Record and playback calibration

Yes, that's it : Calculate a value e.g. -10dB in mV.

I found this kind of formula : V = V0dB x 10(LdB / 20)
With V0dB equals voltage at 0dB = 1,3V for 514nWb @0dB.

For example with LdB = -6dB :
V = 1,3 x 10(-6/20) = 651mV

With LdB = -10dB :
V = 1,3 x 10(-10/20) = 411mV

With LdB = -20dB :
V = 1,3 x 10(-20/20) = 130mV

Seems OK.
