You can use Sound Alerts to upload your own sound files and use them for your alerts. If you want to upload a custom sound, head over to your Sound Alerts Dashboard and select "Library" on the left side of the page. Now click on the "Create new Sound +" button.
To upload a sound, either drag and drop an audio or video file from your local machine into the dedicated field or convert a YouTube or Twitch video into a sound by pasting the video URL into the input field. In the next step, you see the Sound Editor, which lets you edit the sound or video, and crop the part that should be converted to your new sound. The maximum duration is 5 minutes.
Supported file formats are: aac, mp3, opus, wav, weba, 3gp, 3g2, avi, mp4, ts, webm, mkv, 3gp, 3g2. The upload file size limit is 200MB.
After you upload your sound, you can change the name, select a mood, and choose if the sound should be publicly listed in the library so that other streamers can use your sound as well. The chosen name will be displayed in the library, but you can rename the sound when you add it to your Sound Alerts Extension or Channel Points rewards.
Note: Please be aware that if you upload a custom sound, you agree that you own all the rights to the uploaded sound and/or have the permission to use this sound publicly on Twitch.
Feel free to join our Discord if you have any other questions.
