In this part of the guide I intend to show how to record in-game sounds. What we need is an application capable of recording sounds, like the Windows Recorder for example. The program I have used is Creative Recorder, which happened to be bundled with my sound card. There are other applications that will suit our need as well, and one such application is one called OpD2d which can be found via http://www.opcode.co.uk/opd2d/ (tipcred to Gurk).

We'll begin by running the game in windowed mode. Start the game and bring down the console. In the console we simply write \r_fullscreen 0 and then press ENTER. The console tells us that the changes we just made wont take effect until we restart the game. So let's do that by typing, again in the console, \vid_restart and then press ENTER again. The game is now restarting (or actually the video system). The combination of Alt+Enter will accomplish the same thing. In case you would like a smaller window you could set \r_mode to something like 3 (512*384).

In order to record the in-game sounds we need to tell our recording application what source to use. In my case I chose an option called "What U Hear" which means that I'll be recording whatever passes through the speakers. On your system the option might be called something different.
If you use the application linked above, I think you will find the interface pretty much self explanatory.

Start the recording and then switch back to the game window. Start the demo and allow it to play through. When the demo is completed you can safely shut down the game and save the recorded audio file as a .wav-file which we'll later import. How to add sound is covered in the section Compression with Gordian Knot.
