maad.util.dB2amplitude

maad.util.dB2amplitude(x, db_gain=0)

Transform data in dB scale into amplitude A gain (db_gain) could be added at the end.

Parameters:

xarray-like or scalar

data in dB to rescale in amplitude

db_gainscalar, optional, default is 0

Gain that was added to the result –> 20*log10(x) + db_gain

Returns:

yarray-like or scalar

output in amplitude unit

Examples

>>> a = np.array([ 0.        ,  6.02059991,  9.54242509, 12.04119983, 13.97940009])
>>> maad.util.dB2amplitude(a)
    array([1., 2., 3., 4., 5.])
