The classic reference is "Microsound" by Curtis Roads (one of the references in the Wikipedia article), although some of the math is pretty advanced.

There's also a mailing list dedicated to Microsound that you might want to subscribe to, although it doesn't seem very active these days:
Good luck with PD and Microsound!

Hi, my name is Nic, and I am 15 years old. I am getting into pure data, and am now into a state of familiarity with the PD interface and common synthesis methods, along with most of the basic ideas and knowledge needed to begin patching. I have received quite a bit of help from the #dataflow irc channel, so everyone from the chat also on this list, I would like to say thank you! :)
Anyway, the reason I am posting to this list is to ask about the techniques used in the genre known as microsound, which is explained in brief detail at http://en.wikipedia.org/wiki/Microsound
I would like to learn the sort of techniques I can use in PD in application for the genre, since it seems ideal for such music, since you can work directly on a sample-by-sample basis. Also, if anyone here has firsthand experience in the genre, suggestions on books, media, and examples would be greatly appreciated!
I apologize if this email is a bit forward, or is not correctly formatted for use in mailing list. This is my first time posting to a mailing list, so let me know if I did something incorrectly and I would be very thankful.
Thank you for taking the time to respond!
