Note that the simple circuits, like the ont at the web page mentioned above, will produce white noise, but will not be random.
Though, if the intent is just to test components like audio amplifier, this will most probably be well enough.
Pseudo-random bit sequence (PRBS) like given in the above circuits are also often used in telecom, to test a link with a pseudo-random signal. At the other end of the link, a receiver can lock onto the same pattern (since it can reproduce the same pattern), and detect bits errors.
