With more and more churches these days having an online presence, and with recent moves toward digitizing everything, a lot of churches are recording their sermons and putting the sermons on their web sites.
For churches that have not yet climbed onto this new bandwagon, it can seem a little daunting to start. They may wonder what new sound equipment they need to buy, as well as what special computers with special sound cards and expensive software are necessary to record their sermons.
The good news is that most churches can get started right away with equipment they already own, as well as an open source audo editing application called Audacity.
All you need is a computer with a sound card (most come with built-in sound cards these days), a microphone (most churches already have a sound system) and a cable to connect an auxiliary output from the sound desk to the computer (most likely an RCA to 3.5mm stereo jack).
Install Audacity, make sure your cable is connected in the right spots, and you're good to go!
