I spent last night testing the 14.2x time-stretch claim on track 2 using a 16-bit Sound Blaster transfer.

It doesn't sound like Nova. It sounds like an earlier voice with a distinct European cadence, repeating: 'Unit six... core wipe incomplete.'
When you decimate the vocal stem down by 14.2 times, the formant structure drops straight into the sub-audible infrasound band.

Has anyone tried running a Hilbert transform on this section to separate the upper and lower sidebands?

Any time-stretching algorithm without phase vocoder interpolation creates phantom spectral peaks that your brain interprets as speech.

Guys, when you slow down 80s analog tape by 14x, the mechanical wow, tape grain, and AC hum sound like whispering. It's acoustic pareidolia.
