|Hello out there.|
I just want to know if there is a program which converts the music of a MP3-file into notes. I would for example click on "Keith Jarret - Köln Concert" and the program would print out the notes so that I could play it on the PC.
Does anybody know if something like this already exists?

|No seriously, I just want to know if something like this exists.|
My aim is not to skip the process of transcribing, I want to write such a program. It is for a competition.

|sorry...just being silly...I heard talk a few years ago abot someone working on something like that...I guess it would have to be some sort of pitch ot midi converter deal..but how could/would it discriminate and/or decipher all the pitches? Any percusion part, bell or whistle, would have pitch...Anyway, I've not heard of one yet|

I was working on just such a thing a few weeks ago. I started with the simplest possible recording. My keyboard recorded playing C major scale with half second notes and space between them. It was unbelievable how tricky it still was. I tried out several different methods: straight up FFT, autocorrelation, HPS, etc, but I was unable to find one method that stood head and shoulders above the others. What I ended up doing was trying all the methods on each window of sound and having them vote (this is actually how nuclear reactors are controlled, 3 different computers, each running different software, and they vote on things. that way if one fails, you still have two others with different hardware and software). I was still only able to get like 80% accuracy. I'd be curious to hear if you find better methods. Mine is hardly state-of-the art, and I realize lots of doctoral theses out there probably describe how to do it better, but I ran out of steam.. Let me know how it goes!

|There are several wav to midi converters out there. You would have to take your mp3 and turn it into a wav file (easy enough). However, these days I bet some of those same wav to midi converters will work with mp3 as well. Just do a web search on "wav to midi"|
