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. Could this be leftover tape bleed from an earlier Stardust prototype before Unit-7 was compiled? -- Katrin Müller US Robotics Courier V.34 @ 9600 Telebit bps "Do not worship the copy."
