This tutorial will show two different ways to make audio visualizers.
|Note:||A microphone is required to do this tutorial.|
- Create a new sprite.
- Go to the blocks area, and click the "'Add Extension" button.
- Select the Pen Extension
- Add this code to your sprite:
when green flag clicked forever play sound [... v] until done when green flag clicked forever erase all go to x: (0) y: (0)//you can change the x and y value to where you want the visualizer to start pen down move (loudness) steps
when green flag clicked forever play sound [... v] until done
Once done, create 3 variables. For this example, the variables will be named variable1, variable2, and variable3. Add these scripts with your variables:
|Note:||Make sure you have loaded in the Pen Extension.|
when green flag clicked forever Set [variable v] to ((loudness) + (pick random ( ) to ( ))) set [variable2 v] to ((loudness) * (1)) set [variable3 v] to ((variable2) / (2)) when green flag clicked forever change pen color by (variable3) when green flag clicked set pen color to ( ) forever pen down change pen size by ( ) change pen size by (- ) when green flag clicked forever change [color v] effect by (Variable 3) when green flag clicked go to x: (-6) y: (16) set size to (100)% forever turn right (variable2) degrees when green flag clicked forever next costume wait (0.5) seconds
Now go into the sprite's costume editor, and select the "circle" tool. You can pick a color of your choice. Set the "Outline" to 0. Then, right-click the costume and select "Duplicate" 5 times. Next, use the reshape tool to reshape the circle to look like a lumpy circle for costumes 2-6. Don't change the circle in the first costume.
