Either 100Hz rumble, or LF rolloff will suffice: you don’t have to do both.
Exactly. Low Rolloff is part of a carefully selected suite of tools. A harmonious grouping. I know it seems too simple, but it’s impressive all the things those three tools are doing for you. There are postings from people determined to get it down to one tool or step and it usually doesn’t go well.
Some USB microphones create errors down in thunder, earthquake and rumble sounds. Most times it doesn’t make any difference to the show so nobody worries about it (and it’s expensive to fix the microphone). The mastering tools do care, so Low Rolloff gets rid of rumble errors and should come first.
You have a job that doesn’t fit into the audiobook format. ACX Check needs 3/4 of a second of clean room tone to measure noise. From your description of the job, that’s the last thing they want. You can do all the mastering and measuring first, get a top quality show, and then cut it down to their format. Once you cut it down, measuring your quality is going to be much harder. I think you have to do that step blind.
If you do either of the De-Essing steps, they should come after mastering. DeEssers need stable quality and perfect volume to work right.
I’m not an editing genius. I can think of insanely complicated ways to cut the piece down to 1/10 of a second before the first word. I think I’m going to stand back and see how others would do it. Is there a specification for the end, too? Is it the same 1/10 second?
It’s further complicated by not being able to use the first ‘real life’ 1/10 of a second. That’s where your lip smacks happen. There’s a tiny one in your NewMic.wav posting, so you have to get rid of the smack first, then produce the 1/10 second. See that tiny-teensy blue thing (red dot) just left of your larger blue waves, “Select the possessive…” .
That’s a lip smack and you should cut it off before you do any other cutting. It’s almost impossible to avoid a gasp or lip smack just before your first word, so whatever we decide, I think you’re going to be doing a lot of it. I can’t believe there isn’t a shortcut or a fudge somewhere. Doing it the formal editing way is a career move…
As we go.
