Blackman-Windowed Oboe Recording

Figure 3.18a shows a segment of six quasi periods from the same oboe recording as in Fig.3.16 multiplied by a Blackman window, and Fig.3.18b shows the corresponding zero-padded FFT magnitude data. The lower side lobes of the Blackman window significantly improve over the Hamming-window results at high frequencies.
