Nu får du nye lydoplevelser på Netflix

Sennheiser AMBEO 2-Channel Spatial Audio giver en fantastisk og opslugende lyd til seerne uden et surround anlæg.

Netflix og lydspecialisten Sennheiser har annonceret en omfattende lydændring for alle seere, der har adgang til streaming (OTT) indhold med standard stereoanlæg: AMBEO 2-Channel Spatial Audio er nu tilgængelig på Netflix og giver en utrolig og medrivende lydoplevelse med almindelige stereohøjttalere. AMBEO 2-Channel Spatial Audio rendereren oversætter originale medrivende mixes til 2-kanals lyd med en rummelig oplevelse der rækker langt ud over stereo. Under udviklingen arbejdede Sennheiser sammen med Netflix og andre branchepartnere for at finjustere systemet, som nu kan fås som licens hos Sennheiser. Netflix er den første streamingplatform, der leverer denne væsentligt forbedrede oplevelse til udvalgte spiltitler.

Surveys among viewers have shown that OTT customers often access content with standard stereo equipment – be it on a mobile while traveling, when casually watching via a tablet, or because the home listening space does not allow for a full surround sound set-up. While in the past these viewers were unable to benefit from the growing amount of music and films produced in Dolby Atmos® or MPEG-H Audio, the AMBEO 2-Channel Spatial Audio feature has now changed this.

Netflix’s Stranger Things Season 4 benefits from new audio experience
AMBEO 2-Channel Spatial Audio is a two-channel rendering of an immersive mix that is a drop-in replacement for stereo. It provides an improved audio experience wherever stereo is delivered today, be it standard TV sets, stereo systems, headphones, tablets, or laptops. Netflix is the first streaming platform to deliver this significantly improved experience: On select titles, like Season 4 of Stranger Things, Netflix has made AMBEO 2-Channel Spatial Audio the default stream for any two-channel usage. Netflix viewers watching on a stereo system will automatically receive an improved and enhanced spatial experience – no user changes required.

Netflix goes the extra mile for its viewers – the OTT provider is the world’s first to offer AMBEO 2-Channel Spatial Audio to its customers. The first title to benefit from this enhanced spatial audio experience is Season 4 of Stranger Things

“Sennheiser firmly believes in the immersive future of audio,” says Dr Renato Pellegrini of Sennheiser’s AMBEO team. “Creators all over the globe have been using our tools to create outstanding immersive works, pushing the boundaries of music and film production. With AMBEO 2-Channel Spatial Audio, we are now taking the next step – making this new audio reality accessible to everyone.”

A sonic experience that is far wider than the playing device itself
Drawing on Sennheiser’s decades of research and innovation in immersive sound, AMBEO 2-Channel Spatial Audio provides immersion far beyond what two-channel speaker systems can normally deliver, but without impacting the mix or tonal balance.

According to Scott Kramer, Manager for Sound Technology at Netflix, “We feel AMBEO Spatial Audio offers a meaningful improvement for Netflix members. Re-recording mixers often tell me that it better translates their detailed immersive mix work to stereo. Crucially, this process preserves the original sound mix and respects creative intent with a remarkably clean sound.”

Respecting the original mix while giving all options for fine-tuning
“What sets Sennheiser apart from other solutions is that the AMBEO rendering respects the original mix, tonal balance and dialog integrity, which is exactly what the re-recording mixer is looking for,” explains Pellegrini. “The processing is in line with Sennheiser’s reputation to deliver tools that are ‘transparent’ and do not interfere with the original sound. In a nutshell: Sennheiser 2-Channel Spatial Audio seeks to translate mixer intent, not to overpower it.”

The rendering software runs in the streaming service’s cloud-based encoding pipelines and produces AMBEO 2-Channel Spatial Audio from existing ADM or IAB files, both industry-standard, open formats. It does not require another separate mix. A preview tool enables the re-recording mixer to compare stereo to AMBEO during postproduction and adjust the rendering settings by stems/groups. The renderer offers patented granular control of the spatialization, ranging from full AMBEO effect to standard stereo mixdown, while specific channels can be excluded from modification. For example, dialog can be preserved 100%, or modified slightly to match neighboring immersive scenes.

Total loudness is preserved, too, and a music mix can be kept for left and right channels while adding the immersive AMBEO rendering to all other channels. Naturally, all signals are properly time-aligned to match the original content.

Re-Recording Mixer Mark Paterson commented: “I’m a huge fan of AMBEO. I experimented with it a lot on the ‘Fear Street’ movies and was impressed with how the surround channel information was represented. I’m always looking for ways to get that Cinematic sound at home and on ‘The Adam Project’ I was able to make the mix sound really immersive on everything from high end soundbars to iPhones which I believe helps the audience connect more emotionally. It’s been a perfect format on ‘Stranger Things’. In the Atmos mix, Vecna’s voice wraps around you which is an important part of making him scary and larger than life. The fact that AMBEO is able to help recreate that in stereo is very impressive to me.”
