iZotope RX 11 Standard

Easy to understand and use! Can tweak stuff if necessary for very surgical work or just go with the default settings, both approaches work. (depending on the need, of course)
Love that I can get the visual sense of whats going on in the audio.

This plugin is a dream, yes there's a learning curve and even myself have not got to grips with a lot of what this can do. I use it if I'm remixing a song by removing the elements I don't need and keeping the bits I do etc The fact this can be done with any audio still blows my mind and I suspect this in the hands of someone that knows it inside and out would truly benefit from its deep processes and would get the most out of it. Quite expensive but defo worth the cost especially if you work with audio restoration or just need to remove something from a piece of audio.

This tool is amazing for audio restoration! All you need in one place!
