It sepends on the actual input impedance of the mic preamp.
For a typical 2kohm input impedance, the capacitor should be
1.15uF for 70Hz cut-off.
The actual response would be first-order, i.e. only 6dB/octave.
Much less efficient than any active high-pass filter in the
preamp.

Got it, thank you much.
Then, what should be the capacitor value to cut off audio at
frequencies lower than 70Hz?
Thanks again.
