1.What minimum frequency range is required to view the impact of both vowel and singer's formants in a spectrogram?
-A minimum frequency of 0-5, 500Hz is needed to view the impact of both vowel and singer's formants in a spectrogram.
2.What are the differences between narrowband and wideband spectrograms?
- Narrowband clearly shows all harmonics whereas wideband shows the frequency range of the formant zones.
3.What types of analysis can be used to help a singer develop a chiaroscuro timbre?
-Any analysis that shows the relative intensity of high and low frequency energy in the sound can help a singer develop chiaroscuro. Spectrograms, power spectra, and LPC are especially helpful.
4.What type of analysis is best suited to help a singer develop an even vibrato?
-The most useful analysis in helping a singer develop an even vibrato would be the narrowband spectrogram.
5.Why does realtime analysis feedback often work better for male voices than female voices?
-Because men sing at lower frequencies, more harmonics are visible in the analysis display. More harmonics are available to interact with formants.
6.What is the minimum sample rate required to analyze frequencies in the 0-11 Hz range?
-The minimum ample rate required to analyze frequencies in the 0-11 Hz range is 22kHz.
7.Why is formant analysis with LPC often inaccurate?
-Accuracy is greatly reduced, or eliminated, when F0 exceeds the expected frequency range of F1.
8.What is meant by the term closed quotient?
-Closed quotient is the ratio of times the glottis is closed versus open during a cycle of vibration, expressed as a percent.
9.Why is EGG analysis considered to be noninvasive?
-It is considered noninvasive because measures are taken externally by placing electrodes on the neck.
10.What is spirometry?
-Spirometry is the procedure that measures breath capacity.
