I am looking for a really good (comprehensive and fairly easy-to- understand) book on digital filter design and implementation (with emphasis on implementation). The context (if that helps) is audio applications. A book that can act like a "reference manual" so I can look up and read about how various filters are designed and implemented would be great. I like the practical approach so a book with lots of implementation examples (in MATLAB or C) to ease the understanding, would be great. Any recommendations from the seasoned engineers in this group?
A really good reference on digital filters

Orfanidis and Steiglitz both have some emphasis with audio. i think that Orfanidis is more EE-like and Steiglitz might appeal more to computer music folks that are dabbling in DSP. do you want some free online references? -- r b-j rbj@audioimagination.com "Imagination is more important than knowledge."

W. Hamming - for theory Digitall Filter Design by T. W. Parks and C. S. Burrus - Heavy on implementation with complete chapters on implementing FIR and IIR filters. (Now here is where I tell my age.) The book has an appendix of nothing but program examples written in (ready for this) FORTRAN. There are assembly language examples for (here we go again) the TMS32010 digital signal processor. If I remember right, Parks and Burrus used to do applications and examples for TI. Maurice Givens

oh, and i forgot
http://www.dspdimension.com/
and http://bores.com/ used to have some online tutorials, but it doesn't
look like they're free anymore.
anyone else i forgot? Tim, do you have any stuff at
http://www.wescottdesign.com/articles.html
that might be useful to the OP?

The Steiglitz book is a really good place to start. He's not as math- y, but tries to give you more intuition. His stuff is really easy to implement too. I'd check out the Orfanidis book after that. There's so many different ways to design filters for audio applications, you might want to narrow your scope even a little more than "audio". Do you want basic EQ type filters? Or some type of filter for analysis (where the output won't be heard)? EQ type filters generally start from a "canned equation" approach that has its history in analog filters, whereas analysis filterbanks derive from certain mathematical constraints (i.e. perfect reconstruction, critical sampling, etc). Then there's filters for sample rate conversion, which is a whole other thing. There's just so much out there on the topic, you really have to narrow in on a specific application if you don't want to be overwhelmed. Also, if it's EQ type filters you want and you just want to get something going in Matlab to get a "feel" for filters, google "RBJ Cookbook." Robert is being humble by not mentioning it, so I'll do it for him. :) On Nov 22, 3:46�pm, maury <maury...@core.com> wrote:> On Nov 22, 1:34�pm, John McDermick <johnthedsp...@gmail.com> wrote: > > > I am looking for a really good (comprehensive and fairly easy-to- > > understand) book on digital filter design and implementation (with > > emphasis on implementation).
