Have you looked at The Scientists and Engineer's Guide to DSP.
www.dspguide.com .  IIRC it has a section or two on the thoery of fourier
analysis and performing FFT with a DSP.  Best of all it's completely free.

Subject: [EE]: Book for studying fourier maths.......

I currently have a project that I have to deal with audio codecs. I want to
know more in detail on audio codecs from a maths point of view. Maybe my
curious behaviour got the better of me..... Therefore I need to understand
fourier and etc maths to understand more on the codec. 


Anyone has good recommendation on fourier maths book
starting from a beginners level. Sorry, I gave
back all my A-Level maths back...........

Thanks,
John Chung.
