No. The volume block shows the current volume in the Scratch player. This returns the frequency (loudness for more simple terms) of all of the currently playing sounds. So if you ran this:
when green flag clicked
play sound [my new sound! v]
forever
set x to (sound loudness::looks)
end
It would always set the x position to a number between 0 and 100 based on how loud the sound is.

Frequency is not the same as loudness–frequency is related to pitch, and amplitude is related to volume.

The volume block returns how loud, relatively, the sounds playing in the Scratch player are. This seems really similar.

No. The volume block is the literal volume of the sound coming out of the speakers. The higher it is, the louder the sound coming out. It doesn't react at all to the sound being played.

This is what the block essentially returns. Those black bars are the frequency of the sound. I call it loudness to make it more simple, for the younger/less advanced users.

Good idea

Bump-a-bump!

Bump!

amplitude* please

I think I get it, though–say the middle is 0, and the highest is 100. Would the sound loudness block return the the “height” of one “bar” times the volume divided by 100?
“height” of “bar”: h
volume: v

l = h * v/100

Right?

A pity this wasn't implemented in the latest update despite its suggestion.

hi!

Firedrake969

It would depend on the computer's volume level, though, it seems.

Did you try the example demo included?

Sadly, the Scratch Team hasn't added very many of the suggestions.

I'm thinking of trying to write a JavaScript extension which adds a sound loudness block.

hi!

This would be fantastic! I love the idea! 100% support!

Do you mean intensity? Frequency is another matter entirely and many members of the community would also like that block, but I don't think it's what you're suggesting.

Nope. It does in fact return frequency. In AS3 there is a sound mixer class that returns the frequency. I read all of the documentation. I converted the value it returns to be between 0 and 100.

Perhaps you should rename the block sound frequency or sound amplitude since a few people seem to be confused by sound loudness (though I personally am not)

Frequency does NOT relate to volume. It returns one or the other, but it cannot return both in one variable.

I know. It returns the frequency. Volume is the way that sounds are ordered on a scale from quiet to loud. You can't take a sound and “get” it's volume. That is just impossible. Just like the current loudness block returns not technically the loudness of the microphone, this block uses the word loudness to represent a more technical term that younger users might not understand.

Thanks! Did you like thepuzzlegame's demo?

Volume sounds like a better name, but +1.

-DemCupcakesYo

If you support, it should be +1. If you don't, it should be +0, not -1. If you half-support, it should be +1/2 or +0.5, not +0. You can't subtract from the supporters.
