See the mix move
Objects travel through the room and pulse with their level; the 7.1.2 bed speakers light up as they play. Orbit around it to look from any seat.
For Dolby Atmos mixes
Review Dolby Atmos mixesin 3D, in the browser
Upload the ADM BWF master and your client sees the room: objects moving, the bed speakers lighting up, the picture on the wall. Notes pin to the exact sound — and follow it.
Spatial sound plays in Safari only for now — other browsers play stereo.

The 3D view · beta
An Atmos master, as a room
A stereo waveform can’t show where a sound is. The 3D view can — so the notes can say which sound they mean.
Notes on a sound, not just a second
Pin a comment to an object or a bed speaker. Click the comment later and the pin rides on that object as it moves.
The picture in the room
Link an MP4 from the same folder and it plays on the room’s screen. Set the sync from the playhead or type an offset in 0.04 s steps.
Your client sees the same room
Share a review link as usual: the 3D view, the linked picture and your sync settings come with it, and clients can pin notes too.
Two kinds of Atmos
The master, and the streaming file
Pibox handles both. The master opens in the 3D view; an Atmos track inside an MP4 plays wherever the browser can decode it.

- Plays as a stereo fold-down in every browser for now, Safari included.
- On the Pro plan and above; other plans hear the stereo downmix.

Walk an artist or label through the object moves without a room booking — and get notes on the guitar that drifts, not “something around 2:10”.
Post-production for film and TV
Picture on the wall, sound in the room: supervisors and directors comment on the helicopter, the crowd, the score — each pinned where it lives.

Questions about Atmos in Pibox
Does the master play in Dolby Atmos in the browser?
Not yet. In the browser an ADM BWF master plays as a simple stereo fold-down, while the 3D view shows where every object is. If the linked MP4 carries an Atmos (DD+ JOC) mix, Safari can play that track through Apple Spatial Audio instead — switch on Play picture audio.
Which browsers play Atmos spatially?
Only Safari, for now. Safari plays an Atmos track in MP4 through Apple’s Spatial Audio engine, so you hear it spatially on AirPods or another spatial-audio device. Chrome and Firefox can’t decode Atmos and play a stereo version; TrueHD Atmos plays as stereo everywhere. Hover over the Dolby Atmos badge under the player to see what is playing.
Which plans include the 3D view?
The 3D view is on the Pro plan and above. On other plans, Atmos masters play as a stereo downmix.
Do my clients need special software or speakers?
No. They open the review link in a browser — no account and nothing to install — and see the same 3D view, picture and sync you set. For spatial listening of an Atmos MP4, Safari with AirPods or another spatial-audio device works.
How do I export the master?
As an ADM BWF (.wav), either from Pro Tools (File → Bounce Mix) or from the Dolby Atmos Renderer. Upload it next to the picture MP4 and open it once processing is done; large masters take longer.
Is the 3D view finished?
It is in beta: it works today and keeps improving. Tell us what you need from it — we read every note.
