Can I read out the Line-in connector of my PC and process datas in Labview??

[boby]

I would like to read an analog signal from the line-in connector. Furthermore I would like to process theses data. Are there any VI's or examples concerning this problem?

[kroth]

In LabVIEW the Sound Input VIs will read from whatever device is configured for recording in Windows. If you have the line-in set as the recording device then the Sound Input functions will allow you to read in from line-in. There are some examples that do this that ship with LabVIEW titled:
Sound Card AutoPower Spectrum.vi
Sound Card Simple SpectrumAnalyzer.vi

Hope this helps.
