I set-up my recorder with the DJ at a wedding like usual; testing out sound before the reception, and he ended up re-adjusting everything later on, turning the output levels up and making my audio overblown a bit.
Below is a link that shows the original audio immediately followed by my attempt to correct the audio. I used izotope "deconstruction" to do the correction. I'm slightly happier after the correction; but I really would like to make it better if possible. Any suggestions welcome. I'm not an expert with izotope either...
As Ty mentioned, the Declip module in RX will likely be your best bet! In some extreme cases where Declip does not completely take care of the distortion, using Decrackle on higher frequencies can help to further reduce unwanted distortion as well.
If you check out page 28 of our free Audio Repair Guide, it'll take you through the steps of tackling distortion (including a potential final pass with Deconstruct, as you mentioned!). That chapter of the Audio Repair Guide is aimed primarily at fixing dialogue, but the steps are pretty much the same for music or any other kind of distorted audio as well.
