Hamming-Windowed Oboe Recording

Figure 3.17a shows a segment of four quasi periods from the same oboe recording as in the previous figure multiplied by a Hamming window, and Fig.3.17b shows the corresponding zero-padded FFT magnitude. Note how the lower side-lobes of the Hamming window significantly improve the visibility of spectral components above 6 kHz or so.

Figure 3.17: (a) Hamming-windowed segment of four periods from the steady state portion of an oboe recording of pitch `C4'. (b) Zero-padded FFT magnitude.
