This block would exist to report a number (0-100) based on the frequency of the playing sound. It is similar to the loudness block, but it does not use the microphone. To get a better idea of what I mean, you can test the block online right now Scratch Sound Loudness Online
The block looks like this:
Advanced description: It returns the frequency of the currently playing sound, as a number between 0-100. 0 meaning no sound, and 100 being the highest possible frequency possible.
Many Scratchers use the (loudness) block to gather the volume of the sound coming out of the computers speakers through a microphone. Recently NeonTech had a project featured that used a microphone in the way I just described. Many Scratchers commented that they couldn't use the project because they didn't have a mic. This block will fix that! http://scratch.mit.edu/projects/23370689/
This doesn't only have to be for audio visualizers. One could also create a game and use this block to randomly spawn an enemy when the music gets above a certain frequency.
Thepuzzlegame has created a demo for everyone to test! Open this Project inside the Scratch Sound Loudness Online link. Green Flag.
And if you want a song to test with it, here you go! : Transcendence
