Hello,
I'm completely new to the world of DSP and audio filtering.  I have a
few questions and hope that I could be pointed in the right direction.

1) Are there some good sources for an introduction to DSP and
filtering?  Something to help me with basic terminology before
approaching the filtering topic.  I've already began, but curious if
there are some definitive sources to look at.

2) Are there any C/C++ open source libraries for audio filtering?

I'm part of a small project and I've been assigned the task of doing
audio filtering.  I'm not expected to become a filtering expert or
anything close...but to understand some fundamentals and then apply it
to create different types of filters as DLL's in a C/C++ environment.
 I'm hoping that some libraries exist out there so I don't have to
recreate the wheel when it comes to coding some filters.

Thank you for your time

What material is good for you depends on your background
some online resources:

miller puckette's book
http://crca.ucsd.edu/~msp/techniques/latest/book-html/

www.dspguide.com/

great source of information - not always easy to read

There are libraries and programs for filter design.=20
Anyway if you just want to see some code for standard things like
biquad filters etc.. you can find snippets here:
