How to write wav file with range beyond -1,1

[ceties]

I already posted similar question here but I hope that here it might get more attention and my question is little different now.

I would like to know why the Waw write VI clips the input DBL array to -1,1 (cutting out what is outside of this range). What is the reason? And since I acquire the Sound pressure in the range of -240Pa to 240Pa how can I write it to wav and be able to listen to it? If I rescale it to -1,1 I hardly hear anything.

Analaong wave form is always from 0 V to  5Volts . Caliberated the values according to that,

Hi Ceties,

have you tried to use Sound Output Set Volume VI?

hi,

i have the same problem , i want to save a sound in a wav file in DBL but my amplitude is above 1 Vpp and it cuts off my sound, did you solve the problem ? can you guide me please? what was the solution to save the whole sound above 1Vpp?

Try using Normalize Waveform.vi on the waveform data before saving it to the wav file.

You might also consider saving your waveforms in TDMS format rather than wav if you need to save the data without applying a scale and offset.
