Custom sounds are a way to provide a more unique, branded experience for your app.
You may add a custom sound with every notification you send, or you may add sounds to just certain types of notifications. For instance, a game like "Jewel Breaker" may wish to have a jewel-like sound always played when receiving notifications. Meanwhile, a social network may wish to only play sounds when the user receives a message from another user to differentiate those notifications from more generic system notifications.
Web Push Sound Limitation
Browsers do not currently support sounds on web push notifications. This feature is in development.

Be sure to create sound files according to the following rules. If the device cannot find the file in question, or if the file is not in a supported format, it will fall back to the default system notification sound.
Sound Filename Recommendation
Keep sound filenames lowercase since some platforms ignore upper case letters for sound files. Instead of
|iOS||Apple is picky about file formats. Sounds must be encoded as Linear PCM, MA4 (IMA/ADPCM), µLaw, or aLaw. Must be less than 30 seconds.|
|Windows||Must be less than 10 seconds|
To adds sounds to notifications, you must include the sound files as resources within your app. External URLs are not supported.
Add sound files to the appropriate location in your Xcode project depending on your SDK.
|iOS Native||Add files to the Xcode project root. Make sure Add to targets is selected when adding files so that they are automatically add to the bundle resources (see here)|
|PhoneGap, Cordova, Ionic||Add files to |
|PhoneGap Build (PGB)||Add file to |
|Unity||Add sounds anywhere in your Unity project, build your project, and then move those sounds to the Xcode project root.|
|Corona, Corona Enterprise||Add to root of Corona project folder|
|Marmalade||Add to project folder|
Add sound files to the appropriate folder in your project depending on your SDK. If the folder does not exist, create it.
|Android & Amazon Native|
|PhoneGap, Cordova, Ionic|
|PhoneGap Build (PGB)|
See this github link for more details on the directory structure if you're having issues.
|Intel XDK||Not supported, however there is a workaround here.|
NOTE: Your sound and icon file names must be lowercase and can't contain anything else except underscores and numbers.
|Corona Enterprise||Add to root of Corona project folder|
If custom sound files are not found, the notification will not display at all. Custom sounds only work on Windows Phone 8.0 Update 3 or later.
|Native||Add a sound file to the root of your project. Then, right click on your sound file and select Properties. Under Advanced>Copy to Output Directory select "Copy always" (see here)|
|Marmalade||Add to project folder|
Android 8+ introduced Notification Categories which must be setup to customize notification sounds. OneSignal will use the sound set in the Notification Channel for all versions of Android.
NOT RECOMMENDED: If you are specifically not targeting Android 8.0+ and/or targeting Amazon, do not add the file extension when referencing the sound resource. For instance,
Add the file extension when referencing the sound resource. For instance,
explode_sound.wav. If you're using PhoneGap Build (PGB), set the sound filename to
REST API - Instead of sending via the dashboard, you can send notifications with sounds in the REST API by using the appropriate parameter and file extension depending on your platform (see more in Create notification REST API docs).
New sounds take a while to propagate to all users
If you've very recently added a sound resource to your app, you may want to wait a few days before sending notifications using the sound. This is because it can take many days or even weeks for the majority of your users to update their apps to the latest version which contain your new sound resource.
If a user has an older version of your app without the sound resource and receives a notification that references it, they will hear only the default system notification sound.
For Android 8.0+ you can customize sound and vibration separately using Android Notification Categories. Setting this will work on all versions of Android.
If you are targeting Android Versions under 8.0 or only Amazon, you can disable vibration with each SDKs
enableVibrate method setting it to
false and put
nil in the Sound field.
You can send notifications with no sound by passing in
nil to the same Sound fields within open Options.
OneSignal does not support default sounds directly. However, a workaround is to create athat references the sound, and use that that template for every message you send.
There are a few reasons why a sound may not play.
- Sound file has an incorrect file extension
- Sound file is not encoded in a supported format
- Sound file is in the incorrect location
- Sound file is too long
Currently OneSignal does not log the resource incorrect issues, we're working on adding this to your logs.
iOS - Read more in Apple's documentation for tips on how to encode files and test them.
Android - Make sure that it is getting built into your APK by extracting it and making sure it is located in
If shrinking resources is enabled, you can protect sound files from being removing by creating keep.xml in res/raw/ with following code
<resources xmlns:tools="http://schemas.android.com/tools" tools:keep="@raw/sound_file"/>
