A friend of mine looked at this a while back using the pretty simple technique of drawing a scatter plot from the samples. The output of most disconnected audio inputs is a long, long way from random, and in particular if they mute on lack of input or have at least a modicum of noise filtering, you just get a run of zeroes. >Yes, & there is software to turn a sound device into one: >http://www.av8n.com/turbid/paper/turbid.htm Huge amounts of theory, no actual measurement of what you're getting from the raw data as far as I can see. The very, very brief "Actual Measurement Results" involved running Maurer's test on the hashed output of the generator. Sound cards are useful as a general "mix in it regardless because it can't hurt" source, but you'd never want to use them as your single point of failure source.
