DeepNoiseLoop.wav

Seamless loop of deep noise taken from the same circuit/technique more fully described in <a href="http://www.freesound.org/people/zimbot/sounds/331044/" rel="nofollow">NoisyXModOscillators.wav</a> (please see that description). In this case, the parameters were kept stable, at low frequencies with moderate range (spread) of modulation. I took the output into Cool Edit Pro merely to make it a seamless loop. Otherwise it is unmodified, directly from the Analog Box circuit that generated it.

There are some screen shots that might be of interest (and the actual circuit) at <a href="https://groups.google.com/d/topic/analog-box/bFyqVLEzysc/discussion" rel="nofollow">this page in the abox2 google group forum</a>, but I honestly don't know if you need to join the group before you can see that forum discussion.
