We're big fans of classic R&B here at CEDAR, and so it's great to see the legendary O'Jays still bringing it to audiences around the world.

Every night, Front of House engineer Joel McCarthy relies on the CEDAR DNS 8D to deliver a pristine audio signal to the audience, eliminating mic bleed, HVAC noise, electrical hum and feedback.

If you haven't experienced its performance yet...join the love train!

CEDAR plug-ins are impressive on their own, but once you get to know them you might find ways to stack them and achieve even more impressive results!
In this audio example, the dialogue is mixed in with large amount of background noise that we are able to completely eliminate with combination of the following noise reduction processes:
Debuzz - to intelligently target the electronic buzz and it’s harmonics.
VoiceEx2 - to extract the voice from the voice using CEDAR’s neural net technology.
ScreenVox - for a final, transparent polish using a classical DSP process.

A demonstration of our most popular post-production dialogue noise suppressor. The DNS One algorithm first appeared in the Academy Award-winning DNS 1000 hardware, and has since been used on too many Hollywood blockbusters to mention!

We've consistently refined and improved the solution for modern workflows, offering very low CPU usage, zero latency and an automatic 'learn' function. This means you can use an almost unlimited number of instances across your DAW session, and it can even be used for live sound.

The DNS One is unbeatable when it comes to preserving a performer's voice.

This is noise reduction that adapts as you work.

ScreenVox delivers low-latency noise reduction that learns and adapts as the background noise changes, keeping speech clear and natural without the heavy load on your CPU.

Designed for live sound, broadcast and streaming, ScreenVox uses classical DSP and can run in DAWs, live plug-in engines and hardware hosts.

Listen to the difference it can make.

Managing noise from multiple microphones is all part of the job in broadcast audio, but it needn't be complicated.

The DNS 8 provides eight channels of dialogue noise suppression over Dante, with independent processing for each channel and the flexibility to route audio wherever you need it.
