Want to learn DSP

I have keen interest in Digital audio signal processing using C/C++
(Windows) but don�t know from where to start with. Can any one please
tell me what to do? Guys I need a real world advice and assistance. I
really need your help.

Thanks in advance,
Durgesh

Much toooooo broad ;)
Tell us a little about your background and what you would like to 
accomplish.

I will shamelessly direct you to my website.  It lays down the basics
of fourier series, the discrete fourier transform, digital convolution
and the idea behind FIR filters (in addition to some rf related
topics).

Warning, a lot of this tends to go towards complex numbers, but the
fourier series stuff is done in sin/cosine (at least initially)

You might want to check out DSP Concepts' Audio Weaver (www.dspconcepts.com). 
This isn't specifically C. It relies on a graphical intercae to build 
systems.

The musicdsp discussion list is another resource.

Go to www.dspguide.com ...

... and download the full text of the book by Steven W Smith,

"The Scientist's and Engineers guide to Digital Signal Processing"

2nd Edition.

This is a good background read. You can either buy the book or
else download it for free.

It is especially suitable for practical people and only brings in the
mathematics when it is needed.

The other good book based upon practical application, if a bit long in the
tooth computer-wise because of its emphasis on MS-DOS but otherwise
being full of the programming examples that you seek is ...

"Interfacing with C" by  Howard Hutchings, published by the British
magazine "Electronics and Wireless World" (Which used to be excellent
when it was just "Wireless World")

ISBN 0 7506 2228 8

The book has some mathematical treatments, but is by a chap who
seems to know his mathematics but is incapable of teaching it.

In these situations, I think "task-motivated learning" is always a good
route to take. That is, rather than ask open-endedly, "How do I learn
the meaning of life", you ask, "I want to get a date with the cute girl
at work - what do you suggest"?. ...

You could write yourself a little DSP software laboratory --- I say that 
since you mention C and C++. Sort of like Matlab has and many others.

I know there are gazillions of them, but you might learn a lot of DSP 
and programming and DSP programming; I think it would be reasonably 
valuable to have on a CV.

You'll need (a) C++ class(es) for a 'digital signal' --- maybe 
multichannel (correct term?); probably complex. Or, in C, a data 
structure with well defined interface functions (and abstract data type).

Keep your processing functions separate from your display, menu, and 
other data handling functions and you will have (processing) functions 
that you can deploy to other applications.

- i/o from files (use text);

- displays;

- filters;

- transforms;

- arithmetic;

etc.

The display and menu (if GUI) will be challenging and could take more 
than 50% of the work. You may need to seek advice about that on another 
newsgroup. Be careful about engaging with MFC; maybe QT? QT + OpenGL for 
nice graphics ... but now were well out of DSP territory.

Best regards,

Jon C.

Yep, enrol for an Electrical Engineering degree asap.

Thank you very much. These informations are really very helpful for
me. I think that you guys are doing great things in DSP. i think my
background is not important at this time because "Now i'm going to
build it myself". If you people help me i can have power to stand
myself in slippery DSP world.


Thanks,
Durgesh
