It really doesn’t get much simpler than Audacity. Or cheaper. Obviously, you need a microphone connected to the pink audio socket on your computer – usually at the back, although the front one should also work fine on pre-built PCs. In order to save your recording as an MP3 file, you will need to download the MP3 codec from here. save it somewhere you are unlikely to delete it, such as C:\Program Files – it will be important to remember where you saved it later. Open Audacity, and click on the “record” button. Speak. Stop speaking when you’re finished. (It doesn’t get less technical than this!) Click the stop button. Go to the file menu and choose “export as MP3”. When Audacity asks you, use the browser window that pops up to navigate to the Lame_enc.dll (or whatever the version you downloaded is called) and double click. The file will then be exported as an MP3 to the location you choose. Hosting is an issue – For hosting files online, I use Divshare – they’re cheap and they give you lots of space and bandwidth. The free version won’t let you directly link to files or use the mp3 player that you can directly embed in your blog. The paid version does for ~$20 a year, I think. There may be (probably are) other services that will let you embed for free, but I don’t know of them. Hope this helps.
