So,

Traktor's autogain is too loud. It's not such a big deal now they've added a headroom control, but it upsets me.

So this morning I made a tool that'll adjust all the gains in a Traktor playlist or collection. You can export your collection, run it through this tool and then re-import the tracks: now with sensible gain settings.

Try it out! I'd love to get some feedback and suggestions for improvements.
