What to use for graphing sounds of instruments
For my physics EEI I am wanting to look at sound frequencies. What I plan to do is to get a guitar and play a note, lets say a "c natural". Then I want to play a "c sharp" and then compare the two notes. I want to be able to find the amount "beats" over a duration of say 1-2 seconds and then compare to something that is more pleasant sounding. ie. a "c" and a "g" . And find how many beats there are over 1-2 seconds. I want to find if more beats are better or less beats.
Now my problem is that I have a program, Datastudio which can pick up me playing my instrument through my computers microphone. However I can not figure how to use the program or if there is a program function that allows me to go | F2 - F1 | = Fb F being frequency, 2 and 1 being different notes of different frequencies.
Any other programs out there that can do what I am requiring please tell me about. But if there is a way to work Datastudio please help, I can't work it out.

You don't need any thing but a calculator and this chart:
just subtract the frequencies of the two notes .... it's not so much the number of beats but the integer ratios. Also, the western tempered scale fudges all the notes such that they don't quite match up anyway, compare it with "Just Intonation".
But you may be interested in an audio spectrum analyzer. I don't remember if Audacity has one, but a quick search might find some free candidates.
