I have taken an important interview with my laptop and now found out in retrospect that unfortunately I'm not understandable by between. Is there the possibility to make my voice audible? Unfortunately the interview can't be repeated.
Only what is recorded can be made audible. This is possible with a video editing program or Audacity, if the soundtrack can be edited separately.
Possible solutions, if not:
Show questions as text in the video
to postpone the questions later and to add them to the original recording.
Video or just audio?
Only audio
Then you can try Wavelab or Audacity to raise the level where you are too quiet. Of course, this is only possible if you are even heard. So louder you can do it already, but as has already been said, such a software can only amplify what is available.
Load a short sequence with something quiet and something normal somewhere high, then you might be able to guess if it makes sense to keep trying.
