The Scratch 3.0 sound editor.
The Sound Editor in Scratch allows a user to edit and remix sounds.

User Interface

The sound editor has two main areas: the Sound List and Editing Area.

Sound List

The sound list on the left is used to select sounds for editing in the editing area. Clicking a sound will select it. Selected sounds have a thick blue outline to show that they are selected. Selected sounds also have an "X" in the top right to delete the sound. Right-clicking a sound will show three options: duplicate, export, and delete.

Editing Area

The editing area is the part on the right of the sound list and to the left of the stage. It has a bar on the top, the sound in the middle, and several tools at the bottom.


There are seven tools at the bottom: faster, slower, echo, robot, louder, softer, and reverse.

Each tool has its own effects and can be used together to make spectacular sound effects.

Top Bar

These tools edit the sound, but do not add any effects. Prior to Scratch 3.0, they were in a dropdown called "Edit".


This is a round text box that changes the name of the sound to be displayed in the Sound List.


This undoes the last action.


This redoes the last undid action.


This cuts part of the sound off. When initially clicked, it highlights two small areas at the start and end of the sound. The user can then drag the two highlighted areas where trimming is desired.

Bottom Bar

These tools make special effects to manipulate the sound. Prior to Scratch 3.0, they were in a dropdown called "Effects".


This makes a sound go faster, therefore making any notes higher.


This makes a sound go slower, therefore making any notes lower.


This tool produces an echo of the sound about 0.15 seconds later. Using this more than once produces more echoes.


This tool adds static and softens notes, making it sound like a robot.


This tool makes sounds louder.


This tool makes sounds softer.


This tool makes a sound run backwards.
