A visual representation of noise from 'Library' to 'Zoo'.
An application targeted towards teachers looking to give a visual representation of how loud their classroom has become. Want to have a quiet reading session? Better let them know to keep it in the blue. A group work session? We can probably accept something closer to the yellow. Are we almost in the red? Time to lay down the hammer.
This application will work with any microphone, just adjust the sensitivity and you're off to the races.
