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

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.
