VIDEO : WHAT IS DOLBY ATMOS ? EVERYTHING YOU NEED TO KNOW
Dolby atmos made its debut in couple commercial movie theatres in 2012. Dolby atmos is what a surround sound should be. Dolby atmos is the surround sound you always thought you were getting but actually weren’t. At this point is good to explain the different aspects of surround sound and the difference with Dolby Atmos. The 5.1 surround sound for different environments. You get stereo channels up front on the left and the right then we add a centre channel right in the middle, then we get a surround channel on the left and a surround channel on the right, then we need a subwoofer for the base, that’s the point one part. Notice is used the word channels not speakers because channels are not speakers. I n the representation of a home theatre we have one speaker per channel but in a commercial theatre it might be needed to have eight speakers on the right and left so everyone in the audience gets to hear those surround speakers equally well. 5.1 then expanded to 7.1. It has all the same channels as 5.1 but now rear channels are added on the back wall. Once around back left and once right, and again at a home theatre, there is probably space for one speaker per channel but at a commercial theatre there may be three or four speakers on each side of the back wall. Now at a commercial theatre there us just one channel of sound for all those speakers on the left wall, one channel for all the speakers on the right wall and so on. Let’s say we have a sound that goes from right in front of you and flies off to the left and behind you then the sound will probably start in the centre speaker, move to the left front speaker and then move to the left surround speakers then move to the left surround back speakers. This way he sound seems like it went behind you to your left but in 5.1 or 7.1 when the sound moves to the left surround speaker in a theatre all the speakers play the exact same sound. Same with the left surround back. And that is how surround sound is like. Atmos is little different. First of dolby atoms adds height channels to the theatre room, now at home that might be two or four speakers. That is expressed as 5.1.2 or 5.1.4, if you have surround back speakers it could be 7.1.2 or 7.1.4. We get a top-down effect. Dolby Atmos is what is called object-based surround sound. Dolby Atmos is about a three dimensional surround sound with immerse control over where that sound is located no matter how many speakers there is. Dolby Atmos surround sound can be small or scaled up huge.

VIDEO : Binaural Mixing Explained: How to Configure Your Dolby Binaural Settings
Immersive mixing or spatial mixing is the process of mixing a track where you can place instruments or sounds in a 3D environment and so the idea is to replicate that experience when you switch over to headphones and that’s why binaural settings are super important to give the user the headphone experience that a mixer experiences in a room. Once you work on binaural mix you have to preserve the initial ideas of master mix. Don’t reinvent the mix, preserve the tonality that already has. For the binaural mix you can decide how near or far a sound should be placed. At first when you move the sound you don’t hear any binaural simulation. It can sound dry because the binaural settings are set to off This is up to the mixer to decide which elements they want to keep at the front or not of the mix on speakers without the binaural stimulation because it changes the tonality of the instrument. When you set something to near you can hear the room simulation when you pan them to the sides. When you set something to mid you can hear even more room simulation and lastly far when the height is increased you can hear even more room simulation.

VIDEO : Dolby Atmos Music Creation | New Features in Cubase 12
The set up for mixing dolby atoms is easy. You go to (PROJRCT), select “ADM Authoring for Dolby Atmos” and a window will open and then the set up is ready to run. Cubase gives some guidance to begin with so the buffer size should be 512 samples and the project sample rate should be 48kHz. Then some options from the renderer should be chosen. So the “Add Main Mix” should be selected. For the “Main Mix Channel Configuration” choose 7.1.4 and “Add Bed” channel and “Route All Tracks to Bed Channel” and with that Cubase sets up everything and is ready to mix in Dolby Atmos. Afterwards you change the Downmix to Binaural and already there is a difference compared to how the stereo mix is. From here on we can start planning my mix, I can start adding objects. You select the channels that I want to create the objects, I went at the functions and select “Create Objects from Selected Tracks” and with that Cubase has created these objects. The group of the objects and how each object is going to be mixed for binaural can be selected. The options are Off, Near, Mid, Far. The VST Multi-Paner for Dolby Atmos appears. There are two modes, the Object and the Bed Mode, and there I can start moving the object around in space. The object size, the direction of the object and the change of width happen as the objects move in space. At the render we can see the loudness and especially the integrated loudness and make sure this is within the specification. Once the mix is ready, I can export an ADM file by clicking the “Export ADM file”.
