Adobe is getting into podcasting (looks like they are taking on Descript), and as part of their pre-launch, they are offering free tools. I don’t know how long they will remain free but use it while it is free.
Check your mic for free will give you advice on your mic settings. I like how it lets me hear how I actually sound, and I’ve actually thrown away a headset because I didn’t realise how terrible it sounded on Zoom calls.
The Enhance Speech tool is supposed to fix background noise and reverb. I can’t say how good it is for your use-case, but hey, it’s FREE (for now), so use it while you can if you don’t have a better option.
Go, go, go.
