Free ADM to Eclipsa Audio converter

Convert your Dolby Atmos ADM master into Eclipsa Audio (IAMF) for free, wrap it into a YouTube-ready MP4, and publish directly to YouTube.

What you get

  • 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.
