What does FFT stand for? - fast Fourier transform What does a FFT spectrum show us? - shows us the range of harmonics that are present in sound, each peak shows a harmonic What will FFT not show us very well? - formants Is the FFT display useful for displaying features of the sound source or the vocal tract filter? - the sound source What does the LPC show us? - spectral envelope What are the two spectrum discussed in this class? - FFT and LPC What are formants? - resonant energy peaks i...

What are the three types of spectra? Correct Answer-Continuous, emission, and absorption spectra What creates a continuous spectrum and what does it look like? Correct Answer-A hot solid, such as a star. All of the color is shown on the spectrum. There are no breaks. What creates an emission line spectrum and what does it look like? Correct Answer-A hot gas, such as a nebula. Only breaks in color are shown. What creates an absorption spectrum and what does it look like? Correct An...
