Free ADM to Eclipsa Audio converter

  • Converts an ADM master (WAV or BWF) from a Dolby Atmos workflow into Eclipsa Audio (IAMF). No remix, DAW, plugin or command line needed.
  • Rebuilds the mix as a 16-channel third-order Ambisonics sound field instead of folding objects into a fixed speaker layout, so sounds stay sharp and correctly placed on headphones and speakers.
  • Reports an Intent Fidelity Score (patent pending) that measures how faithfully the Eclipsa Audio scene keeps the spatial intent of the original master.
  • Keeps the source PCM audio without unnecessary lossy re-encoding. Downloads as .iamf or muxed .mp4, or publishes directly to YouTube.
  • Free, with no watermark. A free Spatial9 account is required.

Frequently asked questions

Can I start with a finished song or video?

Yes. Bring a completed stereo song or a finished video and Spatial9 produces an immersive version from it. Original stems help but are not required.

Do I need stems or audio engineering experience?

No. If you have stems you can supply them, but Spatial9 can separate an existing mix. You do not need to operate a mixer or position sources yourself.

What files will I receive?

Supported deliverables depend on your plan and include immersive export formats such as ADM, Eclipsa Audio, binaural, and Ambisonics. See the pricing page for exact formats per plan.

How do Music and Video workflows differ?

Music is available now. Video production is in early access—you can request an invite and we will bring you on as it opens up.

Can I automate a catalog or integrate Spatial9?

Yes. Teams can submit in batches, track job status, and integrate through our API and webhooks. Talk to us about production at scale.

What is included in the free ADM-to-Eclipsa converter?

You can convert an ADM master (WAV or BWF) to Eclipsa Audio at no cost and with no watermark. A free account is required.
