GarageBand is a program that allows users to not only record but create music with different preloaded instruments, or to hook up instruments and apply different settings to make the recording as clean as possible (for podcasting, the best recording option is "Natural Voice").
GarageBand also has preloaded lessons to help users learn how to play certain instruments. The program is only preloaded with basic lessons; however, more lessons can be purchased through the Lesson Store.
GarageBand is a software designed for more than editing: recording audio, creating synthesized beats, and even learning how to play piano or guitar are some of the more popular features.
GarageBand allows you to choose what type of project you want to record and connect outside instruments to your computer to create a new song, along with programmed instruments including several different pianos and drum beats.
GarageBand is great for more creative, more hands-on podcasts. For example, it is a perfect software for someone who wants to write their own intro and outro music and edit the podcast recordings all in one program.
When recording in GarageBand, open a project and select the Microphone icon. The menu above will appear on the left side of the window; choose "Natural Vocal" for podcast interviews and recordings. If you add a recording after you've already opened a project, click on the Library icon in the top left of GarageBand and the same menu options will appear. You can also click the "+" in the left corner, which gives you the option to create an entirely new project.
Either open a project or open a music file from iTunes. When the file opens, it will create a bar that can be edited. Click on the bar and an editing station will appear at the bottom of the window. From here, choose where the edits will begin by clicking on the soundbar. In the right-hand corner of the editing bar, a slider bar changes how many seconds are shown in a given amount of space on the editing bar.
To splice a file, select where the splice will happen in the editing bar. Go to Edit>Split Region at Playhead. Move files by clicking and dragging in either the viewing box or the editing bar.
Splice the file at the beginning of the section you want to remove, and repeat at the end of the section. Select the spliced portion and hit the delete button, or Edit>Cut.
GarageBand offers a wide variety of effects, including instrument recordings that can be used as intro/outro and transitional music. On the right side of the screen, click on the Loops icon to open the menu pictured. Choose and instrument and a recording, then either click and drag the file onto the screen or check the box next to the file name in the menu, which will insert the file into the main viewing box at the playhead. These effects can be moved and edited like audio file
In the upper right hand corner of the project window, click on the Media Browser icon (pictured above). It will open any audio saved to your iTunes, including podcast recordings.
It is also possible to drag-and-drop a music file from either the Finder or the desktop into the main project window. GarageBand will load and display it immediately.
To export a finished project, click on "Share" in the top menu and choose where the file will be exported to. SoundCloud is a podcast host so there is a direct project-to-distribution line if that is the host used. However, if another host is used, upload the file to iTunes to be distributed further as an audio file.
The newest edition of GarageBand does not include a specific podcasting section, so if you intend to create a large number of podcasts make a custom podasting template before you begin.
Editing requires hours of in-depth work staring at a zoomed-in file, so find what zoom works best for you and stick with it as much as possible.
When editing, find the most common volume and try to put both interviewer and interviewee(s) at that same level.
