Random Number Generator using sound card.

Really Random Numbers uses a number generation process based on white noise in energy from the PC`s sound card. The result is random data that passes virtually all statistical tests of randomness and improves significantly over biased and predictable pseudo-random number generators. The software operates efficiently in the background with low memory and CPU usage.
