WORK IN PROGRESS
A STUDIOS MODULE · DOLBY ATMOS MASTERS · DELIVERY SHEET

Deliver the Atmos master.
No surprises from the label.

StudiOS reads the ADM without downloading it, checks it against the Apple and Dolby rules and leaves the delivery sheet next to the master. Your client hears the binaural render from the Magic Link, without knowing what an ADM is.

HOW IT WORKS

From the ADM to the delivery sheet.

The master lives in your cloud, in the song’s folder, like any other version. StudiOS reads it by ranges and checks it in your browser: the gigabytes never travel to any server.

01
It recognises it
It reads the header, the chna, the axml and the dbmd with a handful of range reads: bed, objects, frame rate, binaural modes, the tool that exported it. A 6.8 GB master is described with 7 MB.
02
It checks it
One pass over the whole file, in your browser, with checkpoints in case it drops: oversampled true peak, silences, LFE band, MD5 and SHA-256. Nineteen rules, each with its clause and its source.
03
It delivers it
The sheet as PDF for people and as JSON for the aggregator’s form, saved next to the master. The binaural and stereo renders are paired by name, and the client hears them from the Magic Link.
WHAT THE LABEL ASKS FOR

The rules, in plain words.

Apple’s immersive audio profile and Dolby’s delivery playbook, summarised. It is what StudiOS checks, and what is worth checking even if you never use StudiOS.

Integrated loudness is defined on a 5.1 render of the master. Today StudiOS reads the figure the file itself declares and says so on the sheet; its own measurement arrives with the panner. True peak, by contrast, is measured track by track and is exact.

WHAT YOUR CLIENT HEARS

The render, not the file.

No browser plays 118 channels. The Magic Link shows the master’s card and offers what can actually be heard.

The binaural, automatically
If a binaural render sits next to the master, the link plays it in its place the first time. One button switches to stereo; the whole master downloads. They pair by name, and you correct them by hand when the name misleads.
AirPods, no tricks
The page says it: on AirPods, Spatial Audio has to be off to hear the render as it is. The artist and the label hear what you heard when you approved.

The honest status: reading, checking, the sheet and binaural listening are in production, tested on real Netflix and Dolby masters of up to 6.8 GB. What is missing is measuring integrated loudness on our own 5.1 render; until then the sheet uses the figure the file declares, and says so.

The next delivery, without going back.

It is a work in progress: it will arrive as a StudiOS module, included in the plan, with nothing separate to buy. We will tell you when it opens.
