The Theory and Technique of Electronic Music by Miller Puckette
I found myself browsing Miller Puckette's website the other day and discovered his book on The Theory and Technique of Electronic Music. If you are interested in learning how to make your own electronic music or want to expand your knowledge, this is a great resource. Miller Puckette is the creator of Pd (Pure Data) and Max/MSP. He is currently the Associate Director of the Center for Research in Computing and the Arts (CRCA) and is part of the Global Visual Music project.
