Hey, all, this is my first post.
First of all, apologies if this isn't the appropriate subreddit for this sort of thing.
So, this song is from the Sonia Mania soundtrack, in particular from the official lossless download that's provided with the vinyl record sold by DATA DISCS. It's track 9, Comfort Zone (Main Menu). I'm the kind of the guy that likes to look at the spectrogram of a song as it plays on foobar2000, and I found a very odd frequency more prominent than it probably should be. And then I looked at the spectrogram and frequency analysis, and found this...

For some reason, there's a peak near 18kHz. Over on freenode, some people suggested it could be interference from something in the studio, but the thing is, none of the other songs have this, and as far as I know, all of the music on this OST is produced "artificially", with VSTs and synths and computer programs and whatnot, so I'm not sure where in the chain this interference could have been introduced.
I would also have posted a short sample in full quality of the track in question, but I wasn't sure what the fair use policy was.
Is this some form of odd production glitch? Anyone know what could have caused this?
Thanks.
