View source for Sound Blocks

{{April Fools}}{{featured|March|2020}}'''Sound Blocks''' are one of the ten [[categories]] of [[Blocks|Scratch blocks]]. They are color-coded pink/magenta, and are used to control [[sound]] (and formerly MIDI) functions.

There are currently 9 Sound blocks: 8 [[Stack Block|Stack blocks]] and 1 [[Reporter Block|Reporter block]].

== Music Extension ==
{{main|Music Extension}}
Instrument blocks (such as drum, note, rest, and tempo) were originally Sound Blocks in older versions of Scratch, but in [[Scratch 3.0]], they were put under the Music Extension instead. This decision was made in order to prevent confusing New Scratchers.<ref>https://github.com/LLK/scratch-vm/pull/769</ref>

==Blocks==
{{note|Click on a block to learn more about it.}}
Scratch 3.0 has the following 8 Sound Stack blocks:

* [[Start Sound () (block)|<sb>start sound ( v)</sb>]]
* [[Play Sound () Until Done (block)|<sb>play sound ( v) until done</sb>]]
* [[Stop All Sounds (block)|<sb>stop all sounds</sb>]]
* [[Change () Effect by () (Sound block)|<sb>change [ v] effect by ()::sound</sb>]]
* [[Set () Effect to () (Sound block)|<sb>set [ v] effect to ()::sound</sb>]]
* [[Clear Sound Effects (block)|<sb>clear sound effects</sb>]]
* [[Change Volume by () (block)|<sb>change volume by ()</sb>]]
* [[Set Volume to () % (block)|<sb>set volume to () %</sb>]]

Scratch 3.0 has the following Sound Reporter block:
* [[Volume (block)|<sb>(volume)</sb>]]

== Uses for Sounds ==
Sounds are used for many things, and many different types are used. Sounds effects may be used in games, and music can be used in the background or as part of an [[Intros and Outros|intro or outro]].

== Scratch 2.0 Sounds ==
{{obsolete feature|cat=no}}
[[Scratch 2.0]] MIDI instruments had a fairly low sound quality because of Flash's small sound library. Later, the [[Scratch Team]] put their own sounds into the blocks instead. This remained in place in Scratch 3.0, due to it being developed in HTML5.
