DNS

A world standard for dialogue noise suppression

CEDAR Cambridge DNS dialogue noise suppressor

Designed to clean up noisy dialogue, the Academy Award® winning DNS processes splits the signal into a large number of well-defined bands, and sophisticated digital filters then analyse each of these, suppressing the noise independently in each. The innovative design of the filter bank allows you to control DNS using relatively few controls, making it simple and quick to use in all situations.

DNS with LEARN...

A further development of the groundbreaking algorithm contained within our award-winning DNS 8 Live dialogue noise suppressor, LEARN allows DNS to calculate a remarkably accurate adapting estimate of the background noise and determine suitable noise attenuations at each frequency for optimum suppression. It's not a noise fingerprint and you do not need to find a section of the audio that contains little or no wanted signal to take a noise measurement. Yes, you can use it to take a snapshot of existing conditions and then fine-tune the parameters, but it's also possible to leave it switched on so that it can adapt to changes in the background and surroundings. It not only adapts in a fraction of a second to changes, it differentiates between the wanted signal and the noise so that you obtain superb noise suppression at all times.

If you work with film dialogue, the speed, flexibility, and ease of use of DNS provides solutions to audio problems that you could not previously solve. And, with eight channels DNS in a convenient, automated format, it's ideal for multi-channel post-production in the film, video, and TV industries. Elsewhere, in the audio forensic laboratory, DNS is used widely for removing motor noise from small covert recorders, for eliminating electrical interference, and for helping to clean up recordings suffering from unfavourable acoustics and poor microphone locations.
