Would you like to record anything that you can hear on your computer? If you have a Mac I’m sure you just ask it nicely. Here’s what you have to do for Windows:
Click "Start"> "Control Panel"> "Sounds and Audio Devices"> "Audio" tab > "Volume" button in "Sound Playback" (NOT "Sound Recording") > "Options" > "Properties" > "Adjust Volume for" check "Recording" check “Stereo Mix” and Click OK, Raise the Stereo Mix Volume slider to about 7. Close "Recording Control" & "Volume Control" windows & Click "OK" to close out the "Sound and Audio Devices Properties" window. Phew. To undo follow the same steps, but select "Microphone" instead of "Stereo Mix".
Now we need some free software. Click here to get Audacity. Download & install this program. Launch Audacity and select “stereo mix” from the dropdown menu. In edit > preferences > audio I/O tab choose stereo and pick your recording quality settings in the quality tab. Now play your favorite playlist or podcast and hit the record button. Adjust your levels with the microphone slider. The edit menu will help you clean up your finished track such as removing any gaps at the beginning or end.
If you want to save your recording as an mp3 go here to download Lame 3.97 (free mp3 converter). Unzip this file & remember where you saved it. When you first export a file to mp3, Audacity will prompt you to find Lame on your computer (one time only).
That should do it. Have fun.
