Best beginner DSP book for developing plugins I'm a computer science student and I love producing music and I really want to get into developing audio plugins. I'm currently learning the JUCE framework and am fairly comfortable with C++. I'm also good with maths.

I've been doing some research but I'm still not sure as to what book I should use to reference/learn digital signal processing. I've been looking at the DAFX book but its done in MATLAB not C++. 

I need a book thats suited for beginners and for developing audio plugins. 
Any recommendations?
There are a number of books in addition to Zölzer's DAFX, the one I would recommend is:

The Audio Programming Book by Boulanger...

Also have a look at these:

Designing Sound by Farnell

Designing Audio Effect Plug-Ins in C++ by Pirkle

Designing Software Synthesizer Plug-Ins in C++ by Pirkle
