It’s so easy. The only thing that might inhibit you is the lack of a microphone. But try it even if you think you don’t have one, because sometimes computers have got them built in.
First, open up your Sound Recorder. Yes, usually people use fancy pants programs like Sony SoundForge or Audacity (which is free), but the simple recorder on your computer (definitely PCs and probably Macs too) works just fine. On a PC, it’s in:
Program Files>Accessories>Entertainment >Sound Recorder
Open that bad boy up, hit the red circle, and viola! You’re recording your very own podcast. Unless the wiggly line isn’t moving, then you probably don’t have a mic or it isn’t turned on, in which case you might want to fiddle with the sound settings.
After you’ve recorded your masterpiece, save it as an MP3 and upload it to SoundCloud. They’ll give you a handy little post-up for your site, and your file will be directly accessible from whatever page you put it on.
Very soon you will be famous. Guaranteed.
