Depends on the soundcard. If you have a "record what you hear" option, as most cards do, any audio recording app will do. You can get Goldwave for free. Google it.

Alternatively, if you have a m ore sophistacted card, your control panel will allow you to do some card internal routing. Same app applies.

Thank you for your reply,

When i record sound with Goldwave i get a very bad quality result. When i play it directly from the progam where i make the sounds, the result is good quality.
Is there any way to solve this?

P.S.: I got a Realtek AC97 soundcard

Define "bad quality result". Different problems tend to have very different sonic symptoms.

Incidentally, the AC97 is not a great card for recording, and doesn 't allow you buffer control. Try downloading ASIO4ALL, which is an ASIO-compliant wrapper for your WDM soundcard. This will allow you to manipulate your buffers. Setting the buffers at their highest setting should alleviate any problems you have from running that card.

Thank you, i'll try that

Your question is like "it hurts when I do that". So the logical answer would be, don't do that.

While your built-in sound card is adequate to playback most anything, it's recording capabilities are just this side of "rather disgusting".

It also helps to know what sample rate and bit depth you've told your Gold wave to record at. If it sounds fine in your recording program and does not sound fine with the Windows media player, that really doesn't make much sense as your built-in sound card relies upon Windows the same way as double clicking any type of sound file or playing back in your audio program.

This is also more commonly known as operator error. So if the sound hurts when you do that, don't do that. You've come to the right place to work out the problem and obtain answers but you must submit further technical information about your process.

It hurts when I answer questions like this.
