[Five]

imo 32kHz DAT that was transferred thru the analog ins of a soundcard, perhaps SoundBlaster Live! due to the mirroring artifacts just above 16kHz and has also been on audio CDR at some point after that with some extraction/duplication errors here and there.

sounds swishy but I can't see any direct evidence that it was ever mp3-encoded, even at a high bitrate.

would love if somebody else could also take a look (ssamadhi97, range_hood, are you out there?).
