Can you recommend a good MP3 to sheet music converter program that is accurate?

• Apr 9, 2023 - 17:18

Hi again everyone. I apologize for asking lots of questions on the forum, but you all have helped me a LOT.

I am struggling to find a good program that will listen to an MP3 recording of a song, and convert it to reasonably accurate sheet music via AI. I've tried AnthemScore, AudioScore and one other, and they all are just not too accurate. They really struggle if there is more than one instrument, and mostly lose timing/tempo, with failure to properly identify measure bar lines (4/4, 6/8 breaks, etc.). The notes are frequently inserted only as 1/8th or 1/16th notes separated by rests, and the heck with beat.

What is the "best" MP3 to sheet music converter program out there that you all have used? I am willing of course to pay for it, if it is reasonably priced. Thanks so much in advance.

Thanks. I read this earlier today and tried the first 3 programs on the page. Unfortunately, as you suspected, the result was not great. I tried them out on an intermediate piano MP3 recording, and none of the three sheet music outputs were reasonably usable without a lot of editing. I can understand the challenge, but ...

Have any MuseScore users ever used an MP3 to sheet music converter that they liked? If so, I'd be grateful for your recommendation. Thanks

I am looking for a program that will produce readable sheet music from an MP3 recording. I did not get the impression that Melodyne produces sheet music from its MIDI files. Apparently, MuseScore can, but I will need to investigate this more before I can reach a conclusion. I checked Melodyne and it is expensive ($700 for the studio version). I am not ready to spend that much, so ...

I spent the better part of yesterday trying out many of the converter programs. Including Basic Pitch, Transcriber, and Amazing Midi. Basic Pitch produced the closest sounding midi. But the notation was unusable, Completely. Even though playback was not too bad. It seems to me that these programs are meant to produce a file that is used in a DAW, and can be manipulated there. Not in notation software.

For testing, I used a simple four part fugue that I wrote for piano. The wav. file was clean and without any effects.

Transcriber produces a midi but you can't save or download it.

Amazing midi hasn't been supported since 2003. There are no instructions on how to use it.

Thank you for your kind efforts in checking those programs out. It is most disappointing that they convert a music file into a spectrogram, then identify on the spectrogram those areas that appear to be 1st harmonic notes, and write them down as sheet music, only to lose most all of the timing/tempo/beat. I can understand it, but ...

I will keep looking. Someday, one of these programs will break out and really work. In the meantime, I will restrict myself to less complex pieces.

We are a very long ways away from this being viable AI technology. Check back in a decade or two. Right now, human ears are 10000000 times better. Myabe each year you can knock a zero off that...

Marc: Thanks. You are right I guess. The original software that started this thread is called "Anthemscore". It produced a reasonable score of sheet music out of an MP3 recording, but its timing/beat was non-existent and I would have had to redo the entire song manually, changing all the 1/16th notes to 1/8 or 1/4 notes, moving notes extensively to match 4/4 time, etc. I can listen to a song and write each of the notes manually, and I do that to some extent with every song I put onto MuseScore (over 55 to date), but at my age, ... it is getting so tiring!

Marc: I agree with you. Fortunately, I am quite good at ear training. I have over 50 songs now on MuseScore and all of them have ratings of 4.5 to 5, in part because I can hear and record notes just fine and the songs reflect it. As an example, listen to this particular song from Hans Zimmer I did: All the notes I identified purely by ear (no sheet music was available).

I thought help from a computer to convert MP3 recordings to a good starting set of sheet music would be worthy to buy. I now see that such a program does not yet exist, so it is back to listening only.

Hello, how much would you charge to convert an mp3 I wrote in to a score? I wrote it in college using Sibelius and then converted it to an audio file to upload to Youtube but then I lost the MIDI file and I haven't been able to replicate it yet.

Two ideas to try:

  1. Try Frettable. Free version available, then subscription with longer length.
  2. Run it through an equalizer first. This way you can reduce the clutter and pick out one instrument at a time.
  3. If a song is available in multiple covers, doing the extraction from multiples may help.

Instruments are picked out by lookng at the harmonic structure. This gets really messy in an ensemble. Some instruments are a lot worse, I suspect.

  • Electric guitar with distortion.
  • Drums. Picking up the beat is easy, but picking which drum can be tricky.
  • Instruments that play with pitch bend, wah-wah

As a workflow you may need to bring it into a DAW that allows you to edit a "piano roll" midi and then you can move notes from one instrument to another. Check your work by having the mp3 as a track, then play it on one ear, and your corrected midi in the other ear.

Given how difficult a task this is even for someone who is musical, I'm amazed it works at all.


You can try PianoConvert, which is currently the most accurate software for transcribing polyphonic solo piano audio into scores and MIDI files (works with YouTube link or audio file):

I've heard that they're going to extend use to instruments other than the piano soon, but I don't know more than that
