How to Decode an Atmos File to get the stems
- Get Dolby Reference Player for windows and install it trought the .msi file
- Launch "CMD" and paste this command :
cd "C:\Program Files\Dolby\Dolby Reference Player"
- Then paste this next command :
gst-launch-1.0 --gst-plugin-path="C:\Program Files\Dolby\Dolby Reference Player\gst-plugins" ^ filesrc location="Your\\Original\\AtmosFile\\Path.m4a" ! ^ qtdemux ! ^ dlbac3parse ! ^ dlbac3dec drop-delay=true drc-mode=rf out-ch-config=21 ! ^ dlboar drop-delay=true out-ch-config=20 ! ^ wavenc ! ^ filesink location="Wanted\\Path\\ToYour\\Output\\MusicFile.wav"
- Normaly you should recieve a .wav file at the output path you choosed
- Then open your DAW such as Audacity and place it your new .wav file. Normaly you should see multiple tracks, these are the splitted stems of your original Atmos file !
