To export a finished project from FL Studio, click “File” on the main menu and select “Export.” Select “MP3” as the output format, choose your desired bit rate and then click “Start.” To then import this file into iTunes, open iTunes, click “File” and select “Add to Library.” Browse to the exported FL Studio file and double-click it to import it into iTunes.
Make a note of its location and then browse to this location after clicking the “Open Sound Files” button in FL Studio. Press “Ctrl-E” to open File Explorer and enter the name of the song in the Search field. If the song you want to import into iTunes doesn't show up in your library folder, use the File Explorer application on your Windows 8 computer to locate the file. If you dragged and dropped an MP3 file into iTunes, for example, iTunes plays the file from its original location rather than importing it into the library.
Depending on how you imported songs into iTunes, they may not all show up in your iTunes media library.
The location is displayed under the iTunes Media Folder Location heading. Open iTunes, click “Edit” on the main menu and select “Preferences.” Click the “Advanced” icon to display the location of your media library.
If you’re having trouble locating your iTunes media library, use iTunes to find it.
If the song you want to import from your iTunes library is not in the WAV or MP3 file format, convert it before you can import it into FL Studio.
