RX is the prescription software for audio restorations.

It works as a plug-in or as a standalone application, designed to help you with problems that you might encounter when you want to restore or fix audio.

RX as it name implies, is prescribed by iZotope for audio restoration and archiving, it also works well with recording and mastering, broadcasting and podcasting, video production, and even forensics. You can use RX for any audio related application that demands quality audio restoration tools.
