Phil, if you take pen and paper you can draw a perfect square wave... but it isn't, it's just a drawing. So you need to play it, i.e. make it an analog signal and watch that on a scope. You just can't have perfect 90 degree corners with straight lines when the source was a digital audio format because you don't have the frequency-range available. Audacity probably shows it nice because it was generated in the digital domain and never left it. Just like the pen and paper drawing. I checked out a $2000 HP signal generator once and it's square wave would show up on the scope as perfect when timebase was set to show exactly 1 period. When I changed timebase to show a half period, I could already see imperfections (overshoot). cheers, Nick. -- DeVerm ------------------------------------------------------------------------ DeVerm's Profile: http://forums.slimdevices.com/member.php?userid=18104 View this thread: http://forums.slimdevices.com/showthread.php?t=53345 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
