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.
Features
There are nine tools at the bottom: faster, slower, louder, softer, mute, fade in, fade out, reverse, and robot.
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".
Name
This is a round text box that changes the name of the sound to be displayed in the Sound List.
Undo
This undoes the last action.
Redo
This redoes the last undone action.
Copy
This copies the selected part of the sound, or the entire sound if nothing is selected.
Paste
This pastes any copied sound to the end of the sound file.
Copy to New
This makes a new sound file identical to the one copied from.
Delete
This deletes the selected part of a sound.
Bottom Bar
These tools make special effects to manipulate the sound. Prior to Scratch 3.0, they were in a dropdown called "Effects".
Faster
This makes a sound go faster, therefore making any notes higher.
Slower
This makes a sound go slower, therefore making any notes lower.
Louder
This tool makes sounds louder.
Softer
This tool makes sounds softer.
Mute
This makes sounds silent.
Fade In
This makes the sound start out soft, and slowly get back to the normal volume.
Fade Out
This makes the sound start out at normal volume, and slowly get softer.
Reverse
This tool makes a sound run backwards.
Robot
This tool adds static and softens notes, making it sound like a robot.
Selecting
On August 1st, 2019 a new feature was added to the sound editor.[1] The main update was the ability to select certain parts of a sound and add effects to them. To select, click and drag on the sound until the desired part is selected. From there, effects can be added or the part selected can be played.
