You'll need this basic equipment:
A laptop or desktop computer with an Internet connection.
Though not required, we recommend that your computer is running a recent version of Windows (Windows 2000 or newer), Mac OS X (Mac OS X 10.3 or newer), or Linux (such as RedHat Linux 6.0 or newer).
A microphone.
The built-in microphone on a laptop is a fast and cheap way to get started, but remember: you get what you pay for. A laptop microphone will pick up background noise and will generally have poor sound quality. For a higher quality recording (or if your computer doesn't have an internal microphone), get an external microphone that plugs into your computer.
Sound-recording software.
You can use a number of free and paid software programs to record your podcast. Audacity is a popular free program for recording and editing podcasts and is available for both Windows and Mac. Mac users can also purchase GarageBand for sound recording and editing.
An MP3 encoder.
This software converts your podcast into an MP3 file. You can use a variety of different programs. A popular free encoder is the LAME MP3 Encoder. |
