I love sound engineering and design as a whole. Music production was what got me into it. It’s still mind boggling to me how much you can do with a simple sine wave and process it into essentially unlimited amounts of various sounds.
I never knew a thing about music theory, synthesizers, drum machines, etc. Almost 7 years down this path and I’m still learning as I go and just as curious as when I first started.
Seeing different instruments through an oscilloscope or watching the different frequencies dance as a whole on an EQ plugin is my favorite.
