Sennheiser presents AMBEO 2-Channel to live broadcast applications in NAB 2023

Sennheiser has announced launches of AMBEO 2-Channel Spatial Audio to live broadcast applications. At the NAB show, Sennheiser Pro Labs will demonstrate a prototype of the AMBEO 2-Channel Spatial Audio live renderer – ready for immediate field testing with broadcast partners at booth No. C5217.

The technology unlocks investments into surround and immersive content for all viewers by translating immersive mixes into an enhanced 2-channel experience that works on any stereo device.

The first implementation of the AMBEO 2-Channel Spatial Audio live renderer is running on Merging Technologies’ powerful AES67 devices, used in many broadcast environments.

The live renderer transforms, in real time, standard multichannel surround and immersive formats into two channels of audio that can be delivered anywhere stereo is delivered today. Patented controls, adapted for use in a broadcast environment, allow for finetuning of spatialization settings to maintain mix integrity and dialog intelligibility.

​Renato Pellegrini, Head of Pro Labs, Sennheiser: “Today’s large, televised sporting events are increasingly produced in immersive formats. However, both distribution pipelines and viewer access to immersive speaker systems have limited its reach into homes – leading to a duplication of efforts between stereo and immersive mixes. Now, using our renderer, broadcasters can instead focus on immersive formats and know they can reliably translate those mixes into a far better stereo experience than could be previously achieved.”

Pellegrini continues, “Live broadcasting presents special challenges, and productions must operate with tight precision and coordination. The sound mix must be ready within a few video frames, tools must fit within specific workflows, and gear must be dependable day-in, day-out. When we set out to build the live renderer, this environment was front of mind.”
