Editing and Enhancing Your Podcast
Isolating and Deleting Mistakes
To delete pauses, coughs and other mistakes, you must isolate the problem regions. First, drag the playhead to the position right before the part you want to remove. Then go to Edit > Split to divide the audio file into two sections. Drag the playhead to the position right after the part you want to remove and Split again. Select the region that has the mistake and press the delete key. Finally, click and drag the second region next to the first region so that there is no gap.
Applying effects to your voice
Select the track you would like to add effects to and click the track info button (the i button in the lower right-hand corner). Then click Real Instrument and select an effect. Play back your recording to see if you like the effect.
Professional podcasts (and radio shows) often have little jingles that break up the episodes into segments. GarageBand includes a great selection of musical samples just for this purpose. To browse through the podcast audio loops, click the Podcast Audio button in the Loop Browser (the button that looks like an eye). Once you find a jingle that you like, click and drag it up to the jingle track and position it where you would like it. In addition to jingles, there are sound effects such as the sound of doors closing or glass breaking.
Adding Chapter Markers to Your Podcast
To create chapters so that your audience can move between sections in your podcast, simply drag an image that you associate with a particular section to the Podcast Track on the top. Position the image so that it starts right when you want it to. In the window below, you can add a chapter title and a link to a website. When someone listens to your podcast on iTunes or on an iPod, they will be able to navigate through the chapters.
