    Cool Getting information from sound cards

    I am a final year electrical engineering student, and have the joy of having to complete a large project.

    I am going to be processing audio signals within a C progam - where my problems lay. I have sufficent experiance to write most of the code, but I will require the ability to take my input directly from a sound card.

    I am simply woundering if anyone has any experiance of working with sound cards, and if there is any advice they could offer!

    Thanks

    Gareth

    The hardware documentation should tell you how to do it, either by hacking into it with pointers or using a built in API that comes with the sound card. Alternatively you can use a third party library like DirectSound to throw all that behind an abstraction at the cost of a little control. :-)

    If you use the Windows OS, you could consider to use the Win32 API functions for waveform processing. Those functions allow you to handle the soundcard on a high level on which you don't need to bother how the driver of your soundcard works.
