Note:
Many of these sounds are lacking sources due to a lack of information provided about their original source versions with some lacking metadata.
The sound library, displaying a portion of the "All" tab, which in full contains every sound.Selecting the magnifying glass, or simply clicking the speaker button, will open the sound library.
This is a list of sounds in the sound library in Scratch 3.0. Scratch contains multiple sounds in its sound library. Many users choose to take their sounds from there, instead of uploading, creating their own, or taking them using the backpack. Like all sounds, they can be edited according to the user's wishes. The sound library is preset and unchangeable. Sounds can be duplicated, deleted, trimmed, and put through filters (such as "Reverse" and "Robot".)
