Dolby Atmos Music
Dolby Atmos Music delivers an immersive audio experience that places sounds all around the listener. This guide covers how to deliver Atmos content through LabelGrid.
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
Where Listeners Experience It

Requirements
What You Need
To deliver Dolby Atmos content:
| Requirement | Details |
|---|---|
| ADM BWF file | Audio Definition Model Broadcast Wave Format |
| Bit depth | 24-bit |
| Sample rate | 48kHz or 96kHz |
| File size | Up to 2GB |
| Stereo version | Required as fallback |
File Specifications
ADM BWF Requirements:
- Dolby Atmos ADM Profile
- Proper bed and object metadata
- Trimmed to match stereo version exactly
- No extra silence at start/end
Naming Convention:
TrackTitle_DolbyAtmos.wavCreating Dolby Atmos Mixes
Production Workflow
Recording → Mixing → Atmos Mix → Rendering → Delivery ↓ Dolby Atmos Renderer ↓ ADM BWF FileRequired 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
- In track settings, find “Dolby Atmos”
- Upload the ADM BWF file
- System validates the file
-
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

- 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
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 |

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
”Do I need Atmos for every track?”
No. You can deliver Atmos for select tracks only. Tracks without Atmos files will use their stereo version.
”Can I add Atmos to existing releases?”
Yes. Update your release and upload Atmos files for the tracks you want. The release will be updated on supported platforms.
”Is Atmos worth it?”
Platforms are increasingly promoting spatial audio content. It can lead to better playlist placement and provides a premium listening experience.
”Do I need special equipment to create Atmos?”
You need the Dolby Atmos Renderer (free for music creators) and a compatible DAW. Headphone monitoring works but speaker arrays are ideal.
