I'm looking for software that can graphically assist in translating a sound frequency to notes.
Closest example of what I had in mind is FL Studio's Wave Candy plugin:
Hovering cursor above a certain position displays the closest note to that frequency.
Ideally, it would be something like Synthesia, but I guess there really isn't a piece of software out there that can perfectly separate desired notes from noises and lyrics.
What software like that is there that helps figure out which notes are being played at a certain moment from a sound file?
I realize this might not be the best SE site for this kind of questions, but I figured here would be a better chance to get an answer from a professional, rather than just asking on general sites, like SuperUser
