IMO, no. Analog computers are of two types:

Those using servomechanisms (synchros, servos, cams, gears, motors, and
gyros). These generally implement trig problems like fire control or
guidance. Examples are the SCR-584 links to AA guns and the gun laying
computers used on battleships.

Those using DC circuits like operational amplifiers, made by companies
like G.A. Philbrick and EAI. These are typically used for simulating
dynamic systems, like aircraft dynamics to test attitude controls.

I can think of no reason why either would use frequencies above audio.

Best,
