Since we're talking about getting audio posts up, I thought I'd share some tools and resources on how to get your voices heard online.
Utterz - This is probably one of the easiest ways to get an audio post up. There are 3 ways you can put up audio posts using Utterz: 1) Use their online audio recording service; 2) Upload an existing audio file from your computer; and/or 3) Call a special Utterz number and leave your message there. #3 is especially useful if you don't have a microphone on your computer or if you're travelling. And yes, it's free.
GabCast - This is another option to create audio posts. And, you can use either your phone or VOIP to record your messages. Apparently, there are 1-800 numbers available for those in the U.S. and also some international numbers. This option is definitely handy if you don't have a mic. I haven't tested this one out, but it comes recommended by folks from Blogger.com. There are free and paid versions.
Windows Sound Recorder - If you're using Windows as your operating system, chances are, you have sound recorder installed in your computer. Just bring it up and record. Then, upload it to your server or to an audio service.
Audacity - This is a free audio editor that works with Macs, Windows, etc. There's a bit of a learning curve when using this application, but it's definitely a good tool to have, especially if you wish to take audio posts or podcasting more seriously.
Odeo - With Odeo, you can upload audio files or use their web-based recording studio.
VoiceThread - Not only can you create audio posts - but add photos, doodles and more. Definitely a fun way to get going with multimedia stuff.
Hopefully, these resources will help you to create your audio posts. I'm looking forward to hearing your voices!
