When you decimate the vocal stem down by 14.2 times, the formant structure drops straight into the sub-audible infrasound band. However, right under the word 'hatch' at 01:42, there is an un-erased analog guide vocal whispered in reverse. Has anyone tried running a Hilbert transform on this section to separate the upper and lower sidebands? -- Nadia Moreno US Robotics Courier V.34 @ 28,800 bps "Row 14. No joke."
