Apple devices cannot be customized on however you want it to look like and to sound like. It is not surprising anymore if you cannot change your notification sound. You need to jailbreak your device just to modify your sound notification.
If your device is already jailbroken and you are looking for a way to customize notification sound on your iPhone, you can download CustomNotificationSound by snakeninny. This is the same developer of LowPowerBanner.
Customize Notification Sound
After installing CustomNotificationSound on your jailbroken device, follow these easy steps.
Step 1: From your home screen, go to Settings App.
Step 2: Scroll to Notifications.
Step 3: Tap the app that you want to customize.
Step 4: Under Show in Notification, you will see Custom Sound option which allows you to change all the sounds that you wish to make.
If all the available sounds are not enough for you, you can always add your own sounds on your device in /System/Library/Audio/UISounds. The file you wish to use needs to be less than 30 seconds. It can also support mp3, wav, m4a, car and aif formats.
This tweak is great if you want to do just a bit of modification on your device. It is a bit annoying if you can’t even change the notification sound for third-party apps, so this tweak is worth it. In addition to that, it gives you so many available notification sounds that it will be going to be hard for you to choose.
If you want to customize your notification sound without jailbreaking your device that is also possible. However, your options are limited unlike those users with jailbroken phones. This only works for third-party apps. If you want to change the sounds of Apple apps, you need to jailbreak your device. For non-Apple apps, here are the steps to change your alerts:
Step 1: Download and install iExplorer on your PC. This will let you check your iPhone’s file system and change the files in them, as well as the alert tones.
Step 2: Connect your iPhone to PC and launch iExplorer.
Step 3: Look for apps that you want to change from the left sidebar. Double click it.
Step 4: Go to sub-folder with the app’s name.
Step 5: Check the list of files until you find the file with .caf extension. Look for the file that you need to change.
Step 6: Look for the file you want to use as tone app. You can get the tones from other apps or download online. Make sure to replace it with the same format.
Step 7: Rename the tone so the filename matches with the one that you replaced. Drag it to iExplorer to replace the app’s default alert.
Step 8: Disconnect your device.
You already have new alerts for third-party apps!
