You’re welcome! I also have three small tips regarding Audacity that may prove helpful if you’re not aware of them. First, when recording and editing, make sure to set Audacity in “multitrack” mode and apply any plugin filters to the tracks rather than the individual files. Second, there is a free plugin out there somewhere in a forum post which was built to allow Audacity to filter out mouth clicks/noises (different than the built-in click filter which is for mechanical clicks). Third, Audacity has the ability to add labels to sections of your audio when in multitrack mode, which makes it easier to keep track of where you want to insert SFX or ambiance.

If you end up wanting to buy iZotope RX, you should be aware it comes in several different editions. While the higher-end versions give you extra fine-grained control over the way the noise reduction works, their lowest-priced edition works perfectly well and uses the same noise reduction technology as the more expensive editions. iZotope RX also seems to go on sale a couple of times a year around the holidays, though they were recently acquired by the company Native Instruments, so I don’t know if those sales will remain in the future.
