If that code does not remove the hum you hear, your playback device could be the source.
BTW it sounds good, but here is such a thing as too much bass.
Being close to the mic can cause that, a/k/a “proximity effect”.
To cut the bass you can either back away from the mic, or use equalization to cut the bass. Audacity’s bass&treble effect will allow you to adjust bass (cut) & treble (boost) in real-time.
There are production rules not obvious when you’re starting out. The live performance should be as perfect as you can make it so you don’t have to apply a ton of effects, filters and corrections later. If you can suppress the “Announcer Voice” proximity effect by backing away slightly, you should absolutely do that. The goal is record something, do the minimum work to it, and ship it.
I have a very quiet, echo-free, well behaved bedroom. I set up a small, stand-alone sound recorder, announced a sound test, cut out the mistakes and fluffs, applied simple Audiobook Mastering, and went to make coffee.
That’s it. No filtering proximity effect, layered noise reduction, gates, sibilant filters, presence boosting or any other gymnastics.
Yep, I backed off from the mic. Sounds much better.
So, previously you had recommended that I use a de-esser. Would that fall under the sibilant filter category? Would fixing my ess problem live mean using different equipment?
I’m wondering what you mean by layered noise reduction. Would that involve doing multiple noise reductions with different noise profiles?
I am trying to make my recording setup as good as possible. I’m in a large closet full of soft things. I’m now thinking that because it is a small space that perhaps the extraneous sound I’m hearing is coming from my laptop.
Sorry for the delay in responding. For some reason I’m not getting email notifications now.
