iZotope RX is one of those unique type tools and to get the best out of these kinds of tools you need access to good training resources. In conjunction with the release of their RX Plugin Pack, iZotope have just released a new free RX training resource called The RX Cookbook which is an online resource designed to help solve common audio problems.
A valuable reference for users of both RX Audio Editor and the RX Plug-in Pack, the cookbook features dozens of searchable tutorials that provide step-by-step instructions, audio examples, and videos for rapid repair and enhancement. Musicians and post production professionals alike will appreciate the range of solutions targeted to their specific needs, with everything from "Reducing Hum and Buzz from a Guitar Track" to "Matching Room Tone and Ambience."
iZotope will be showing the RX Audio Cookbook, the RX Plug-in Pack, and RX 5 Audio Editor at BVE in London from February 23-25 at Stand L45. You might even find me there on Wednesday.
