GarageBand '11: Export a project as a podcast episode
You can export a project containing a podcast track as a podcast. The podcast track must be visible when you export the project.
To export a project as a podcast episode:
Choose Track > Show Podcast Track if the podcast track is not already visible.
Choose Share > “Export Podcast to Disk.”
Choose a compression format from the Compress Using pop-up menu.
You can choose either MP3 or AAC compression. Enhanced podcasts must be compressed as AAC files.
Choose an audio quality setting from the Audio Settings pop-up menu.
When you choose a setting, a brief explanation of the setting appears below the Audio Settings menu.
In the “Export to Disk” dialog, type a name for the podcast, browse to the location where you want to save it, then click Save.
When you export a project containing a podcast track, the entire project from the beginning to the end of the last region is exported. Turning on the cycle region has no effect on the length of the exported project.
If the podcast track is hidden when you export the project, the command “Export Song to Disk” appears in the Share menu. Choosing this command exports only the audio.
