Using Objects, especially without size metadata, may be too focused to be as effective.” “Sounds that are intentionally diffuse in the overheads, like reverb, are best placed in the overhead Bed channels, which cover the whole ceiling. In the last sentence Dolby says “try switching it to an object…” which is what I’ve done. If you have 4 speakers overhead, as I do, then routing Cinematic Rooms via a 7.1.2 bed will fold the 4 height channels to 2. If you have a concern about a source in the overhead beds, try switching it to an object so you can have more control over how it renders.”

Overheads in an x.y.4 configuration will create a phantom center of the x.y.2 component, whereas in an x.y.6 overhead configuration, it will use the point source speakers.

“Bed channels map differently to different overhead speaker configurations.

As far as I know, there is no such thing as 4-channel ceiling Bed, at least not in Nuendo, so we can achieve the same result with objects (as long as we use the right settings). This implies that Objects placed in four corners of the ceiling would be sonically identical to a 4-channel ceiling bed. For instance, an object placed in the left front with size set to zero will be identical to placing the audio in the Left channel bed.”

“Depending upon the position and size metadata applied to an object, objects and bed channels can be sonically identical.Here are two statements from Dolby’s page : have studied the Dolby documentation, and I’m not sure I come to the same conclusion that you do.
