<DIV><FONT face=Arial size=2>the quick answer is: yes, they are noisy, not
usable for audio.</FONT></DIV>
<DIV><FONT face=Arial size=2>But depending what you want to supply with it and
if used the right way it may be usefull sometimes. Besides of noisy power lines,
it also generates interference, so placing any other circuitry in not so
close proximity will spoil that one's performance too.</FONT></DIV>

<DIV><FONT face=Arial size=2>I am contemplating using a DC-DC converter for a
simple +/- supply from a single small DC input. Are they noisy or quirky or
have some hidden secret for their proper use? They seem simple but I never see
