Noise Suppression Plugins
Suppress background noise instantly on-location with the optional CEDAR sdnx or Sound Devices NoiseAssist plugins for 8-Series
mixer-recorders.
CEDAR sdnx
Over the last few decades, CEDAR has become synonymous with real-time, low-latency, and artifact-free audio restoration and
noise suppression. CEDAR Audio Ltd.’s sdnx brings CEDAR’s highly-regarded noise suppression technology to 8-Series
mixer-recorders. This optional plugin reduces unwanted background noises so you can better capture dialog.
CEDAR sdnx has near-zero latency and one simple control for adjusting the amount of suppression. Up to 8 instances of CEDAR
sdnx are available per mixer-recorder/device. These instances can run on any combination of isolated channels or bus. The plugin
functions at sample rates up to and including 96 kHz.
Previously, using CEDAR with an 8-Series mixer-recorder required a separate hardware unit like the CEDAR DNS 2. This
collaboration between CEDAR and Sound Devices marks the first time CEDAR technology has been available in-unit for any
portable mixer-recorder. Now, even ultra-light portable recording setups have access to CEDAR noise suppression.
CEDAR sdnx requires 8-Series firmware v7.40 or higher. Want to try before you buy? The 2-instance version of the plugin is
available as a demo on 8-Series running v7.40 or higher.
Sound Devices NoiseAssist
NoiseAssist is an advanced signal processing algorithm that reduces background noises such as traffic, generators, HVAC noise,
and more. The plugins continuously monitor background noise to give you clean audio for the entire take.
Using NoiseAssist is easy and fast - simply adjust the amount of background noise to suppress and NoiseAssist will do the rest.
Suppression happens in real time with just 1 ms of latency - no “learning” required. Depending on the plugin purchased, two-, four-,
or eight- instances of NoiseAssist can run on any combination of isolated channels and/or any bus.
This algorithm is optimized specifically for high-end professional film and television dialog. It accurately distinguishes the desired
speech signal from background noise using proprietary advanced multi-band frequency, level, and statistical calculations.
NoiseAssist maintains the excellent frequency bandwidth of the audio channel, while effectively suppressing the background noise
and reverberation.
NoiseAssist Plugins are available for purchase at store.sounddevices.com
Try the two-instance version of NoiseAssist Plugin in demo mode (tone bursts replace audio every 10 seconds) until the NoiseAssist
Plugin license is purchased and installed. The NoiseAssist demo mode is disabled when the 8-Series is powered down.
