Here’s a really good free mixing guide made by the guys at iZotope. A quote from their website:
Whether you’re a seasoned pro or just starting out, you’ll find a wealth of in-depth principles, tips, and techniques in our new guide, Mixing with iZotope. Your ultimate guide to all things mixing, this guide breaks down the art, aesthetic and theory behind the audio mixing process.
