That’s recording in a large empty room with wooden floors and a waterfall.
There’s no good “clean” way to suppress big room echoes, and background noise that loud is going to cause voice edge problems. The volume is right. Lots of people get that wrong.
You have the mastering order wrong (If you’re following the ACX Mastering process).
Equalization (Low Rolloff) is the rumble filter. It’s there to prevent any very low pitch sound errors from affecting anything else and goes first. It doesn’t have to be trucks going by, thunder or earthquakes. Some microphones make rumble by accident and that’s the way it is.
Then RMS Normalize to set RMS (loudness) and Limiter to clean up any tiny peaks here and there.
If you’re determined to record indoors, you might consider the Kitchen Table Studio.
That will kill room echoes and should sound a lot like your car. After that, you just have to suppress the noise (fffff). Oddly, that’s not normal noise. It does sound more like a waterfall than a gentle rain shower. That could be a data error…?
Anyway, that’s how to get rid of the echo without the filtering and gating calisthenics. Like it says in the description, after you’re done, the studio knocks apart and you can push it under your bed.
