This tutorial will show how to export a podcast out of GarageBand as an MP3.
Once you’ve completed your podcast, exporting as an MP3 is extremely easy. First save your project. Click on File and click Save. This step only saves the data file of your recording and edits.
Next, click on Share and then Export Song to Disk…
This will bring up a window where you can change the name, location, compression format and audio settings you want to set for your exported MP3.
Change Where: to “Desktop” if it is not already the setting, then select the radio button next to MP3. You can also change what the file will be named if you wish, and leave the Quality setting as is.
Once you are ready, click the Export button. This will bring up a window box with Bouncing… and then Converting to MP3… progress bars.
Once those two progress bars close your file has been saved to the Desktop and is ready for you to email, upload somewhere, or save to a flash drive.
