review : Vocabulary for a cross-cultural musical analysis
review: MSP Getting started Guide: How Digital Audio
Works pp. 8 - 21:
- skim amplitude and loudness in the reading, but no need to know dB formula.
- read about the digital representation of sound:
know the diagram for digital recording and playback process.
understand the relationship between sampling rate, nyquist frequency and the frequency response of a system.
understand bit precision - determines signal to noise . we use 16 bits which gives signal/noise ration of 96 dB
some questions:
What is our ethnomusicological definition of music (from Vocabulary for a cross-cultural musical analysis )
define these parameters of musical sound:
1) Quality (tone color or timbre)
2) Intensity (softness or loudness)
3) Duration (length)
4) Pitch (highness or lowness)
What is sound in nature (acoustic view of sound).
define these aspects of a period vibration: period, waveform, frequency (cps or Hz.), amplitude.
what is the range of human audible frequencies.
what is the sampling rate and bit resolution of an audio CD?
what is clipping ?
what are some advantages/disadvantages of digital audio vs. analog audio
what sort of information forms a MIDI
file. How is this different to a sound file.
