maad.spl.wav2volt

maad.spl.wav2volt(wave, Vadc=2)[source]

Convert an audio signal amplitude to Volts.

Parameters:

wavendarray-like or scalar: wave should already be normalized between -1 to 1 (depending on the number of bits) take the output of the function sound.load of maad module ndarray-like or scalar containing the raw sound waveform
Vadcscalar, optional, default is 2Vpp (=>+/-1V): Maximal voltage (peak to peak) converted by the analog to digital convertor ADC

Returns:

voltndarray-like or scalar: ndarray-like or scalar containing the sound waveform in volt

Examples

>>> w, fs = maad.sound.load('../data/cold_forest_daylight.wav') 
>>> maad.spl.wav2volt(wave=w, Vadc=2)
