How often will this question pop up on the forum lol. Idk what you want to do, but Reaper, audacity, and Goldwave are your 3 accessible options - Reaper being the most robust, depending on how much you know about audio is how easy or hard a time you'll have learning Reaper, but it's worth it. I used to use audacity, works pretty well if you want something free to get your feet wet with, but like I said, not sure exactly what you want to do.
I have a computer that still has windows movie maker, so I just put a still image or stock footage that loops seamlessly in there and copy paste it throughout the video until it's done. My videos are short, I do music covers, so not sure how that will work for what you want to do but it's an option for making videos without having to edit sniz. Reaper also has where you can sync video with audio as well, but once again it's a matter of how much you want to learn using reaper.
So really, it's up to you. Those are the three best options for blindies to use for audio imo, hope that helps!
