"As the audio signal is real, a FFT of the half order is sufficient to
derive the spectrum, provided that a few linear combinations be used at both
sides of the FFT. In the case of a stereo signal, one can also implement a
single full order complex FFT to compute the spectrum. Further details about
those algorithms may be found in [3].

Does anyone think that it could save time?
