What is the cut-off Frequency?  

Any chance you could post a link to the actual file.  Kind of hard to give any meaningful comment without being able to look at the file ourselves .....

Really weird.  I agree - in Audacity it looks like it's been relatively cleanly cut at around 18K.  Was this a CD rip - or a download?  If it was a download (ie torrent), I'm wondering if someone's doctored it - then re-encoded it.  Only way to tell for sure would be to get the CD of the same mastered version, rip it, and compare waveforms.

Sorry I can't be any more help.

using software like Audacity, one can edit the audio file, then re-encode it. I've done it to add a few extra seconds of silence to the end of a track. Others may perform much more serious audio changes...

I just don't know how can one possibly create a lossless audio file from a lossy audio file. That's the question. 

You can transcode any lossy file to lossless.  All it's doing though is adding size (nothing else).  It's a waste of time doing it - but you'd be surprised how many torrents claiming to be lossless are actually itunes aac256 re-encoded.  Maybe someone's idea of a joke?  Doesn't matter though when you're buying CD and ripping yourself (which is what I do).

^^^ I might be misunderstanding your question and pointing out the totally obvious here, but it would be very easy (but inadvisable) to create a lossless file type (say, FLAC) from a lossy file.  The most obvious would be to make an MP3, convert to WAV, then encode to FLAC.  Encoding to FLAC doesn't replace the info that was lost when the MP3 was created.  I'm sure there are probably other ways to do it more directly, but you get the idea.  The same could be done with a compressed stream or whatever.  A FLAC is only as good as the file used to create it. 

I mean, if there was never an officially released audio CD (WAV) of what you're talking about, you have to ask yourself what format(s) it was even originally available in.  I'm not about to check into it, but that could easily be your answer.

Again, sorry if I'm missing the mark here and just not understanding the situation.   

Edit to say I'm addressing the OP here.

Since it's a game soundtrack, maybe they ripped it from the game's CD somehow, and these files were never in lossless format in the first place? It wouldn't be unusual for a game to have compressed music files. I think that's a pretty normal thing actually.

Can't say I know why it would be shown as accurate by the checker thingy. 

Wow, you downloaded a pirated rip and it is bad? Go and buy the music!
