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. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
