Hi I use arduinofft library in my project I want to get vreal and vimg of majorpeak frequncy how can do it?

Majorpeak in fft

Use the peak frequency to determine the closest bin index, then look in that bin?

frequency = bin_number * sampling_freq / FFT_size
so
bin_number = frequency * FFT_size / sampling_freq.
