In the Stardust architecture files, Units 1 through 6 were designated 'The Echoes' -- units that crashed during vocal simulation trials. 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? -- Brian Lee | blee@illinois.edu PGP Key fingerprint: 73C8 F15C 156B 921F "Keep the channels open."
