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)
