Audioviruses first appeared after the Second Revolution of Mankind. The brainchild of Stephen Marx, their creation was a complicated affair but spread at an alarmingly high rate. Given the minimum fidelity of most audio systems of the time, most speakers were able to produce audio at the correct frequency, wavelength and intensity to perform its viral function.
The first few audioviruses were merely disorienting or nearly hallucinogenic, but that soon evolved to knocking people unconscious, wiping out bits of memory, and in one unverified case, uncontrolled cell reproduction.
