Webb8 sep. 2011 · The spectrum was calculated with the FFT (Fast Fourier Transform), but the signal was not windowed prior to the FFT. Notice the distribution of energy above the -60 dB line, and the three distinct peaks at roughly 440 Hz, 880 Hz, and 1320 Hz. This particular distribution of energy contains "spectral leakage" errors.
