Andrea s patented PureAudio is an award winning wide bandwidth noise reduction sound enhancement algorithm. The performance is adjustable from 5 40dB and in significantly improves intelligibility of voice and audio in real world noisy environments.

6 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.

7 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, thusproviding a "video follow audio" capability.

8 DFTA continued Our Ring array with six microphones provides a typical beam width of 30º. Beam steering can operate over 360 degrees in increments as fine as a fraction of a degree.

9 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.

10 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. And our Far Field Field Enhancement (FFE) compensates for weak audio signals when speaking from long distances.

11 Hands Free Products and Accessories Andrea s flexible Array Microphone configurations achieve superior barge in and voice command & control for hands free operation of many embedded IoT devices such as; Smart Phone, Smart Speaker, Set Top Box, Docking Station, Home automation or Automotive applications.

12 PureAudio-Plus Audio Recording App with Integrated Filters Demo Andrea audio filters can be integrated and controlled by any mobile video recording or audio input application. Stereo microphone channels are required for beam forming and binaural 3D surround sound recording.

13 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

14 Andrea Electronics Value Proposition Andrea s OEM business model provides array microphone input solutions via software licensing and hardware component sales. Our latest filter libraries are designed for OEMs targeting new product platforms running Linux and Android operating systems, while utilizing new low power mobile processors. Portable and scalable, Low MIPs, small memory, adaptive/no tuning, robust, proven for mass production.
