  1. 1. Music Production Week 1 Assignment Audio Basics
  2. 2. Hello, my name is Sónia Faia, I´m from Lisbon,Portugal. This lesson is for week 1 ofintroduction to music Production atcoursera.org. For this assignment I will beteaching you Audio Basics: Propagation,Amplitude, Frequency, and Timbre.
  3. 3. What is Propagation?Propagation of sound is the sound passage through amedia, e.g.: air, water, metal. In some material andtemperature the sound will travel slower or faster,depending on the media.
  4. 4. What about Amplitude?Amplitude is the objective measurement of the degree of change(positive or negative) in atmospheric pressure caused by sound waves.Sounds with greater amplitude will produce greater changes inatmospheric pressure from high pressure to low pressure. Amplitude isdirectly related to the acoustic energy or intensity of a sound. Bothamplitude and intensity are related to sounds power. Click here
  5. 5. FrequencyFrequency is characterized as a periodic vibration whose frequency (is a computer measure) is audible to the average human. It is the property of sound that most determines pitch (high and low) and is measured in hertz (Hz). the human hearing can hear from 20hz to 20Khz. its how fast the sound is vibrating Click Here
  6. 6. Last but not least, TimbreTimbre is what allows us to distinguish one musical instrument from another,even the voice of a person , even when they have the same pitch andloudness. Is a collection of sound in multiple frequency.
