Hanes wrote this on Gearspace, and it’s a Must Read:
“First, we need to get terminology straight. We can't use binaural and stereo interchangeably. Binaural is not stereo; it is a 2-channel downmix to be delivered to Headphones.
“So the process is to do the mix, record it into the Dolby Renderer.
“This captures the entire Atmos mix, which will be essentially a .WAV file with 12 to xxx tracks of audio. 12 Bed tracks, plus a track for each object. I'll generally use up to 20 object tracks, so that would be a .WAV file that has 32 tracks. The renderer also captures the Object metadata which tells the decoder where to pan objects.
“Then inside the renderer, there are options to create the Binaural Downmix. Basically can set each bed track and object as Off, Near, Mid, Far. This is also encoded into the ADM-BWV file that is sent out for delivery.
“At the decode end, where you are listening, your decoder will know if you are listening on Headphones and decode and dowmix to binaural with the specified settings, or know if you are listening on a multichannel speaker system where is will decode and send beds and objects to the speakers available to it. So if you have a 5.1 speaker system, the decoder will know and playback to the appropriate speakers. If you have a 9.2.6 speaker system, it will also know that and will playback.
“So one file is delivered and streamed that can be decoded to whichever listening environment is appropriate.”
