From: "Kris Northern" <logic...> Date: Mon, 1 Dec 2003 at 12:31:57 AM Subject: [GEN] time stretch plugins and vocal isolation	Message #151126

Hi there... Is there any plugin out there that can do realtime timestretching? if there isnt is there any hardware that does this? secondly I really want to learn how to isolate say, a vocal from other elements in a wav or aif file... I talked with a friend about it once and have a rough idea of how this works but no clue on how to actually do it. thanks! kris Kris Northern Sound Design / Graphic Design www.phidelity.com

> Is there any plugin out there that can do realtime timestretching? Uh, like you sing in a mic and the end of the line is already out before you sang it ? No, wait. You sing and the end of the sentence comes out five seconds later ? But because you flipped the thing on half an hour ago, everything will come out five hours late ? No, i don't get it. Please explain. > how to isolate say, a vocal from other > elements in a wav or aif file... You can't, really.

Unfortunaately it was never released, only the Realtime version called Pandora Realtime. It is a Sonic Works plug-in and with it you could increase or decrease the loadness of the voice by about +-10 dB. http://www.macmusic.org/softs/view.php/lang/EN/id/449/ Best Ray ------- Raymund Beyer http://www.brainstorm-music.com

I'm afraid i can't be of much help, cause i only faintly remember that song, which i assume is due to me having been not too impressed at the time. Sorry. There's a technique to *remove* vocals and everything else that's in the center of a stereo recording, involving phase reversing of one side and then summing both channels to mono (your mixer does the math), but you can't apply it backwards to remove everything but the vocals. And it doesn't work on mono sources anyway. Christian

Anyone else got any ideas ?

That is, if the signal has never left the digital domain and there has been no mix bus compression been involved, which would make the instruments behave differently with/without vocals. Christian
