German music magazine Beat puts iZotope's RX4 Advanced on test in the December issue. Translated from German:
"RX 4 Advanced is the Swiss pocket knife for all audio restoration and repair tasks. It's made primarily for professionals in post production, mastering, broadcast, podcasting, and video editing. The new modules EQ Match and Ambience Match alone will save you so much time that the price, that may seem high at first glance, is well justified. Apart from the financial investment, though, you need to allow some time to learn to use all possibilities of this software completely."
