CEDAR DNS hardware units are still the primary resource for many television studios that need a solution for common noise problems.

When discussing the BBC production, The Choir, Alex Wrigglesworth, who also works on programs for ITV, BT Sport and Channel 4 told us, “I tend to use CEDAR across most of the stuff that I do, whether it’s live or pre-recorded, but I don’t often use more than around two or three dBs of reduction.”

In this video, Cameron Van Dijken, Broadcast Engineer at Web3 Productions in Dubai, explains why having an 8-channel, near zero-latency noise reduction unit is highly beneficial to his workflow and final deliverables.

Ambience tracks are a tapestry of different sounds, but not every element fits the story you’re trying to tell.

CEDAR Retouch gives you the precision to target individual elements within a recording and remove only what you don’t need.

Machinery, passing vehicles and the surrounding environment can all interfere with dialogue recording. Effective noise reduction helps you preserve the original performance and avoid unnecessary ADR.

You wouldn't normally encounter industrial locations like this on a shoot, but this example shows what's possible pushing VoicEX 2 to its limits with challenging location sound that you might not have the time or budget to replace.

Noise reduction on location isn’t just about removing unwanted background noise; it’s just as important to preserve natural dialogue, tonal quality and clarity without introducing unwanted artefacts.

You’re unlikely to shoot a scene somewhere this loud, but we wanted to push VoicEX 2 to show what it can do.

VoicEX 2 has helped turn otherwise unusable audio into usable recordings for reality TV and documentaries, where you have less control over the recording environment.
