Audio Echo and Noise cancelling board.

Developed using the latest DSP technology and software algorithms to provide a simple solution to some of the most annoying problems with audio systems.

The small board, 52mm x 44mm, provides clear audio output from a noisy environment and also greatly reduces the echo in a two way conversation.

The PCB provides simple shorting links to allow separate functions to be disabled as the application requires, below is the list of controllable functions.

• Gain control in both channels of a two channel audio system
• Echo and howl processing control
• Cross channel attenuation control
• Channel AGC control
• Noise level cancellation
• Channel bandwidth limiter

Also provided is a digital serial interface to allow microprocessor control of all DSP functionality and audio channel controls.
