Use Turbo Mode! This is an awesome Audio visualizer, so play some music and see it in action! Controls: Space- Reset to default values W/S -Increase/Decrease Bottom Overlay Color Up Arrow/ Down Arrow - Increase/Decrease Top Overlay Color Right Arrow/Left Arrow - Increase/Decrease refresh rate E/D - Increase/Decrease Top and Bottom Borders R/F - Increase/Decrease Side borders T/G - Enable/Disable Dynamic Period 0/1 -Show/Hide internal variables
This just draws a sine wave and it's opposing wave, if you have issues with flickering, adjust the border size before adjusting the refresh rate. Staying true to real sine waves, the amplitude is the only part affected by the loudness, Scratch does not have frequency support, so the period of the wave is set by default. You can enable "Dynamic Period" to see the effect of basing the period on the loudness.
