Dolby Atmos and Hi-Res Audio

Updated July 2026.

Yes — LabelGrid delivers Dolby Atmos spatial audio and high-resolution masters on every plan, at no extra charge. Dolby Atmos places sounds all around the listener for an immersive experience, while hi-res and lossless tiers preserve full studio quality. This guide covers how to prepare and deliver both through LabelGrid.

For the marketing overview, see Dolby Atmos and Hi-Res Audio on labelgrid.com.

What is Dolby Atmos Music?

The Experience

Unlike traditional stereo (2 channels) or surround sound (5.1/7.1 channels), Dolby Atmos uses:

Object-based audio - Individual sounds positioned in 3D space
Height channels - Sound from above, not just around
Adaptive playback - Automatically adjusts to listener’s system

Creating Dolby Atmos Mixes

Production Workflow

Recording → Mixing → Atmos Mix → Rendering → Delivery
                         ↓
              Dolby Atmos Renderer
                         ↓
                    ADM BWF File

Required Tools

Tool	Purpose
Dolby Atmos Renderer	Create Atmos mixes
Compatible DAW	Pro Tools, Logic Pro, Nuendo, etc.
Monitoring	Atmos-capable speakers or binaural

Mix Considerations

Start with a great stereo mix
Think in 3D space
Don’t over-pan objects
Check binaural translation
A/B with stereo frequently

Uploading Atmos Content

Step-by-Step Process

Prepare your files
- Stereo master (required)
- ADM BWF Atmos file (for Atmos tracks)
- Same duration and timing
Upload stereo first
- Add your track normally
- Upload the stereo WAV/FLAC
Add Atmos file
- Open the track editor and click the Dolby tab
- Enter the ISRC for the Atmos version (a separate ISRC from the stereo version)
- Use the Click to upload or drag and drop area to upload your ADM BWF file
- The system validates the file as it uploads
Verify alignment
- Atmos and stereo must match exactly
- Same start/end points
- Same track structure

Validation Checks

The system verifies:

✓ Valid ADM BWF format
✓ Correct metadata structure
✓ Duration matches stereo
✓ Proper sample rate
✓ No clipping or errors

Platform Delivery

Where Atmos Delivers

Platform	Atmos Support	Notes
Apple Music	✓	Labeled as “Spatial Audio”
Amazon Music	✓	Requires HD subscription
TIDAL	✓	Masters tier
Other platforms	Stereo only	Receive stereo version

What Listeners See

On supported platforms:

“Dolby Atmos” badge
“Spatial Audio” indicator (Apple)
Special playback icon

Fallback Behavior

When Atmos isn’t supported:

Stereo version plays automatically
No listener action needed
Seamless experience

Quality Guidelines

Best Practices

Do:

Create intentional spatial placement
Use height for atmosphere and effects
Maintain strong center/front presence
Test on multiple systems
Check binaural rendering

Don’t:

Put lead vocals in extreme positions
Over-use panning gimmicks
Ignore the stereo fold-down
Rush the Atmos mix
Submit poorly rendered files

Prohibited Practices

The following will result in immediate rejection:

Stereo upmixing — Automatic or algorithmic upmixing from stereo or mono sources
Source separation — Extracting stems from stereo to create an immersive mix
Stereo in Atmos container — Placing stereo audio in a Dolby Atmos container format
Missing elements — Vocals or instruments missing compared to the stereo version
Version mismatch — Different duration, added elements, or a different recording versus stereo
LFE abuse — Full-frequency content in the LFE channel (low-pass filter required)

Common Issues

Issue	Solution
Vocals sound distant	Keep vocals in center/front
Mix sounds empty	Balance objects with beds
Too much movement	Subtle positioning is often better
Binaural sounds wrong	Check renderer settings

Technical Specifications

ADM BWF Structure

ADM BWF File
├── Audio Essence (PCM data)
├── ADM Metadata (XML)
│   ├── Programme
│   ├── Content
│   ├── Objects
│   └── Packs/Channels
└── Chunk metadata

Sync Requirements

Requirement	Specification
Sync tolerance	Atmos and stereo versions must differ by 50 milliseconds or less
Content match	Atmos version must match the stereo version in content, arrangement, and mix elements
Audio sources per track	Only two allowed (one stereo, one immersive)

ISRC Requirements

Each Dolby Atmos track requires a unique secondary ISRC separate from the stereo version.

Troubleshooting

Upload Errors

“Invalid ADM BWF format”

Check file was exported correctly from renderer
Verify ADM metadata is present
Re-export from Dolby Atmos Renderer

“Duration mismatch”

Atmos and stereo must be exact same length
Trim to match precisely
Check for extra silence

“File too large”

Maximum 2GB per file
Consider lower sample rate (48kHz)
Check for unnecessary data

Playback Issues

Not showing as Atmos on platform:

Allow 24-48 hours for processing
Verify platform supports Atmos
Check delivery status in LabelGrid

Sounds wrong on playback:

Test on multiple devices
Check binaural rendering
Verify mix in Dolby tools

FAQ

”Does LabelGrid support Dolby Atmos and hi-res audio?”

Yes — LabelGrid delivers Dolby Atmos spatial-audio mixes and high-resolution masters on every plan, at no extra charge. Deliver an ADM BWF Atmos file (24-bit LPCM, 48 kHz) with its own ISRC alongside your stereo master, and upload the highest-quality source you have for lossless and hi-res tiers.

”Which platforms support Dolby Atmos?”

Apple Music (labeled Spatial Audio), Amazon Music (with an HD/Ultra HD subscription), and TIDAL support Dolby Atmos. Platforms that do not support Atmos automatically play the stereo version, so listeners always get a working playback.

”What file format does a Dolby Atmos mix need?”

An ADM BWF (Audio Definition Model Broadcast Wave Format) file at 24-bit LPCM, 48 kHz, conforming to the Dolby Atmos Master ADM profile. It must be created from stems or multitracks — not upmixed from stereo — and delivered with a matching stereo fallback.

”Do I need a separate ISRC for the Dolby Atmos version?”

Yes. Each Dolby Atmos track requires its own ISRC, separate from the stereo version. Enter it in the track editor’s Dolby tab when you upload the ADM BWF file.

”Does Dolby Atmos delivery cost extra?”

No. Dolby Atmos and hi-res delivery are included on all LabelGrid plans with no upcharge — you only need the Atmos file and its ISRC.
