As part of my Hero System episode, I am trying out Adobe Audition, which has several tools to clean up the audio automatically, rather than my (inexperienced) adjustments. It also should allow for much cleaner edits and merging of the various files. I know the typical recommendation is Audacity, which is a free option, but I am also considering changing video editing to Adobe Premier Pro instead of Davinci Recode, so this is all part of the same experiment. So far, not really noticing much of a difference, but then my skill level is very basic. I have applied the auto-filters, which certainly helps, but I am not sure if it is a big enough improvement to justify the cost and relearning.
