I take a look at a new way to balance channels in a Dolby Atmos system, all using averages. I've found that using SPL to balance your channels gets things close, but SPL is very random. I wanted to find a way to absolutely know channel levels. You can see when taking subwoofer measurements that the measurement is all over the place. Using lots of averages means you find the exact volume levels for all speakers. I did this using REW and the Spears & Munsil Ultra HD Benchmark (2023) on 4K Ultra HD Blu-ray. The balance in my system is now incredible using this method; please check it out. This can also be achieved using the Spatial Audio Calibration Toolkit (by Techno-Dad and Joe N Tell).
NOTE: One thing I forgot to discuss is that when taking a subwoofer measurement, you should change the calibration file from a 0 degree file to a 90 degree file. Subwoofer volume is best measured with the microphone pointing straight up. However, for all of my other speakers, I used a 0 degree calibration file, as I have found it to be more consistent and accurate than a 90 degree measurement.
