Spatial mixes that survive real rooms
Dolby Atmos Music Mixing & Sonos Playback Checking
Dolby Atmos music mixing and mastering for artists who want a spatial release that translates from headphones to Sonos Era 300, Arc, Beam Gen 2, and real living rooms.
Dolby Atmos Music is not "Sonos recording". Sonos is one of the playback environments listeners use after the release is live. The work happens in the mix and master: deciding what stays anchored, what moves into the height field, how vocals hold focus, how low end stays solid, and how the stereo master and spatial version feel like the same record. We help artists create an Atmos version that adds space and depth without turning the song into a demo of effects.
A good Atmos music mix starts with arrangement judgment. Some parts belong in the front image because they carry the song. Other parts can wrap around the listener, sit above the bed, or become objects that create movement and scale. We explain 7.1.4 bed and object thinking in plain English, then make choices that fit the track. Drums, bass, lead vocal, and key hooks need weight and clarity; ambience, backing vocals, percussion, synths, guitars, strings, and ear-candy can often open into the room. The aim is immersion that still feels musical on a normal play-through.
Playback translation is the niche most artists miss. A spatial mix may feel huge on headphones but collapse on a soundbar, or feel exciting on Sonos but lose the vocal fold-down. We check the mix through binaural headphone rendering, stereo fold-down, and real consumer playback thinking, with Sonos Era 300, Sonos Arc, Arc Ultra, Beam Gen 2, and Sonos Ace named in the brief where they matter to the listener. That does not mean every Sonos device plays the same Atmos stream in the same way. It means the mix is built with actual listener behaviour in mind, not only the ideal studio render.
Delivery depends on the release path. For many independent artists, the practical goal is a stereo master plus a spatial mix prepared for Apple Music Spatial Audio and Dolby Atmos Music delivery through the chosen distributor. For label, sync, or post clients, deliverables may include stems, reference exports, print notes, and a format-specific handoff pack. ADM/BWF can be discussed at booking if your distributor asks for it; we confirm format support before taking on that deliverable so the scope stays honest.
This service works locally in Brisbane or remotely. You can bring a finished stereo mix, stems from another mixer, or a project we have already mixed and mastered at Animus. If the production was built with spatial in mind, we can create a deeper Atmos version. If it was not, we can still make smart choices from the available stems and advise where new elements, backing vocals, pads, returns, or effects prints would help the spatial version feel intentional.

How It Works
- 01
Scope the release
We review the stereo mix, stems, release plan, distributor requirements, and references. This step decides whether we are building a spatial companion mix, a deeper reinterpretation, or a careful Atmos version that stays close to the stereo master.
- 02
Build the spatial mix
We place the song into a 7.1.4 and object-based working field, protecting the vocal, drums, bass, and hooks while opening supporting elements into width, height, and depth. Movement is used only where it helps the record.
- 03
Check translation
We compare the Atmos render against the stereo master, then check binaural playback, stereo fold-down, and consumer listening targets such as Sonos soundbars, Era speakers, and headphones as part of the notes process.
- 04
Revise and deliver
We revise against your notes, confirm the release path, and deliver the agreed files. If a distributor requests ADM/BWF or other format-specific material, we confirm support and scope before final delivery.
Where It Fits
FAQ
Dolby Atmos Mixing FAQs
Is Sonos Atmos recording the right term?+
No. Sonos is a playback system, not the recording format. The right service is Dolby Atmos music mixing and mastering, with Sonos playback checking. That means we create a spatial mix for Dolby Atmos Music and Apple Music Spatial Audio, then think about how it will feel when a listener plays it through Sonos Era 300, Arc, Arc Ultra, Beam Gen 2, Sonos Ace, headphones, or a stereo fold-down. The creative work is still mix work: placement, balance, depth, low-end control, vocal focus, and translation.
Do I need a separate Atmos mix if I already have a stereo master?+
Yes. A stereo master cannot simply be converted into a meaningful Atmos release. Automated upmixing can make sound appear wider, but it does not make musical decisions. A real Atmos mix uses stems or a full session so the vocal, drums, bass, effects, backing parts, and ambience can be placed intentionally. The stereo master remains the main reference so the spatial version feels like the same release, but the Atmos version is a separate mix with its own balance and checks.
Will my Atmos mix play on Sonos?+
Dolby Atmos playback on Sonos depends on the device, source, app, subscription, network, and whether the release platform serves an Atmos stream to that device. Sonos Era 300, Arc, Arc Ultra, Beam Gen 2, and some headphone paths can be part of a spatial listening setup, but they do not all behave the same way. We cannot control what a streaming platform or device app chooses to serve, but we can build and check the mix with those real listening paths in mind so the release is not only judged on studio headphones.
Can you make an Atmos mix remotely from my stems?+
Yes. Remote Atmos mixing works well when stems are clean, labelled, and exported from the same start point. We send a stem export guide, check the files before starting, then build the spatial mix at Animus and send listening references and revision notes online. If your stems are too limited, we will say so early and suggest fixes, such as printing effects returns, separating backing vocals, exporting percussion layers, or adding a few spatial ear-candy elements before the final mix starts.
What should I send for Dolby Atmos mixing?+
Send the approved stereo mix, stereo master if it exists, a reference list, the tempo and sample rate, and full-length WAV stems from the same start point. Keep the lead vocal, backing vocals, drums, bass, music groups, effects returns, and special moments separated where possible. Do not only send a two-track stereo file unless the brief is a technical consultation or a very limited spatial treatment. Better separation gives better placement choices and a cleaner fold-down.
What deliverables do I get?+
Deliverables are scoped before the job starts. A typical independent music project may include the final stereo master, spatial reference files, fold-down checks, notes, and files prepared for the distributor workflow you are using. Label or platform-specific delivery may ask for stems, metadata, print notes, or ADM/BWF-style material. We confirm those requirements before accepting them because distributor specs vary and it is better to be precise than promise a format that is not needed or not supported for your release path.
