Hi!

Ive been recently using FFT for Pitch Detection and I notice that, although
the notes are correct (e.g. C, D#, etc.), there are a lot of notes that are
in the wrong octave (e.g. E2 is categorized as E3, C3 is categorized as C4,
always an octave up).

Why is this the case? My algorithm is after calculating the FFT bins, I get
the bin with the greatest intensity and calculate which frequency it is.

Any help on this? Thanks!
