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.
