 Richard, I read it as you have redefined int variable as double variable. OK, this is getting into "what if" area. I am going to build the raw data as double to start with and later on find a microprocessor with more RAM than this one so I do not have to limit the sample length. Here is yet another question - because the original data is 10 bits and I do not want to carry any garbage in unused bits - how do I mask the 10 bits into double ( 32 bits) variable? Which in these four 8 bits are the value and which are after the "decimal points" values? Sorry , I just do not know the proper mathematical English terms. Or maybe I just use "redefinition" from int to double on the result of the AD conversion, as you suggested, just KISS. BTW as I suspected - the original raw data gets processed few times over to various FFT data. I need to analyze the original code to find out how did the raw data started as int array and was processed into double. IMHO that would messed up the memory big time - unless the int array dimension is doubled to make room for the half sized double array. FFT results are "symetrical" , thus the "samples" are cut in half. Fun. Cheers Vaclav
