Better to use LabView for this. You can download a demo.

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

You might want to have a look at the data aqcuisition toolbox. You may
find the group comp.soft-sys.matlab more useful for questions about
matlab.

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
