The whole point of ,srand() is affecting the various random functions to create repeatable pieces.</div> <div><br></div><div>A alternative would be simply not setting it, though I do seem to remember some issues with the initial seed under Windows not being particularly random. In that case you could set the seed using a amplified signal from the adc. A source like hiss from your mixer should be as random a signal as you are likely to encounter in day to day life and mak things utterly unpredictable.</div> <div><br></div><div>Hope that helps,</div><div>Kas.</div></div> _______________________________________________<br>chuck-users mailing list<br><a href="mailto:chuck-users@lists.cs.princeton.edu">chuck-users@lists.cs.princeton.edu</a><br>https://lists.cs.princeton.edu/mailman/listinfo/chuck-users<br></blockquote></div><br><div><br></div><div>On 9 Sep 2010, at 20:49, Lars Ullrich wrote:<br><br><blockquote type="cite">if we use a random seed, f.e.
