I’ve been perfectly happy with how it sounds, though.
In your quiet room?
Once you tame the room, all sorts of options present themselves, including a relatively inexpensive microphone.
I can remember (he said in his best codger voice) when we used to recommend USB microphones without question. Now, there’s a question. Too many people are arriving with noisy vocal tracks caused by USB noise. There is no easy solution once that happens.
I can force that clip into ACX compliance, but it’s not going to be pretty. Pure Noise Reduction doesn’t work well because the whine is in the “baby screaming on a jet” range. 60dB noise floor (ACX Spec) isn’t enough, and some posters arrive with much worse problems and many of them arrive with that and other physical noisemakers.
I know you’re rolling up your sleeves right now with visions of notch filters and compression values dancing in your head. Please note that ACX has a well-used rubber rejection stamp called “Too Much Processing.”
They also have a graphic in lesson number three of their video series. I thought it worth stealing.
