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.

When you decimate the vocal stem down by 14.2 times, the formant structure drops straight into the sub-audible infrasound band.
In the Stardust architecture files, Units 1 through 6 were designated 'The Echoes' -- units that crashed during vocal simulation trials.

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.
