@Cyril Blanc I think language may be getting in the way again. Reading @Dietz’s reply’s and your posts there seems to be a lot of cross purpose.

I see. Well, that's neither the way actual 3D recordings of any kind are made (be it 9.x.4 or any other format), nor the way MIR 3D works. If that's what you expect, then you should really think about selling your MIR 3D licence and read up on modern recording techniques.

Hi @Dietz

I am lost, I am a beginner, can you explain what I should do to provide a Dolby Atmos recording to be sold on Apple Music

Gents The discussion is interesting but I was trying to avoid MIR here and discuss the use of the Synchron player mics for Dolby Atmos a valid topic as it even has a dedicated video.

Gents keep cool. Dietz has mentioned many times in different threads that a Synchron instrument is not meant to be used in MIR. This is regretful but I fully understand that the close mics signals of the SY Stage A recordings are not dry enough as a source for MIR. So therefore I opened my separate topic purely dedicated to the full Synchron Libraries microphone use in particular for Dolby Atmos.

Dietz maybe you can clarify the relative microphone heights which should be entered in the Atmos objects. Firstly, am I correct that the SY decca tree and surround mics were at about 3 m above the stage and secondly do you have info on how high the "High" and High Sur" mics were mounted during the recording?

A last point on microphone positions; on the overview page of the libraries, the SY Brass and WW show a different, wider, surround microphone setup than the SY strings and percussion libraries. I am not sure why as especially the percussion instrument positioning covers the whole width of the SY Stage. Do all sketches on the library overview pages reflect the actual recording position or is there an issue with the sketches?

It is possible to set up the Atmos object consistent with the real microphone positions. So if these libraries would indeed have a different surround widths dependent on the instrument group that is easy to enter in the 3D panner.

This is a question for @air Bernd Mazagg of Vienna Synchron Stage. 😊

Thanks Dietz, Paul can probably also answer these questions as he presented the SY Player Atmos video made with Bernd’s input but I would be very happy with some input.

I think it all goes back to the question if you in Dolby Atmos you have to closely simulate the real venue where the samples were recorded or you just use approximate positions in a more or less standardized (L/H/W) listening environment represented by the room graph with the object positions in the DAW or Dolby panner

@Cyril Blanc - Moderate your tone and stay polite, please. So many people are trying to help you out with your confusion - you have no reason to complain.

@Cyril Blanc Please enjoy the rest of the weekend and use the time to calm down.
