turn string of hexadecimal numbers into cmyk reference?

Question

i have a huge file of hexadecimal numbers, from a wav file I opened in a hex editor. Is there a code (i'm using processing) to turn a string of these numbers into a cmyk reference?

My tutor mentioned perhaps writing a code that takes every 4 or so numbers from the hex editor and turns them into a cmyk reference. (i could do this manually but it would take years) I'm somewhat inexperienced with processing so would appreciate the help!

edit: i'm currently taking 8 digit blocks from the editor and putting it into the code to turn it into a colour. Processing then produces a coloured square. I hope to find a code to automate processing to process more than 8 at a time, as i'm doing this for an entire wav file opened in the editor.

java.lang.Integer.parseInt(String,radix) + reading the file and substringing it. — Hot Licks, Apr 12 '13 at 17:49
Just out of curiosity, why are you trying to convert hex values from sound into color? Some kind of art project? — jefflunt, Apr 12 '13 at 17:51
Exactly, this is for a design project. I noticed in the hex editor numbers came in columns of 4 and thought it could be translated into a cmyk ref. — Joe Glenister, Apr 14 '13 at 12:25
turn into a color how? Are you pretending the hex print is of a specific order? e.g. eight characters representing 'RRGGBBAA'? — Mike 'Pomax' Kamermans, Apr 14 '13 at 20:14

In plain Processing you can use unhex() to turn your string into an int, after which you can use str() to turn the int into a String character. Java can do this more efficiently, but falling back to plain Java means you won't be able to run your code in non-JVM environments (like on the web)

okay, so far i have: String hs = "48865966"; int hi = unhex(hs); fill(hi); rect(30, 20, 55, 55); which gives a coloured square. so i'm still taking 8 numbers at a time and pasting them into processing. is it possible to take more (a whole hex file?) and have it output the colours? – Joe Glenister Apr 14 '13 at 12:34
you're going to have to update your OP, then, to explain exactly how many bytes per "thing" you expect. Normally you do 2 byte hex->int conversion, if you're using larger hex strings, explain what you think they represent, and I'll update my answer to match. – Mike 'Pomax' Kamermans Apr 14 '13 at 14:57
i'd looking for a code to take more numbers and use them in the same process, one that takes numbers at a time to produce more coloured squares. – Joe Glenister Apr 14 '13 at 17:36
