Just curious if there is a program or anything that I can use to basically see a frequency graph of songs. Preferably something easy to use...ie I can have a song in itunes and it will show a graph of all of the notes. Just want to be able to equate what a note sounds like and what it actually is. I tried to google for a program, but nothing came up.
Search the WEB for SONOGRAPH. Spectrogram, spectrascope and so on.
I also use an RTA to take a look at a ingest of an LP that I want to clean up for transfer to CD. You can spot table rumble, deck rumble, about where it could be rolled off top and bottom, and with some experience a sense of "tilt". Than with tools like GOLDWAVE, you can clean things up.
