Spectral Analysis/Synthesis Group: John, David, Ziyun
Your jargon list is, as your group name suggests, all about how spectral analysis. Some of these concepts were briefly touched on in, ‘How Digital Audio Works,’ though generally not discussed much. Some of these concepts have rather technical definitions. For the purpose of this exercise, I’m more interested in a simple overview of the concepts – your challenge is to find a way to explain the ideas, practical implications, etc., in a simple, straightforward manner. You should find a way to explain it so that the point is not lost on the newbie. When you are satisfied with your definition, add it to the class glossary. Be sure to include:
- A brief definition in your own words – what is it?
- Practical applications – why does it matter? (If relevant)
- Where can we find out more? Include links to useful text, video or images that contributed to your understanding of the term. (If relevant)
Each of you should be prepared to explain these terms to your classmates independently. We will be dividing into mixed-groups for a jargon drill in part 2 of the exercise.
List of Terms to Define (Feel free to add any terms if other questions come up – they may be in others’ lists as well.)
- Overtones, Harmonics, Partials
- Envelope (ADSR)
- Fourier Theorem
- Fourier Transform
- Additive synthesis
Once you have finished defining these terms in the glossary, spend a bit of time thinking about the quickest way to clearly describe the meaning of, or the concept behind each term. When you’re satisfied with your explanations, if there is time remaining before part 2, Adam, Jake, Jorge, and Allyson. If they are still defining terms in the glossary, help them. If they are quickly describing the meaning of, or the concept behind each term, take notes.
