The DNS 2 Two-Channel Dialogue Noise Suppressor from CEDAR is a small, convenient, and simple to use portable noise suppressor. It features CEDAR's DNS algorithm, together with the unique learn function that calculates the noise content within a signal and determines optimum parameters to attenuate the noise, while maintaining the wanted signal. It can be used to eliminate traffic noise, air conditioning, wind, rain, babble, and general background noise from audio signals in real-time applications.

The DNS 2 requires nothing more than switching on the learn function that identifies and adapts to the background noise and dialing in the amount of noise attenuation required. It offers near-zero latency and is suitable for use in all situations, from location recordings and live-to-air broadcasting, to live sound in venues such as theaters, concert halls, conferences venues, and places of worship, as well as studio work and post production houses.
