Broadband noise reduction

CEDAR Cambridge broadband noise reduction

There's a tendency to think that digital dehissers are all equal - magical processors that somehow remove all of the noise without any side-effects or damage to the wanted audio. This isn't true; it's quite easy to remove noise, but it's very difficult to do so without introducing strange artefacts, and even more difficult to do without reducing the high frequency content of the wanted audio or introducing unwanted compression.

CEDAR's 'NR' and Auto Dehiss processes are based upon a sophisticated core algorithm than concentrates on minimising artefacts, dullness and compression. These have been used on countless music tracks, film and TV soundtracks, forensic recordings and much more.

The processes:
