Atmos Fold-Down & Stereo Derivative Mastering

Stereo versions derived from the Atmos mix, mastered properly so they stay competitive next to the immersive release.

Stereo is still the majority of streams. When a stereo version is folded down from an Atmos mix without care, the result is often quieter, phase-smeared and noticeably weaker than the immersive one.

Where fold-downs go wrong

Automatic fold-down sums objects and beds mathematically. Correlated content cancels, low end loses weight, and centre elements collapse forward. We check phase relationships across the fold and correct the mix before the stereo derivative is generated.

Mastered as its own release

Once the fold-down is clean, it gets a dedicated mastering pass — tonal balance, dynamics and loudness targeted for stereo streaming — so listeners on either version hear a finished record.

Frequently Asked Questions

What is an Atmos fold-down?

A fold-down collapses the object-based Atmos mix into a conventional stereo file, combining all spatial elements into two channels.

Why not just use the original stereo master?

You can, but the two versions will differ in balance and character. A derived and mastered fold-down keeps both releases consistent while staying competitive in loudness.

Do fold-downs lose quality?

They do when phase issues are left unaddressed. We correct correlation problems in the Atmos session first, so the stereo derivative retains full low end and centre focus.

Is mastering included?

Yes. Every stereo derivative receives its own mastering pass targeted at stereo streaming levels.
