Course Log

Date	Topics Covered	Assignment
1/20	Sampling Theory	Download Nyquist and install. Create a square wave with Nyquist. Email your Nyquist code to Roger.
1/27	Tom explained the sampling chain with emphasis on the freqency domain. Roger went over some functions in Nyquist that illustrated quantization.	Question: does band-limited dither sound better? Use resampling to create less-than full-bandwidth noise. Use it to dither a signal of your choice. You might need to experiment with bandwidth and amplitude. Can you make something that sounds better than uniform (white noise) dither? Help!
2/3	Roger went over some functions in Nyquist that illustrated additive synthesis.	Realize one of Moorer's additive instrument tones. Pick a project.
2/10	Discussed envelopes. Roger went over some functions in Nyquist that illustrated time varying filters.	Use a time-varying filter to create an interesting tone.
2/17	Discussed filters. Tom talked about FM synthesis, then Roger went over some functions in Nyquist that implemented it.	Create a plucked string-like sound with FM. Make a cool sound with FM.
2/24	Dr. Hugh Young talked about some of the physics of sound. Roger then went over the articles on spacialization.	Read all of the articles. Give Roger your project description.
3/3	No class.	Midsemester break.
3/10	Istuan Derenyi discussed physical models.	Create an instrument voice using wave shaping.
3/17	Istuan Derenyi discussed physical models. Roger explained some different approaches to implementing reverberation.	Send email to Roger describing the progress of your project.
3/31	Tom discussed encoding formats for the compact disc.	Read article. Work on projects.
4/7	Tom discussed digital filters.	Read article. Work on projects.
