Q: My voice on record is louder than the voice of the person I'm talking to. (or vice versa)
A: Skype uses automatic volume adjustment if your microphone volume level is too loud/quiet. The recorder saves the actual volume level (before Skype level adjustment). You can try to change the volume level for microphone in Windows control panel. Go to Control panel -> Sound and Audio devices -> Volume.
e.g. if your voice on the recording is louder then the voice of the person you're talking to, then try to reduce the microfone volume in Windows settings.
