These are just 3 of the software options you can use to edit your podcast. You can download any of the ones I have mentioned.  Please do not look at “free” as inferior. GarageBand is free on Mac and Audacity is free to download on Mac or PC. You will hear people refer to these as DAW’s Digital Audio Workstations. You can find tutorials on YouTube to get started. Do not be afraid to just dive in and mess around. I think with Adobe you get a free trial and they have videos to get you started. The great thing is once you know how to use one you will feel comfortable navigating other platforms. So if you are following this list go and download Audacity or GarageBand.
