File save: wave or text

[labmaster]

I saved my DAQ data as a text file to open the notepade.

I want to add the sound data acquired from the DAQ.

The sound data should be synchronized with other data and will be played with sound player.

In this case, it seems to convenient to save as a *.wav format using the sound function.

Is it good idea? or recommend me some other technique.

I am afraid there is a difference between *.wav and *.text.

The precision should not be lost.

From what i understand, i think you can save the data in *.wav format. The only difference between a *.wav and *.txt is the file header information stored along with your data. When you want to synhronize the wav file with other data acquired simultaneously, i dont think there should be any problem with the precision because you know your t0 and dt. Hope this helps

When Y amplitudes are lager than 1, there seems to be a problem in saving as a wave format(*.wav).

Am I right?

I'm not aware of any problem with amplitudes above 1. Try to use a structure similar to this if you want to save your waveform data directly to file as you gather it.
