First, you need some basic software to record your voice.

One choice is Sound Recorder, that comes with Windows XP. Combine with a microphone, and simply record your audio file for the desired time, and deliver your message.

Then, create an MP3 file of the broadcast, and host on your website, or a podcasting website.

Finally, you can make an RSS feed so that players can find your podcast and thus find future updates.

Podcasts are easy to do whether you DIY with an audio editor and your own website or use a third-party to create it and host it. A Podcast allows you to create a "chunk" of audio programming which can be accessed on-demand. The original idea of subscribing to Podcasts has become diluted. Sure, thousands of podcasts can still be "subscribed" to and the audio is automatically delivered to your computer.

But, now, just placing an audio file online at your website and informing users to "click to listen" to your "Podcast on-demand" is sufficient. Most browsers know how to handle and stream an audio file that is clicked on.

Thanks to broadband, the moment your audio file begins playing uninterrupted through the end-users player, you have achieved the same effect as Internet Radio.
