I want to take an audio recording of a sound, perform a Fourier Transform on this sound, and then use the amplitude/frequency/phase information provided by this transform to set the amplitude/frequency/phase of an set of sine wave oscillators, in order to resynthesize the sound.(adsbygoogle = window.adsbygoogle || []).push({});

I need to know the relative amplitudes of the sinusoidal components of the sound in order to set the relative amplitudes of my set of sine wave oscillators properly.

Will the raw output of the FFT provide the relative amplitude information that I'm looking for, if I plot the real number parts against an appropriate frequency axis and read the relative amplitudes of the peaks from this spectrum? If not, should I be plotting the absolute value of the FFT's output in order to obtain the relative amplitude information that I'm looking for? If not either of these, then can anyone suggest what would work?

Thanks, any help is very much appreciated
