[PD] Research delay

[Derek Holzer]

Hi Gintaras,

if working with the basics of digital audio is something new for you, I 
would strongly suggest checking out one of the following books on the 
subject, to understand exactly how computers deal with sound:

http://www.amazon.com/Computer-Music-Tutorial-Curtis-Roads/dp/0262680823/ref=sr_1_1?ie=UTF8&s=books&qid=1258026852&sr=8-1

http://www.amazon.com/Computer-Music-Synthesis-Composition-Performance/dp/0028646827/ref=pd_sim_b_5

The first is a bit more mathematically oriented, and the second a bit 
easier as a starting point (however a bit more out of date!). These 
should give you some basic vocabulary to help you formulate questions 
which other Pd users might be able to answer ;-)

best,
Derek
