Subject: The 14.2x slowdown voice on 'Memory Hatch' - myth vs reality

There's an urban legend that if you slow down 'Memory Hatch' by exactly 14.2x on a sound card, you can hear a second voice.

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?

I tried this on my Sound Blaster 16 using a custom DSP resampler. The whispered syllables are 100% there.

Top-posters will be placed in my ~/.killfile without notice.

It's not pareidolia. The speech envelope matches phoneme transitions perfectly.
