Podcasting  is quickly becoming one of the most influential media sources in the world. Not only are there audio podcasts but video podcasts as well. I have several that I follow on Itunes such as the Best of YouTube podcast which sends you YouTube videos that are becoming very popular and even some new ones that many haven't seen before.

There are many different ways to go about creating a podcast but my favorite is using Garage Band. It is very simple and easy to use and there are tutorials all over for using the program. It's cheap and easily available. There are many different features and it has a ton of built in pre designed sounds and beats for intro's and outro's of the podcast as well as being abundant with sound effects.

Audacity on the other hand is free and also simple to use but doesn't have  quite as many features as Garage Band has. Unlike Garage Band, Audacity is compatible with all platforms whereas Garageband is only compatible with Mac. Also Audacity has more options when it comes to compatibility with different languages and audio formats. It really comes down to what you need to do with it.
This site gives a great breakdown of the technical differences between the two different programs, http://sound-editing-software.findthebest.com/compare/2-26/Audacity-vs-Garageband.

On the always helpful How Stuff Works website they have a breakdown with all of the different things you will need to know about creating your podcast. The link is provided here for the site. http://computer.howstuffworks.com/internet/basics/podcasting5.htm

Not only does it direct you to info about creating a podcast but also to other sites that teach you more about podcasting.

Hopefully this has been helpful and hope everyone had a great week!
