I love this kind of thing!
XSmasher4ya has made up a video showing off the sounds for the same weapons across Call of Duty: Modern Warfare 3 and Battlefield 3. Lining things up back to back really helps gain some perpective on the differences (an similarities) in approach to designing weapons sounds. (Hint: We need more of this!)
While I think it gives a good start, the locational differences of the make it tricky to fully asses. The Battlefield 3 captures are all take from the same mountain surrounded location using the “WareTapes” sound settings, which essentially increases the quieter dynamics, as opposed to Modern Warfare 3 which are captured at various outdoor locations. The extreme mountainside report slapping back seems exaggerated when used in comparison, either due to location or decreased dynamics.
Regardless, the comparison reveals a tremendous amount of time spent by both teams infusing the weapon sounds with a unique aesthetic while adding heaps of meticulous detail throughout.
Congrats to both teams and thanks for the comparison video!
Which one’s are your favorites?
