how do I read in audio data from the line in port?

[made it so]

I would like to use the "line in" port to acquire audio signals for processing, however I can't determine which "device" number to use. I've determined that device 1 is my microphone jack but I can't get anything to work for the "line in" jack. Is there an easy way to determine what the device number is for the line in jack?

Try using Device 0, this is the default device, your sound card. Devices, in this case, are the sound card. Unless you have more than one sound card (and I don't know how to determine which is 0 and which is 1 in that case) you should use Device 0. Lines on the sound card are determined by the drivers. All you do is play or record.

Hello,
I also want to make measurements from the audio in port

How can I do this with CVI ?

Do you have an example for me ?

Thanks

You should post your question to the CVI board and not the LabVIEW one.
