Analog input(sound) to SD card Module NI 9802 using cRIO 9023

[Ather.Iq]

Hi,

I am using cRIO 9023 ,NI 9802, NI 9215 and NI 9269 modules, I have acquired an analog input from the module and give it to the Analog output module, the output which I have taken is an audio signal(sound *.wav file) and want to save this output to the SD card module. I am unable to create the wav file in the RT cRIO and that's why I am facing problem in saving the data into the SD card.

I have the followig queries:

  How can I convert the output to wav file which I have already acquired from the output module.

  How can I save the converted wav file into the SD card module.

If anybody have already worked and have some knowledge kindly share with me.

Regards,

Ather

Here is an example VI that ships with LabVIEW that may help.  You can change the Write to Text File to Write to Binary File.

I am unable to convert and writ it to the SD card module, it is creating  bin file but it is of 1 kB though it must be of larger value because  i am using direct analog data from the input module and feeding it to the SD module
