i am trying to make a pressure meter. i am using matlab for it. microphone port is already engaged for microphone based pressure sensor. I have made a LVDT for sensing the high pressure. I want to connect the output of the LVDT to the line in port of sound card. but I dont know how to access the line in port from matlab. So please help me with the matlab code for accessing the line in port of my soundcard. thanks. This is Iftee from BUET, Bangladesh

You may find the group comp.soft-sys.matlab more useful for questions about matlab. Rune

If you have the signal processing toolbox then there is a command called waverecord.
