So, on one section of an audio file, I have a 15db 140hz boost, and and in the next, I have a 12db 140hz boost. How would I smoothly transition these without it sounding odd, and suddenly changing. This is simply an example scenario, so telling me how to do this between other transitions as well would really help. Thanks.
Note: So, this is my first question in the sound stack exchange, and I'm not all that great with music production. The most musical talent I have is playing french horn and trumpet, and noobishness should be expected.
