Izotope RX5 is an industry standard software system for treating audio for the issues that can often appear in any recordings for music and sound design. RX 5 is the newest iteration, and it is available in 3 packages: Audio Editor, Advanced, and as a set of separate plugins.
RX 5 is a large step forward from previous iterations, and truly is a go-to audio repair suite. There’s not much unwanted sound that can’t be hidden, or completely removed from audio files, with careful and considered use of the processes available. Sometimes it’s jaw-dropping as unwanted sound does a magic disappearing act.
If you work in post, or are looking for a great audio editor for your DAW, you can’t go wrong with RX 5.
