Dolby Atmos mixing and mastering

Stereo places your music between two speakers: left and right. Dolby Atmos breaks that boundary and spreads the sound into a three-dimensional space around the listener — including height — so each element can have its own position in the sound field. The vocal up front, the backing vocals opening to the sides, the percussion wrapping around, the ambience closing in overhead. It's the same song, told in a much bigger space.

At Stitos we offer Dolby Atmos mixing and mastering 100% online, delivering the spatial master ready to distribute on Apple Music, Tidal and the rest of compatible platforms. It's a premium service, made for releases where the immersive experience adds something real.

What Dolby Atmos spatial audio is

Dolby Atmos is an immersive audio format based on objects. In a traditional stereo mix, each sound is placed at a fixed point between two channels. In Atmos, each element is an object placed and moved freely in a 3D space, and the listener's playback system — headphones, a soundbar, a home cinema setup — translates that information into whatever it has available.

The result is a sense of width, depth and separation that stereo can't deliver. On headphones it's reproduced via binaural, so anyone with AirPods on Apple Music can hear the spatial version without special equipment. That's why platforms like Apple Music give their own visibility to tracks in Atmos.

What the service includes

• Spatial mix. From your stems, we place each element in the three-dimensional field with musical intent: what goes up front, what wraps around, what gains height. It's not "spreading" the sound, it's designing the song's space.
• Atmos master. Level and balance adjustment within the loudness specs the format requires (Atmos targets differ from stereo), making sure the translation to binaural and to speaker systems sounds coherent.
• Consistency with the stereo. We make sure the Atmos version respects the character of the track and doesn't contradict the stereo version you already distribute.
• Delivery ready to distribute. The ADM BWF file platforms require, plus a binaural and a stereo reference. We coordinate the exact format with your distributor.

When it makes sense

Dolby Atmos is an extra, not a requirement. The stereo version remains the main format of your release. Atmos adds value when:

• You want to take advantage of the visibility Apple Music gives to spatial-audio tracks.
• The track has a rich arrangement — layers, ambiences, backing vocals, detailed production — that benefits from the extra space.
• It's an important release where the immersive experience reinforces the project's positioning.
• You're after a premium finish that sets your music apart from the majority, which still stays in stereo.

If your priority is to have a solid stereo first — and for most projects that's the right starting point — begin with professional mixing and online mastering. Atmos can be added afterwards on that same material.

How the service works

1. We talk about the project. You tell us the song, where it stands (stems, finished stereo mix) and which platforms you want it for. We assess whether Atmos adds value and give you a timeline and quote.
2. You send the material. The stems or tracks, with the same export guidelines as a normal mix. We guide you so everything arrives clean.
3. We produce in Atmos. We mix and master the spatial version, taking care of the translation to binaural and to speakers.
4. We review. You listen to the binaural version and tell us what to fine-tune.
5. We deliver. You receive the ADM BWF and the references, ready to upload to your distributor.
