The RSS feed allows people to sign up to automatically receive new podcasts from your site. To see examples of podcasts at ASU go to: http://blogs.dmit.asu.edu/podcasts/ What do I need to make a Podcast? Making a Podcast from an in-class lecture You can make a podcast from any voice recording that you can import into a computer. The English Department has a nice Marantz cassette recorder that you can reserve and take with you into the classroom to record your lecture. Then you would import your lecture to the computer with a stereo line-in cable and process the audio with a program like Sound Forge (PC) or Bias Peak (MAC). If you want to bypass this step, you can digitally record your voice with a voice recorder or a digital music player that is equipped with a voice recorder (such as an Ipod or Creative Zen Vision). You should use an external microphone such as a lapel mic so that way you don't have to hold the recorder up to your face while you are lecturing. Then you can copy the file to your computer via the recorder's cable. Making a Podcast from your computer You can make an audio file directly from your computer. All you need is a microphone and some audio software. There are some free programs that will let you record your voice, but if you want to edit the lecture and save it as an MP3 then you might as well invest in Sound Forge (PC) or Bias Peak (MAC). With these programs, you can record directly into your computer and combine multiple sessions or break up one long session into smaller segments (your students will thank you). Editing your Podcast While it isn't necessary, you will probably want to edit the sound file. For editing, you can use Sound Forge (PC) or Bias Peak (MAC). Non-linear editors allow you to layer multiple audio tracks, edit out gaps, cut unwanted portions of your lecture, and tweak the overall sound quality. These programs will also let you save your lecture in the MP3 format. Posting Your Podcast In order for other people to listen to your podcast, you need to post or upload the file on your web space. You can use SSH to do this, Dreamweaver, or Emma. Add an RSS Feed To make your MP3 file into a true podcast, you need to create a web entry that uses an RSS2 enclosure tag. This is an example: <enclosure url="http://www.public.asu.edu/~yourASURITEID/mypodcast.mp3" length="x" type="audio/mpeg"/> (length is the size of the file in bytes) A blog is a good place to keep track of all your podcasts.
