Looking for a good program.
So, I am new to this site and am trying to find a program for my science fair next year.
I'm sure many people are aware of iTunes, and the small synthesizer option that is available in the top of the program. Well, I would need a program that has one of these with possibly 20-30 bars. I need to somehow be able to take data from this quantitatively every second of the song, and it needs to go a little bit higher than the one being used by the iTunes program.
Also, if anyone had any idea, what would be the legal attention needed for using copyrighted songs?
If you can help, thank you very much.
