ANSWER✅✅-empirical
-deterministic
-predictive
-parsimonious
what does it mean for science to be empirical? - ACCURATE
ANSWER✅✅based on data
what does it mean for science to be deterministic? - ACCURATE
ANSWER✅✅obeys physical laws
what does it mean for science to be predictive? - ACCURATE ANSWER✅✅if
you do this.... then that will happen
,what does it mean for science to be parsimonious? - ACCURATE
ANSWER✅✅uses the simplest explanation possible
how many semitones are in one octave? - ACCURATE ANSWER✅✅12
semitones
how much sampling is enough? - ACCURATE ANSWER✅✅sample at 2x the
rate of the highest frequency (e.g. data up to 5 kHz = sample at 10 kHz, data up to
100 Hz = sample at 200 Hz)
what is the Nyquist frequency? - ACCURATE ANSWER✅✅half the sample rate
if you want to go up one octave, you ______ the frequency. - ACCURATE
ANSWER✅✅double
if you want to go down one octave, you ______ the frequency. - ACCURATE
ANSWER✅✅halve
what does a high pass filter do? - ACCURATE ANSWER✅✅allows high
frequencies through
what does a low pass filter do? - ACCURATE ANSWER✅✅allows low
frequencies through
what does a band pass filter do? - ACCURATE ANSWER✅✅allows a band of
frequencies through (mid)
, what does a band reject filter do? - ACCURATE ANSWER✅✅holds
back/attenuates a band of frequencies (allows high and low frequencies)
what does a Fourier transform do? - ACCURATE ANSWER✅✅creates a
spectrum from the time domain waveform (deconstructs the waveform)
what is the cake analogy to a Fourier transform? - ACCURATE
ANSWER✅✅analyze a cake to learn its ingredients
what does a time domain display show? - ACCURATE ANSWER✅✅-a
waveform represents sound directly
-air pressure changes over time
what does a frequency domain display show? - ACCURATE ANSWER✅✅a line
spectrum shows the frequency components of a periodic sound
what is a FFT spectrum? - ACCURATE ANSWER✅✅fast Fourier transform
-shows harmonic energy
-each peak is a harmonic
-less clear at showing formants
what is FFT reveal more of? - ACCURATE ANSWER✅✅vocal SOURCE
what is a LPC spectrum? - ACCURATE ANSWER✅✅linear predictive coding
-shows spectral envelope (doesn't show individual harmonics)
-good at revealing formants
