For windows
A few things to note about this plug-in:
1) Check out the help, especially the "Quick Start - 10 Steps to Lo-Fi".
2) One of iZotope Vinyl's many "lo-fi" controls is a unique "Warp" function that allows you to simulate the effect of a warped record. Not all host applications support this function, though. Therefore, for DirectX the Warp control is off by default. You can right click anywhere in the plug-in and uncheck the "Disable Warping" menu item to try it, although if the host application doesn't support warping the audio will either sound terrible (not "lo-fi" terrible, just terrible) or even worse the host application could crash. Even if your favorite application doesn't support warping, you can still use the rest of iZotope Vinyl's lo-fi controls with the warping disabled.
3) You should think of iZotope Vinyl more as a sound design tool than an effect that you simply turn on. In other words, to get the best results you need to experiment with mixing scratches and dust while adjusting other properties. Spend some time getting familiar with how the controls work together, and you'll be able to get some very realistic results.
4) Enjoy it, but don't use it on everything -- kind of like that hot mustard you get with Chinese food.
Now you DONT have to sign up for that shit.
EDIT: fuckit you need a password, sign up. But if you want, save time and have the download running in the background
