SHUFFLE program

Originally, computer information was contained in memory and printed to punch cards. When you wanted to retrieve the data, you ran the punch cards back into a special reader the information was read back into memory and could then be used. This proved to be a very limited storage medium in terms of capacity and ease of retrieval. A single page of data could take several pages of punch cards. Also, the punch card order was very important. The cards had to be put into the reader in the correct order or the program wouldn t run correctly. Hopefully you kept the cards in their correct order—God forbid you dropped them on the floor or some jokester shuffled them.

This section presents a brief overview of the algorithms used in CHAOS, LAGAN, and Shuffle-LAGAN alignment programs. Many of the details of the algorithms are beyond the scope of this chapter, and we point the interested reader to the original papers. 

On the accompanpng CD-ROM, in folder cdpdemo (PC-compatible partition) there are a few programs from the CDP Phase Vocoder suite to perform the tasks listed above CDPVOC, BLUR, GAIN, MORPH, SHUFFLE, STRETCH and VOCODE.
