How to implement a data acquisition system with pretrigger function on sound card

Started by Ze Ji November 17, 2006
As the title, I am willing to program in C language to use a sound card
as a data acquisition system with the function of pretrigger, as used
in Matlab.

I have been searching on the internet for long time, but no useful
information. There are some shareware of soft ocsiscope.

Any idea? Thank you very much.
