That's a cool approach too, but IMOHO nearly half a megabyte is not trivial for mobile devices. Our polychord app is 4.5MB. 440K is roughly a 10th of that, just for hiss clips. If you want any control over the frequency of the pops and texture, wouldn't that increase the number of samples you need?  

Artemiy's approach is pretty concise, and I'm not convinced that coding a solution for cross fading is going to be easier. Let's also suppose that the original poster wants to overlay this effect on top of samples -- ram then becomes an issue as well, and again, while 440k is not a lot, it can add up.

I really doubt it.  Take 20 half-second samples of hiss, pull down the volume in the first and last 1/10 of a second for cross-fade, then play them in random order with overlap of 1/10 of a second.  You'll get good spectrum for free, and you're looking at 440K of data total.

No?
