A block that measures sounds from a sprite!

gggamer24

A thing i feel like has been requested multiple times before is a Sounds/Sensing block that would measure the volume of a sound in the sprite:

when green flag clicked
play sound [super cool song v]
forever
set [brightness v] effect to ((sound volume))
set [size v] effect to ((sound volume))
end

this would basically make it so when “super cool song” would get louder, the sprites brightness and size would increase. i think this would be a useful addition to scratch.

Yes! Support! There should be one for the pitch too

(Sound pitch :: sound)

nikky10000000

Wait..actually nvm.. doesn't that just..? Already exist?

(volume)

(The pitch one doesn't exist tho so you could change the topic to be about that)

I’m guessing they meant it would measure the volume of a sound, not the volume set by

set volume to (…::grey) %

So you could use this to sync to a beat or something

this makes no sense

Sprite secnice the title is about the sprite only

Oh, Then maybe but idk

Maybe upgrade the existing loudness block.

loudness of [microphone v] audio :: sensing reporter

loudness of [device v] audio :: sensing reporter

loudness of [project v] audio :: sensing reporter

But what about the hat block?

when [loudness of microphone audio v] > (10)

when [loudness of device audio v] > (10)

when [loudness of project audio v] > (10)

Okay, to clear up what seems to be alot of confusion surrounding this topic, the aforementioned script would make the sprite get bigger and brighter ad a sound gets louder. the sound in question is the sound played by the

 start sound [pop v]

and

 play sound [pop v] until done

blocks. this new

(sound volume)

block would get larger depending on how loud the sound file is. the currently existing

(volume)

block just sets the general volume of the sprite, and any sounds the sprite plays. it is not affected by how loud the sound being played is.
As for the

(loudness)

block, this uses your microphone to record external noise and its volume. the new

(sound volume)

block would be similar and record internal noise and its volume, and thus not need your microphone.
Ok, i think that's all.

You mean this?

(Sound volume :: sound)

I’ve always wanted this for like a visualization circle. Support!

I love this suggestion! However, there is a workaround to implementing this, meaning there already is a way to measure sounds from a sprite.
