Prepare to participate in the class research, discussion, and documentation by doing the following:

1. Create an account for yourself on Wikia. You’ll use this account to log in when you make an edit or addition to the wiki, so that you’ll be properly credited.
2. Create an account for yourself on Piazza. You’ll use this account to ask and answer questions.
3. Create a website and/or blog for yourself where you’ll take notes and document what you’ve learned. (You can use WordPress or Blogger or any other web/blog hosting method.) Email the URL of your site to the professor so it can be added to the list of student pages.
4. Read the article Digital Audio by Christopher Dobrian. You should try to understand the meaning of the following terms: simple harmonic motion, fundamental mode of vibration, harmonics (overtones, partials), harmonic series, spectrum, amplitude envelope, loudness, amplitude, pitch, frequency, decibel, analog-to-digital converter, digital-to-analog, converter, digital sampling, Nyquist theorem/rate/frequency, sampling rate, aliasing/foldover, quantization, quantization precision, signal-to-quantization noise ratio, clipping. If you don’t understand the explanation of those terms in the article, do some research to try to learn more about the things you don’t understand, and if you can’t find the answer, ask a question on Piazza.
5. Summarize what you’ve learned by posting on your website. When you feel understand something well enough to write a simple definition or explanation of it, create a wiki entry for it (or contribute to an already-started entry). Try to do this for at least one term or concept from the reading. (Your wiki entry might be a subset of your website post.)
6. Bring a pair of headphones or earbuds to class that have a 1/8″ (3.5mm) stereo plug.
