Split stems and separate reverb. Atmos placement is handled automatically for an immersive result.

Export and Deliver

Export an ADM BW64 file you can open for final checks and send through your streaming delivery workflow.

Simple Process, Big Results

Upload a stereo track and let automatic processing do the heavy lifting.

Split stems, isolate reverb, isolate the kick. Click Export, and Atmos placement is mapped automatically. No manual channel routing is required.

Restore for Best Audio Quality

Restoring audio before conversion helps recover clarity and detail lost in compressed sources. This example uses AudioSR with a 4kHz cutoff in mono.

OriginalNeural Analog

Reuse the existing reverb

Isolate the reverb tail. It's automatically mapped ambience in 3D space for depth without mud.

Example from Remove Reverb: isolate the reverb tail

Compare the original reverb-heavy vocal with the dry stem, then switch to Reverb only. This clean separation enables spacious, controlled 3D placement.

Frequently Asked Questions

What is Dolby Atmos?

Dolby Atmos is an immersive audio format that places sounds in 3D space instead of only left and right stereo. This adds width, depth, and height so a mix feels bigger and more detailed.

Use Convert to Dolby Atmos when you want a stem-based Atmos-style export from an existing track.

What is ADM BW64?

ADM BW64 is the main exchange format for Dolby Atmos projects. It stores both the audio and the metadata needed for immersive playback, so sessions move cleanly between tools and delivery steps.

The Atmos conversion workflow exports an ADM BW64 file after stem routing and loudness preparation.

Do I need to map stems to Atmos channels manually?

No. Mapping is automatic. Stems and reverb layers are detected, then routed to appropriate Atmos positions without manual channel assignment.

You still control the source quality: cleaner stems from stem splitting usually produce a cleaner Atmos export.

Should audio be restored before Atmos conversion?

Yes, when the source is compressed or artifacted. Restoring first can recover clarity and high-end detail, giving cleaner stems and better spatial results in the final Atmos upmix.

Run Audio Restoration before Atmos conversion if the source is an MP3, AI-generated track, or old recording.

Why do binaural tags matter in Atmos?

Binaural tags control how Atmos elements translate on headphones, so listeners on headphones can still hear a clear immersive image. Good tagging keeps vocals focused while ambience and reverb feel wider.

The Atmos conversion tool applies mastering-friendly defaults so the exported file is useful for further delivery work.

Will Atmos conversion keep my mix faithful to the original?

The goal is to preserve artistic intent while opening the mix in 3D. Stem-first processing and vocal-focused routing help keep lead vocals stable, protect punch, and avoid washed-out results.

Use Convert to Dolby Atmos when you want an automated stem-based Atmos export rather than a generic stereo widener.

How is this different from other upmixing services?

Most upmixing services do not split stems. They mainly add reverb and widen the stereo image, which can make a mix sound muddy and reduce punch.

This workflow first splits stems, separates reverb, then automatically places each part in the right Atmos space. The result is cleaner, more defined, and more faithful to the original artistic intent.

Delivery stays aligned with Dolby Atmos standards through ADM BW64 export, binaural tags, and mastering-friendly defaults.

Specialized vocal-fidelity pipelines help keep lead vocals clear and stable instead of washed out.

Many alternatives are built for audio professionals and come with complex setup. This process stays simple: upload, process, export.
