Manual BRZ sounds different than automatic one.

You are a man of interesting taste. Boxer with spun rod bearing matched with an auto is something I wouldnt even send to subaru nightmare museum.

If not that, then I'd suspect it has something to do with the fuel flow as controlled by the computer. I drive long distances and use the cruise control quite often. I have noticed that the engine tone sometimes changes when I engage or disengage the cruise, even at the same speed and RPM. When the computer takes over, the engine gets quieter.

With the automatic, the computer is always in control. Since the manual is putting more of the decisions in the driver's hands than the automatic, perhaps the computer allows more fuel to flow for the manual to be ready for the driver's inputs, whereas the automatic's computer can reduce the fuel flow since the shift points will be more predictable. With different fuel flow, you'd get a different sound.

I own a 2015 Automatic FRS and I can confirm this is true when I start driving in the morning I have it in drive but when i switch it to manual mode even at 2k rpm or whatever rpm it was at while in drive the sound changes

A manual trans vehicle will always sound different that the auto trans equivalent because the resonance of the mechanical coupling (clutch) vs. the fluid coupling (torque converter) skews the audio note. Even a "lock up" torque converter skews the audio resonance due to the damping effect of the extra mass of the fluid.
