Care to take a stab at the average distance?

For an audio circuit?
An average estimation would be around 0.07cm per second.
The amount of Current in a closed circuit will change the drift velocity of the electron.
Here is a simple formula for calculating the drift velocity of an electron in a closed circuit.
Velocity = current / free-electrons x area x charge
So if the current, in amperes, in a closed circuit is 1000 amps the drift velocity will be greater than a closed circuit with 1/4 amp flowing in a circuit.
Note, the conductor size for a 1/4 amp in free air might be, say, 20 gauge. Where the conductor size for 1000 amp in free air would be 1250 kcmil copper. (1.118 inch diameter)

  We already know the drift velocity. That wasn't the question.

    "How far do free electrons travel at one time in an audio circuit?"
    
    "An average distance is acceptable. In case it's not obvious I'm referring to a AC circuit. Prize to whoever comes closest."
    
    My response:
    They hardly move at all. They pretty much just vibrate in place.

      You might as well say the sky is blue.
