Silence the noise.

Founded in 1988 following research funded by the British Library National Sound Archive, CEDAR Audio invented real-time digital audio restoration — a technology the world said was impossible. More than three decades later, CEDAR remains the global standard for noise reduction, dialogue suppression and audio forensics in broadcast, post production, live sound and law enforcement.

About CEDAR Audio

The company that invented real-time audio restoration.

CEDAR Audio was established in Cambridge, UK in 1988 following five years of research funded by the British Library National Sound Archive. Its founders — including two Cambridge University Professors — set out to solve a problem the industry said was technically impossible: removing noise from audio recordings in real time without degrading the wanted signal.

They succeeded. Today, CEDAR is the only company in the world dedicated solely to audio restoration and speech enhancement. Its DNS (Dialogue Noise Suppressor) hardware is the broadcast industry standard; its CEDAR Cambridge platform is used in the world's leading archives and mastering studios; its Trinity and forensic tools are used by law enforcement and security agencies worldwide. CEDAR has received the Academy Award® for Technical Achievement, two Cinema Audio Society Awards and the Emmy®.

Available across MENA and Türkiye through MediaCast — in stock in Dubai, with demonstrations at the MCX Experience Centre in Barsha Heights.

Real-Time Hardware · DNS Series

The broadcast standard for dialogue noise suppression.

CEDAR's DNS hardware units are found in broadcast trucks, radio studios, dubbing stages and outside broadcast facilities worldwide. They remove unwanted background noise from speech in real time — at near-zero latency, with a single dial. No fingerprinting. No noise floor sampling. Just turn up the suppression.

Broadcast Standard
19" Rack · 8 Channel · Dante® AoIP

DNS 8D

Eight-channel dialogue noise suppressor with Dante® audio-over-IP. The flagship DNS unit — installed in broadcast trucks, large-venue production rigs and IP-based broadcast facilities. Eight independent processing channels, full Dante networking for flexible routing, and CEDAR's LEARN adaptive algorithm that continuously tracks and responds to changing background noise levels. Each channel has its own suppression control; the DNS 8D can handle eight separate presenter positions simultaneously.

19" Rack · 8 Channel · Analogue + AES

DNS 8S

Eight-channel dialogue noise suppressor for live sound and broadcast environments where audio over IP is not required. Analogue and AES/EBU connectivity — the DNS 8S is designed for installations where simplicity, reliability and traditional routing are prioritised. Eight processing channels with individual suppression, the same LEARN adaptive algorithm as the DNS 8D, and a straightforward analogue signal chain from input to output. The installation choice for live events, theatre and traditional broadcast environments.

DNS 4

Portable four-channel dialogue noise suppressor for location sound and smaller broadcast setups. Compact enough for an ENG kit but powerful enough for full broadcast-quality suppression on four independent channels. CEDAR's LEARN algorithm, the same core DSP as the full rack units, in a field-ready format. For electronic news gathering, documentary production and location recording where background noise is unpredictable and variable.

Portable · 2 Channel

DNS 2

Two-channel portable dialogue noise suppressor — the entry point into CEDAR hardware for location sound professionals. Two independent processing channels in a compact unit that fits in a sound bag alongside a mixer or recorder. Widely used for interviews, corporate video production, documentary work and broadcast ENG where two channels — often a lavalier and a boom — need CEDAR-quality noise suppression in the field.

Technology

What makes CEDAR different.

The technologies that define CEDAR's approach to noise suppression — and why professional broadcasters, post facilities and archives worldwide choose CEDAR over alternatives.

🧠
LEARN Algorithm

No noise fingerprint required

CEDAR's LEARN technology continuously calculates an adapting estimate of the background noise level, determining suitable attenuation at each frequency — without requiring a noise sample. Switch it on; it adapts to whatever conditions exist and continue to change.

⚡
Near-Zero Latency

Real-time processing, imperceptible delay

All CEDAR hardware operates at near-zero latency — the processing delay is imperceptible in live broadcast and events contexts. Presenters hear their processed audio in their earpiece without the latency that ruins live IFB monitoring.

🎯
Artefact-Free Processing

Speech preserved. Noise removed.

CEDAR's processing suppresses noise without introducing the musical noise, bubbling or distortion artefacts that characterise cheaper noise reduction tools. The wanted signal comes through clean and natural — not processed. This is the distinction that has earned CEDAR its industry accolades.

🔗
Dante® Networking

IP audio integration for modern facilities

The DNS 8D integrates with Dante audio-over-IP networks — allowing CEDAR processing to be deployed anywhere in a networked facility without fixed cabling. Route signals to the DNS 8D from any Dante-enabled device on the network and return processed audio to any destination.

🏆
Academy Award® Winning

Recognised by the film and broadcast industry

CEDAR has received the Academy Award® for Technical Achievement, two Cinema Audio Society Awards and the Emmy® for contributions to broadcast technology. These are not marketing claims — they are independent professional recognitions of genuine technical achievement from CEDAR's peers.

🔬
Cambridge Research

University-linked academic foundation

CEDAR was founded following research at Cambridge University and maintains strong academic links — including two Cambridge University Professors and a Director of Studies among its directors. The company actively pursues research into new techniques in audio restoration and speech enhancement, ensuring CEDAR's DSP remains at the leading edge.
