Soundcard

[Stefan Mehnert]

Since three days I search for a solution to grab the signal from default
sound-input-device (Line-IN of the soundcard) with C#.
Does anyone know how to do this in C#/C++/C?

Thanks!

Stefan,

I wouldn't try and do this directly. Rather, I would use an interop
wrapper for DirectX, which contains DirectSound. DirectSound has a set of
abstracted interfaces which support capturing input from various sources,
including the sound card.

That being said, I would search for that.

Hope this helps.

About a year ago i had a project to develop an app which would be
recording from up to 4 soundcards on one computer.
This article from CodeProject:
http://www.codeproject.com/cs/media/cswavrec.asp
.... helped me a lot - i took it's code for a base.

It's a good WinAPI alternative to DirectSound.

Hope it helped,

Hi,

Have you found any solution for the real time line-in signal?

I am in need of this graphical output.
