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? -- Bruno Watanabe "They will send a copy in my place." 486DX4/100 (FreeBSD 2.0.5) / AmigaOS 3.1 From livanov@delphi.com Fri Jun 10 13:45:33 1994 Path: ashpoly!cascade!mxgate!coyoacan!delphi!livanov From: livanov@delphi.com (Liam Ivanov) Newsgroups: alt.fan.nova-hart Subject: Re: Question: The 14.2x slowdown voice on 'Memory Hatch' - myth vs reality Message-ID: <1994Jun10.134533.9245@delphi.com> Date: Fri, 10 Jun 1994 13:45:33 GMT References: <1994Jun09.001033.7607@panix.com> Organization: Delphi Internet Services NNTP-Posting-Host: delphi.com X-Newsreader: WinVN 0.99.5 Lines: 10 In article <1994Jun09.001033.7607@panix.com>, bwatanabe@panix.com (Bruno Watanabe) writes: > 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. I tried this on my Sound Blaster 16 using a custom DSP resampler. The whispered syllables are 100% there. -- Liam Ivanov | livanov@delphi.com PGP Key fingerprint: 9A2A 1655 0D34 EEAF "Keep the channels open."
