Hello Mario,
I have used "Camtasia Studio" in the past for a little bit of video / audio recording. This is not free but it has a lot of high end features. I can recommend "OBS Studio" which is very popular and then also "Debut Video Capture". Both are free.

As suggested by others, Reaper can do the audio polish if needed and Camtasia allows inserting of audio to synch with video. If I can help with anything just PM me. I have some time these days. Dan
