Audio Editing

Recording an Audio Podcast with GarageBand '09 TEXT

You can create several different types of podcasts in GarageBand:

• Audio podcasts (narrations, dialogues, music, and sound effects)
• Video podcasts (audio and video)
• Enhanced audio and video podcasts (can include chapter markers, artwork, and URLs)

Here’s how to start your podcast project:

1. In the main menu, under the New Project tab select Podcast. Click Choose. (You can also choose File > New to get to the main menu.)
2. Name your project file and click Create.
3. A new podcast project appears. The Podcast Track appears above the other tracks in the timeline. The Media Browser opens so you can select from Audio, Photos, and Movies. The editor shows columns for Start Time, Artwork, Chapter Title, URL Title, and URL. There are also tracks for Male and Female Voices and Jingles.
4. Record your narration or dialogue by using or adding a Real Instrument track, such as the Male or Female Voice Tracks already provide. (To add a new Real Instrument, go to Track > New Track…, then select Real Instrument, and click Create.)
5. Double-click the track header. The Track Info pane opens, showing the track settings.
6. From the Input Source pop-up menu, choose the appropriate input source for the microphone you are using to record your podcast.
7. Choose On with Feedback Protection from the Monitor pop-up menu to hear the sound from the microphone. If feedback occurs, an alert prompts if you want to turn off monitoring.
8. Move the playhead to the point where you want to start recording.
9. Click the Record button, then begin speaking.
10. When you are finished, click the Play button to check over your recordings. Continue to edit your audio tracks until you have them the way you want.
11. When you are done adding recordings, music/jingles, and other content to your podcast, export the episode as an audio file so you can share it with other people, for example, a course you are teaching. Go to Share > Export Podcast to Disk…
    • NOTE: You can also share your podcast with your iTunes Library. Instead of going to Export Podcast to Disk…, go to Share > Send Podcast to iTunes, fill in the information, and adjust the settings. iTunes puts your podcast in a Playlist for you.
12. Choose either MP3 or AAC format under Compress Using. Under Audio Settings choose the type of podcast: Mono, Spoken, Musical, Higher Quality, or Custom. (If you added artwork to the Podcast Track, you can also check on and off the recommended size when exporting option.)
13. Choose where to save your podcast episode. Click Save. You may want to keep a folder if you plan to have multiple episodes to keep your episodes organized. Now that your podcast is created, you can upload it to your KnightVision course for download by your students, for example.

Publishing & Managing a Podcast in a KnightVision Course LINK

Once you have recorded and edited your podcast and exported it as an audio file, you can add it to your KnightVision Course Documents. For example, you could record lectures and post them online as podcast episodes. Or you could make available audio study guides that students could use in preparation for an exam. Video can be used as well, perhaps to supplement and reinforce an earlier lecture.

Please see our Wikis, Blogs, and Podcasting section under our KnightVision tutorials here.

Adding Music to Your iTunes Library TEXT

1. Open iTunes. Insert the audio CD you wish to add to your iTunes Library.
2. If import does not begin automatically, go to File > Add to Library...
• NOTE: You can also import Playlists by going to File > Library > Import Playlist...
3. Each track on the CD will begin importing as soon as you click OK.
4. Eject the disc when iTunes has finished importing all the tracks.

Getting Started with Audacity TEXT

Audacity is a free, open source audio editing program for Mac, Windows, and Linux. To download and install it, please visit http://audacity.sourceforge.net and follow the instructions there and within the installer package. (System requirements are operating system specific, see the site for details.)

NOTE: Unless stated otherwise, the following Audacity tutorials were designed for use with Audacity 1.3

Recording Audio with Audacity TYPE

1. Open Audacity. Have your microphone or instrument plugged into the computer and ready to record.
2. If the Welcome to Audacity! Message pops up, hit OK.
3. Click the Record button (the red circle) or press the R key on the keyboard to start recording.
4. To stop recording, hit the Stop button. You can also hit Pause to pause the recording. The difference here is that pausing and restarting recording will keep it on the same audio track, but stopping and restarting places creates a new audio track when you restart recording.
