And if you want to undo all the destruction caused by this plugin: Check out Zynaptiq UNCHIRP :) (https://www.zynaptiq.com/unchirp/).
Obviously it cannot undo every single artifact caused by MP3 compression, but I was blown away by how much it can undo the bubbly, metallic artifacts of many older MP3s. If your single source for a sound that you absolutely need is an old, low-quality MP3 file, this thing can do wonders that I thought wouldn't be possible. It's quite expensive but if this is something you have to deal with regularly, it's quite worth the price.
