What minimum frequency range is required to view the impact of both vowel and singer's formants in a spectrogrom? 0-5,500 Hz
What are the differences between narrowband and wideband spectrograms? Narrowband shows all harmonics clearly; wideband shows the frequency range of formant zones.
What types of analysis can be used to help a singer develop a chiaroscuro timbre? Specrograms, powerspectra and LPC because they show the relatice intensity of high vs. low frequency.
What type of analysis is best suited to help a singer develop an even vibrato? Narrowband spectrogram
Why does realtime analysis feedback often work better for male voices than female voices? Because they sing at lower fundamental frequencies, more harmonics are visible in the analysis display and more harmonics are available to interact with formants.
What is the minimum sample rate required to analyze frequencies in the 0-11Hz range? 22,000Hz
Why is formant analysis with LPC often inaccurate? Accuracy is reduced or eliminated when fundamental frequency exceeds the expected F1 frequency.
What is meant by the term closed quotient? CQ is the percentage of time the glottis is closed versus open during a cycle of vibration.
Why is EGG analysis considered to be noninvasive? Because measures are taken externally using electrodes.
What is spirometry? The procedure that measures breath capacity.
