Eclipsa Audio, live on YouTube — straight from Orbit Pro
Orbit Pro's Eclipsa Audio (IAMF) exports are now verified end-to-end on YouTube. One upload, and YouTube builds the whole family — Eclipsa, 5.1, and stereo — from your immersive master.
Immersive audio has always had a distribution problem: you can build a beautiful spatial mix, but getting it to listeners meant walled gardens and bespoke pipelines. That’s shifting — and we’ve now verified it end to end.
Eclipsa Audio exported from Orbit Pro plays back natively on YouTube. We uploaded IAMF masters straight out of Orbit Pro; YouTube accepted them, processed them, and served them as Eclipsa Audio to compatible devices — no special handling, no custom delivery.
Exported from Orbit Pro 1.5.3 Beta with the YouTube preset (IAMF only), uploaded as-is. On a compatible device it plays back as Eclipsa Audio; a desktop browser is served stereo.
One upload, every listener
Here’s the part that makes it genuinely useful: you upload the immersive master, and YouTube generates everything else from it. Our IAMF-only uploads came back with a full family of renditions:
- Eclipsa Audio — the IAMF itself, served to compatible devices
- Stereo (AAC and Opus) for everyone else
- 5.1 surround in Dolby Digital and Dolby Digital Plus — so your mix reaches living-room systems that have never heard of IAMF
The open format is the master; every legacy rendition is generated from it. And your work survives the trip — the Audio Elements (a 7.1.4 channel-based element and a first-order ambisonics scene-based element), the Mix Presentation, its layouts, and every annotation came back intact.
One thing to know before you upload
For a YouTube upload, send the IAMF on its own. A stereo “compatibility” track is worth keeping in exports you share elsewhere — it’s what lets a file play in a plain player like QuickTime — but YouTube’s ingest currently picks the stereo track when both are in the file, so your immersive mix never gets an Eclipsa rendition. YouTube builds its own stereo and 5.1 from the IAMF anyway, so upload IAMF-only and the whole family builds itself. The trade-off is per-file, so if you need stereo playback and Eclipsa on YouTube, keep two exports — one IAMF-only, one stereo-carrying. (One day we’d hope YouTube reads both the AAC and IAMF streams; today it doesn’t.)
We wrote the full walkthrough — how to check your upload, which devices play it back, and what to do if it stalls — in the docs:
