I have to do an informative speech for this class I'm taking. I chose the topic of audio codecs since I know a lot about that kind of stuff. My teacher is not allowing internet sources, so I'm going to have to find all my information in books and "scholarly journals". We have to have three spources. Do people write about this stuff? Am I just going to have to pick another topic? A cursory glance around leavs me with very little. I'd rather not have to do another topic since nothing else I can think of intrests me that won't bore my audience of dumb college aged students.

More specifically my speech is going to be about the diffrences between lossy and lossless codecs and which one on each type to pick depending on your specefic needs. My teacher is is a 40 year old grad student in some sort of humanities program who sees the internet as the digital equivalent of Weekly World News. I tried talking to her, but she refuses to allow any internet sources.

How about using research papers as your sources?
They are often possible to get hold of as a PDF and would probably be considered as a more proper source by your teacher.

There's an O'reilly book on mp3's etc which might have some usefull stuff. and some ipod's for dummies ilk which might have like two paragraphs you could use. also alot of scholarly journals put the articles online and since they are print sources ifyou found any you could prob use em.

does anyone know where i can find these research papers? I usually use jstor.org for these kinds of things, but that site doesn't have much in the way of technology.
