mp3 to midi
 

Does anyone know any good (preferably free) programs to convert mp3 files to midi?

Er, it can't really be done Russ.
Midi files are made up of actual notation data that is sent to a midi instrument (usually a sound card in your PC) to tell it what to play and an mp3 is sound wave data.
A bit of a difference.

Silly Roger, yes it can! The one they recommend here is a bit costly, I don't really want to pay that much for something I'll only use once or twice.

I don't see how a program would be able to tell the difference between a harpsichord or a piano but good luck to you, you'll need it. :D

Mp3 (as well as other waveform sound formats) and MIDI are in principle different forms of sound representation. MIDI contains commands, and MP3 is compressed waveform. That's why the task of MP3 to MIDI conversion is much more difficult than, say MP3 to Wave or others.
Here I found one of the most clear description of this process I have seen:

There isnt really a way to turn an mp3 to Midi.
Even as Wav you won't be able to sperate the instruments and get the info for each note.
Your best bet is to play it again yourself in something such as Reason, and then export the instrument notes as midi.

Er, doesn't that go the other way round ? :erm:

It's been a while since I looked into this, but the last I heard, it was possible to do it, but the results were inaccurate. It was adequate for Pop and Rock music (by Pop, I mean most modern music) which have a relatively limited frequency range. It didn't work at all for classical (or orchestral) music.

Basically the process works in a similar way to speech recognition, but is an order of magnitude more complicated.
