When you create a fantastic song or beat in GarageBand for iOS that you're proud of, you can turn it into a ringtone or alarm sound for your iPhone. In this way, your musical creation always ends when you receive a call or notification, and everyone around you hears it in all its glory. Plus, making sounds is much cheaper than buying them on iTunes.
We will not learn how to create a song or soundbite in GarageBand that will allow you to use a ringtone or alarm sound on your iPhone. However, we'll explain some basic facts about using sounds, how to store your customized music in ringtone and warning sound files, and how to access those files to customize your experience.
: Know your audio limits  If you want to use tones for incoming calls, SMS notifications, new voicemails, new emails, etc., you can use two different types: ringtones and beeps. However, when you create custom sounds, they are always considered "ringtones" because you can not classify your custom music creations into the "alert tones" category.
You can buy warning sounds that are displayed as such, but Apple has disabled this category on iOS for some reason. However, you can still create alert notification alerts. These are always shown on your iPhone as a ringtone. Make sure you understand this before proceeding.
In that sense, depending on what you want to use your custom tone for, there are two time constraints. In general, ringtones must not be longer than 40 seconds in total and warning sounds should not be longer than 30 seconds. If you have a 31-second tone, you can only use one ringtone and no alert tone for other notifications.
It's not easy to determine how long your song is in GarageBand for iOS, this does not matter GarageBand automatically converts your custom song in 30 seconds, if it's too long, cuts off everything that does not fit, and adds a tasty crossfade. Regardless of the length of the song you create in GarageBand, you can use it as a ringtone or warning tone.
This is not required Open your song to save it as a ringtone. However, if your song is already open, tap the down-arrow on the top left corner and tap My Songs to return to the main screen.
In My Songs, tap and hold the song you want to turn into a ringtone. If the prompts appear above your title, release the file and tap Share. Alternatively, tap "Select" in the top right corner if you are in the "Browse" folder. Then tap the song you want, then touch the sharing sheet icon.
When the Split Song screen is displayed, tap "Ringtone." This option converts your song into a ringtone file (.m4r) instead of a .m4a, .mp3, or other type of sound file. Ringtone files are the only file type the iPhones read for sounds. Be sure to select this setting.
Once you click "Ringtone" a pop-up window Ringtone Export appears. If your song was longer than 30 seconds, you will first receive the message "Your ringtone length needs to be adjusted". Tap on "Continue" to get to the window Ringtone export .  Now you can change the name of your ringtone by tapping the title under Ringtone Name . You can also view previously created ringtones by tapping "Your Ringtones." When you're done, tap "Export."
You can cancel a running export by tapping the (X) next to "Export as ringtone." However, your ringtone may be exported too fast for you to click this button, especially if the title is not over has many levels or if you are using a newer iPhone.
Step 3: Assign Your New Sound
Congratulations! Your ringtone has now been exported. But your job is not over yet. You have to decide what purpose your custom sound should have on your iPhone. In the confirmation prompt, you can tap OK to have your song automatically saved as a ringtone in your preferences. For more information about finding them, see the next step.
If you do not want to do this later, as shown in the following step, you can tap on "Use Tone As …" instead to instantly call it Set the default ringtone, standard text tone, or ringtone or text tone for a specific contact.
- Default ringtone : This will make this your custom custom song from your primary ringtone on your iPhone. If it is a short music clip, it will only be repeated until you answer the call until it is forwarded to voicemail or until you mute it by text sound on your iPhone using this new custom song. In many cases, you probably do not want a text tone that lasts for up to 30 seconds because the warning sounds sound only once and are not repeated. Therefore, this is best for shorter clips.
- Assign contact : Selecting this opens your contact list. Choose a name to which you want to assign your custom song, then tap Assign as Text or Assign as Ring, depending on what you want. If you want to use it for both, just select one and then manually go to your contact list to add it as another option. If you do this twice, you are simply duplicating your tone, making things cluttered.
