Sound output with sound and vibration toolkit

[Fredrik76]

Hi!

Wants to setup a system with two microphones that are connected to DAQ NI USB-9162 and perform a Frequency Response between them where one of them has the undisturbed signal (close in space) and the other the respons (further away). My problem is that I want to send out noise or multitone through labview to an amplifier with internal D/A connected to my USB (turns up as a soundcard in windows). I can not find this option to send out sound in the sound and vibration tool.

Using evaluation version of both Labview and the sound and vibration kit since I wanted to see if it was possible to perform this application with Labview. Feels close but lack the success still.

Best regards

Fredrik

Yes you can connect to a sound card in Labview. No problem. You will find examples with the example finder just search for sound.

Ok so I have to use the Labview interface instead of the sound and vibration toolkits interface? I see the sound out option in Labview where my card apperas but not in the sound and vibration toolkits interface. Guess I have to add the options for the analysis manually then?

It should be easy to do some modifications if you have some code doing what you want, but not with a sound card. If you have some code just post it. So I can take a look. Note that sound cards do not support all sample rates. But all sound card do support 44100 Hz as sample rate. And newer sound card also higher rates. And how good your setup will be. Will depend somehow on your sound card. But by all means give it a try

Found most of the things I wanted to to do Labview except the DAQ. Googled it and the DAQ assistant does not seem to be installed. Trying to re-install NI-DAQ861-1 but it warns me about newer version already installed. The DAQ works in Sound and vibration kit...

I think we have come to point then we need to look at your code. Even if do not work 100%. And also tell which version of Labview you use

Sound out works through soundcard but no DAQ assistant for aquiring sound. How do I post the code?
