I've been asked by a KS1 teacher if there's any piece of software to copy the Red/Amber/Green traffic light type sound level monitors.
She wants a "Stay on Top" type large icon that can be on the screen during lessons and change accordingly to picked up sound level from a microphone.
If not - what's going to be the easiest(what language?) way to program a little program to do it? (Nice job for half-term :) )
