Typically, these surround sound systems boiled down to:
three speakers in front (Left, Center, Right) plus
either two or four "surround" channels to your sides and/or behind you, plus
the Low Frequency Effects (LFE) channel used by sound designers when they wanted to shake you up, as with explosions or threatening, deep bass in the musical score
Of course, mixing with these extra channels beyond simple stereo is a bit more complicated. But the principle is the same: if you want something to appear between two presumed speaker locations, you put some of that particular sound into both of those adjacent speakers… just like Frank.
INTRODUCING IMMERSIVE AUDIO “OBJECTS”
The answer: what if we take an entirely new approach that takes advantage of the incredible processing power we have today in computers and DSP chips?
All channel-based systems assume a specific arrangement of speakers and then leave it to the mixer to figure out which ones should be used to make a sound “appear” in a certain place. What if we change the approach?
How about attaching a simple description to each sound, describing where it is at any moment in time? This “metadata” (which simply means “data about other data”) could be updated regularly, perhaps in every frame of a movie, for example.
By changing the location metadata over time, we can make objects move. If we include all three dimensions (length, width, and height locations), we could make any sound or collection of sounds move around in the room in any way we wished.
Both Dolby Atmos and DTS:X Pro use metadata to describe sounds’ locations within the room.
CONCLUSION
We are all staying at home more these days. Do you feel the need to escape once in a while? While nothing will replace being able to get together with friends and family again, having an immersive sound system in your home can be the Great Escape you need in the here and now. It will also be a fantastic thing to share with your friends and family when that time comes around once again.
