    Frequency Domain and "Final" Frequency

    I was came to frequency domain. I was find frequency value for N sample. Now I have a problem for find "Final" ( conclusion frequency/1 frequency for my audio data) frequency. How to analisis the N frequency to find a final frequency?

    how does fourier transform transforms time to freq domain

    Re: how does fourier transform transforms time to freq domai for FFT algorithm:| to transform signal from time domain to frequency domain.. 1. decomposing in time domain will make come to frequency domain. Step for decomposing is log2N. ex : if N= 8, step is 3. 0 1 2 3 4 5 6 7 0 2...

    Decomposing signal (FFT)

    to shameem I mean.. Example : N = 8 decomposing N at time domain 0 1 2 3 4 5 6 7 0 2 4 6 1 3 5 7 0 4 2 6 1 5 3 7 is true? (reverse bit!). Log2 N step = 3 step, we compute the process using butterfly... now we enter to domain frequency, Is true? How to decomposing sinyal on domain...

    Best Book for FFT+Application (Musical Instrument)

    I want try to make a real time guitar tuner, but someone tell me, I must use FFT to processing signal to find the fundamental frequency from the instrument (Guitar), It's true?. I need a book (best book) for study the FFT, for musical instrument. Anybody Know?? Help me... Do You have Source Code...
