Bumping this. To drum up interest I will say if you do hear a male voice it's my dad cucking me ._.

I know nothing about anything but I turned up the volume up by 36db in audacity and all I can semi-confidently say I heard was "I'm"

I hope someone smarter than me finds this thread.

From what I can hear, after stripping away the high frequencies (nighttime insects I think?) and the low frequency knocks (either footsteps on wood or knocking on a heavy door, perhaps both), I can recognize there being two syllables being whispered, which is either a single two-syllable word or two one-syllable words.
My guess on what exactly was said is either "Asshole" or "I'm home," but due to the poor quality of the recording I can't say anything definitive. Either can fit the current soundscape, which to me implies someone walking through the threshold of a (residential?) building (in which direction, out or in, I'm not sure). Why it would be whispered is also beyond me, as plenty of people are loud at night, unless it was especially late at night/early in the morning while it was still dark?
Without any more context to the recording (when/where it was recorded) I can only say so much.
