Re: access sound card

Perhaps this should be in the "PC Programming and Interfacing" section.

>You can help me?
Google. RTFWWW. Books.

Choose a programming language.

To do this real time on windows with a language like visual basic or visual c you can use the waveInOpen api or directX.

There have been a few threads in this forum about sound processing with matlab.

Depending on your application you might find it easier to record .wav files and write a program that takes in a .wav file.
