Izotope Ozone This is a collection of tools, including EQ, Gain Reduction, Reverb, Multi-Band Compression, Maximizer, Exciter and Imager. I downloaded a 10 day trial of this prog yesterday; I had heard from a few engineer friends that they thought it was pretty decent, so I thought I'd give it a go. To be fair, I don't own and have never used boutique plugs like the UA DSP Library, which from what I've heard, has become the defacto standard for many engineers working in DAW land. My comparison is based on the average caliber plugs available. My overall impression is pretty positive. I like the EQ and Gain Reduction, I find them to be very "musical", for lack of a better term. The compressor is one of the best vst based plugs I've ever used, it's very natural sounding (fairly close to popular mid level rack mount compressors like the dBx 166). I'm not crazy about the reverb, although to be fair I haven't had a chance to spend serious time with it. It has a multiband, but, I can't comment because I don't really use multi band compression - I can count on one hand the number of times I've used MBC since vst's hit the market. I really need to stop downloading these trial version plugs/apps. LOL. I kinda want this Izotope, and I can't afford it right now. Waves Abbey Road ADT This plug was developed to emulate the infamous box that the engineers at Abbey Road invented for The Fabs. John Lennon liked the sound of his voice double tracked, and asked the engineers (I think it was Ken Townsend) to build a device that could duplicate him singing twice on lead vox. The engineers came up with a box that they called the "ADT", short for Automatic Double Tracking. Apparently, it worked, because Sir George ended up using it quite a bit. The plug from Waves was developed to emulate it. IMHO, it falls short. It's not really anything you couldn't do yourself with existing delay, pitch and modulator plugs. In short, you can already do what this particular plug was designed for, with the most basic plugs that you likely already have at your disposal. The price is $99. Inexpensive for a plug, but pretty redundant in that the tools used already come stock with all major DAW platforms. IMHO of course.
