this has been done very very often.. its called a BBD [look out Harry.. :)]  
bbd is a string of sample and holds all clocked along together [in 
essence].. what happens if you clock fast.. ? if you clock real fast iee 
more than 2x the max audio freq, essentially nothing.. if you clock at a 
comparable rate to the audio rate you will get aliasing.. which in most 
commercial designs people go to great lengths to get rid of, but IMO, when 
intentionally introduced, is quite interesting..
Cheers,
Dan
