I suppose also a > little could be all right... In principle it is hard to get rid of digital distortion. With SoX I would use some naive mixing trickery like selective low-pass-filtering the distorted parts or mixing the distorted signal with a lowpass-filtered and slightly compressed version. This could mask the critical parts somewhat. You could also try a research project from the Georgia Tech University called ClipAway from 2016. I didn't try it myself, but the approach looks interesting. They have a web-site available where you can upload your file and get it "declipped". https://cplaguna-audio.github.io/ClipAway/ Maybe you can report your success (or failure)?
