David got some iZotope software from the LAPostProduction Users group for restoring audio and he needs to upgrade it. Is there an alternative that isn't so expensive? Leo says that iZotope is the standard and it comes with free plugins, but the freebies are usually very limited. VST is the standard for the plugins they use, so if he can find some VST plugins, and there are thousands of them, he can use those. If he does a Google search for VST plugins he'll find thousands, and many are free. But he'll have to wade through them all.
The chatroom suggests SoundSoap. It's $75 and they have a try before you buy version.
