I personally use these free software for my day-to-day work and I think these are the great software for students or anyone who don't want to spend money for some minor and simple words. These are completely free software, so you won't lose anything by trying these out.
1. Audacity - for audio editing
It's a free, open source and cross-platform software for audio editing. You can record and manipulate audio as well as it has numbers of very powerful tools. I never find a software as powerful as audacity for audio editing. Podcasters, YouTubers, and other creators are using this software to increase the quality of their audio, and it works great. Perhaps it has every single option that you need and even beyond that.
