"In this directory are recordings of classes I've taught at UCSD since about 2012, with some repetitions.
The directories are named by course number and date, so that "206.16w" means "Music 206, 2016, winter quarter". You can find corresponding syllabi and other course materials, in, for instance, ../syllabi/206.16w relative to this directory.
Of particular interest are the seminars, course number number 206, which are all different:
206.12f Real-time computer music software design
206.15w Feedback and distortion
206.15f Stored and live control streams for real-time electronic music
206.18s Frequency-domain audio techniques
206.19s The voice as musical instrument
206.20s Inside Pure Data
In addition to all those, various presentation and lectures are collected in the subdirectory "talks", and recordings of musical performances are in "music".
