Sound Devices Releases Firmware v7.40 for 8-Series Mixers featuring CEDAR Noise Suppression Technology

26th Jan 2021

Sound Devices announced a collaboration with CEDAR Audio Ltd. that delivers CEDAR noise suppression technology to 8-Series mixer-recorders. The CEDAR sdnx plugin for 8-Series is available for purchase at in versions with 2, 4, or 8 instances of suppression that can be inserted on any combination of channels and buses selected by the user. The plugin functions at sampling rates up to and including 96 kHz and has near-zero latency.

"Over the last few decades, CEDAR has become synonymous with real-time, low-latency, and artifact-free audio restoration and noise suppression. That's why sound professionals put their trust in them every day,” said Paul Isaacs, Director of Product Management and Design at Sound Devices. “We are super thrilled and honored to collaborate with the CEDAR team to bring their highly-regarded noise suppression technology to our 8-Series mixer-recorders. This will provide our customers with a powerful tool to capture dialogue in noisy environments."

Previously, using CEDAR with an 8-Series mixer-recorder required a separate hardware unit. This collaboration with 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.

“We had been supplying a small number of products to location sound recordists for fifteen years, but when in 2016 we released our first product designed specifically for them – the CEDAR DNS 2 dialogue noise suppressor – we found that many units were being bought for use alongside Sound Devices recorder/mixers,” said Gordon Reid, Managing Director of CEDAR Audio Ltd. “Pretty soon, customers started to ask us whether we were planning to incorporate some form of noise suppression within the recorders themselves. We hadn’t planned on this, but when we spoke to Sound Devices we found that there’s a great technical synergy between the two companies. It proved to be really simple and pleasant to work with the SD folks, and we’re genuinely excited that a specifically crafted version of CEDAR noise suppression will now be available on their recorders.” CEDAR sdnx is compatible with 8-Series mixer-recorders running firmware version 7.40 or higher.
