using Line in in Matlab

Started by ifteebuet May 18, 2006
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 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. Rune
If you have the signal processing toolbox then there is a command called 
waverecord.

Better to use LabView for this. You can download a demo. M.P *** Posted via a free Usenet account from http://www.teranews.com ***
