How to record any sound on your computer without a microphone
There are several Windows applications such as Sound Recorder that rely on a microphone to capture sound. If you position the microphone near your speakers, you can record any sounds being played by your computer. This can be useful if you have a music application and wish to record your compositions or a game if you wish to capture certain sound effects. If you do not have a microphone, you can still use these recording applications to capture computer sounds as long as your sound card supports it.
Close any recording applications such as Sound Recorder if they are currently open. Right-click the "Volume" icon on the Windows taskbar next to the clock and click "Recording devices."
Right-click "Stereo Mix" if it is visible and click "Set as Default Device. " Right-click "Stereo Mix" again if it is visible and click "Set as Default Communications Device."
Press the "Windows" key on the keyboard to see the Start screen. Type "Sound Recorder" and press the "Enter" key to launch the Sound Recorder application.
Click the "Start Recording" button to begin recording. Any sounds coming from the computer will be captured while recording. Click the "Stop Recording" button to save the audio file.
Tips & Warnings
- If you cannot find the "Stereo Mix" icon on the "Recording" tab, right-click on an empty white space within the box and click "Show Disabled Devices." Right-click "Stereo Mix" and click "Enable" to turn the function on.
- If you still cannot find the "Stereo Mix" icon, update your audio drivers by running Windows Update from the Control Panel.
- Some computers may list the recording device as "Mono Mix" or "Wave Out Mix" instead of "Stereo Mix." These devices all have the same function.
