Is there any software available which will convert an audio file such as an MP3 into a score, a midi sequence, or some other representation of the pitch, order, and timing of the notes?

Recommend closing: naive and ambiguous, not to mention the conflation of music with a digital compression algorithm. –  Carl Witthoft Nov 19 '13 at 12:37
@CarlWitthoft That's not a good reason for closing. Why don't you explain in an answer why this wouldn't work? –  American Luke Nov 19 '13 at 14:31
Yes, it could be improved and yes it is ambiguous. However, a question should not be closed for a lack of knowledge in the area. –  American Luke Nov 19 '13 at 18:27
Carl, I respectfully submit to you that we can safely assume when some one uses the word "note" in the context of music it should be interpreted as a notation for both pitch, duration, and touch (e.g. tremolo, pizzicato, etc). –  filzilla Nov 19 '13 at 20:16

There is software that can analyse audio recordings, and extract a score or a MIDI sequence.

Audioscore by Neuratron is one. I have not tried it, so this is not a recommendation.

I have been looking for a piece of software like that for ages due to the sheer novelty of it. Thank you very much! –  Tim Hargreaves Nov 19 '13 at 17:56
Neuratron also make PhotoScore, the equivalent for reading printed music. When it works (notably on a page that originated in Finale, Sibelius etc.) it can work well. When it doesn't, forget it. Correcting errors takes longer than starting over manually. But the program isn't rubbish. Now, some strong words. AudioScore IS rubbish. It's the nearest to complete misrepresentation I've ever come across in a commercial program. I've stated this before in various places, and never been seriously contradicted (which is very rare on the Internet:-) –  Laurence Payne Feb 25 at 15:02

A.S. - audio signal transcription is not a perfect science. Like image recognition, no one can claim to have an algorithm which always works. Ambiguity may not be handled by software with 100% success.

The latest version of Ableton Live has built-in pitch recognition, the user manual should already cover that in detail. The algorithm is quite precise.

What I prefer, is WIDI Recognition System. Not only it will transcribe the audio with a fairly decent (and highly customizable) algorithm, but it will also project all the notes on a frequency spectrum (screenshot below), not to mention the support for separate tracks recognition (probably the hardest thing for a software to do): unless the original signal is in bad shape, is really difficult to fail in a perfect transcription with this approach. Where the software fails, and your ear is not trained, the eye will spot the error immediatelly.

I found WIDI Recognition System to present the most comprehensive set of tools for transcription.
