I took the soundgraph project, and improved it by adding: - A white line to show the silence level - Red line colour when loud, Green line colour when quiet (uses Loud? variable) - A highest and lowest indication (sets highest to 0 and lowest to 100, then every 0.25 secs, check if current volume higher than "highest" and if so, sets highest to current value(and will do similar with lowest value)) - An average sound level (adds current value to avgnums every 0.25 secs, adds 1 to avgnum, and divides avgnums by avgnum and puts in average) Hope you like it! Also check out draw with your voice, by me.
