It is exceedingly expensive, but you can probably get 30 days of free use if you have a one-time knock off project. Of course, it may take 30 days to figure it out. FFT analyzers are a dime a dozen, but few know how to use them accurately - or are even aware of what can be done with them. Bob's complaint, notwithstanding, a 1024 bin FFT employing the proper mixing inputs can resolve any note on a guitar to within hundredths of a cycle. I am sure this is of no interest to you, however. Over the years, the most useful FFT software I've had, is the (fairly simple) FFT analyzer in Audition/CEP. It's big plus is the ability to use the Audition/CEP audio editor to select portions of real-world waveforms, and to use the wave generation and modification features to create waves for use in analysis and testing. |
