Topic: Piano audio recordings to midi converter

I see a lot of audio to midi converters on the internet but they don't work well for piano or other polyphonic instruments recordings.

Is there a good piano audio recordings to midi converter? I have some piano audio recordings that i want to listen with pianoteq sounds, please help me.

Re: Piano audio recordings to midi converter

The best polyphonic audio detection out there is Melodyne. Nothing else tops it. However depending on material, Melodyne can be hit and miss. There's no silver bullet for this.

Hard work and guts!

Re: Piano audio recordings to midi converter

I concur with Mr. Dragon:

Melodyne can certainly be hit-or-miss, especially if a lot of sustain pedal is used in the original piano performance.  Melodyne simply does not know how to handle sustained notes, especially if there is a lot of pedal work at hand.

If more than a modest amount of rubato is present in the original piano audio to be converted, any audio-to-midi converter may confuse the correct placement of rhythm and bar lines.

In addition, reverb tends to wreak havoc with audio-to-midi conversion.

Cheers,

Joe

Thank you for all the answers.
Is there a service to convert piano recordings to midi files? Because on Youtube some pianists sell piano midi files (only 1 dolar per midi file) but usually they don't take requests.

Re: Piano audio recordings to midi converter

The only service would be paying someone with perfect pitch to do a transcription

Hard work and guts!

Thank you! I Can’t find a person who do that.

Re: Piano audio recordings to midi converter

Before you do that you might give Transcribe! a try.

30-day demo, and *much* cheaper than Melodyne (you would need the top-of-the-range Studio edition). I have not used it, but the reviews make a trial irresistible. (Ars longa, vita brevis, et cetera).

Re: Piano audio recordings to midi converter

I use AnthemScore ( https://www.lunaverus.com/ ). Is not expensive, has free trial (limited). It gives you more or less the correct notes and rhythm, it loads the
transcription directly into Musecore (if you have that, it is free). At least it quickly gives you the basis/starting point. After that I make something playable using Transcribe. It speeds up transcription process a lot, no need for absolute pitch either, every amature can do it.  I just tried with this video someone posted some time ago (Body and Soul Nellie McKay, I dont recall where, sorry, it indeed has a very nice pianoteq like  piano sound):https://www.youtube.com/watch?v=iXZvWJx0RTs , the result is actually already quite OK, it just takes 5 minutes. With lots of sustain it is not so good off course and unfortunately..

One of the best tools for converting piano audio to midi is Eldoraudio's Piano Audio to MIDI Converter.
It is extremely accurate and easy to use. I hope that helps.

I tried Magenta a few years ago, but it needed a lot of corrections. I just tested the same tracks on Eldoraudio. It's excellent, it even find the pedals movement. Thanks for the link.

Transcribe! is an audio and mp4 video slowdown/looping program, it does not convert audio to midi by itself. I have used it over 20+ years. You loop an audio in small chunks and write the notes down yourself.

New kid on the block of audio-to-MIDI translation, and one that requires nothing to install.

Where do I find a list of all posts I upvoted? :(

Basicpitch does not detect any pedals, poor detection. File cannot be listened to directly, unlike Eldoraudio's. Test performed using the same file (1966 recording). Eldoraudio is very impressive before any correction.

I have always been disappointed with audio to midi converters , specially when sustain is down , but I have to admit after a few tries Eldoraudio is quite good . Of course it still needs some corrections , but may well be the best one I have tried so far .

Just to let you know the open-source tool I created, it's actually "the latest AI model" published in 2024: https://github.com/Yujia-Yan/Transkun .

Wow, this is great. Thanks Daniel.

Re: Piano audio recordings to midi converter

I came across this github project, https://github.com/HemantKArya/Melodfy , that does a decent job on the notes but does tend to split longer notes into several shorter ones, so you have to go through and do some note joins.

Re: Piano audio recordings to midi converter

I think I might find something like this useful for transcribing something that sounds complicated to me that I struggle to figure out. Something like the actual notes being played by Oscar Peterson or a few others that have blistering speed, or a few of the various church musicians who come up with lush chords that are a little out of my wheelhouse that I'd like to get more of a handle on. It might not even be full works, just little bits and pieces that are not so easy to pick out by ear.

Just a wonderful working Yujia.

I put a Rachmaninoff prelude op 23 No2 in your great piece of software, and it did a terrific job.

Congratulations, it is just gorgeous.

And of course, Pianoteq did a tremendous job for reconstructing the midi file as perfect as the audio file...it is so impressive.

Congratulations too, Pianoteq team.

Best wishes.

Re: Piano audio recordings to midi converter

Still can't believe how far these detection software have come.
For now I'm still using eldoraudio for these, since it works pretty well for the kind of audios I test it with.
One of the interesting things of it is the use of the pedals, both damper and una corda.

Original: https://www.youtube.com/watch?v=CvUTTAw8Dew

Recording of the midi file played with a Pianoteq K2 preset: https://www.mediafire.com/file/h057exaq....flac/file

The midi itself: https://www.mediafire.com/file/7m7acl1d...y.mid/file

I'll check the rest of the tools people were sharing here later and put some example audios for these too.

Re: Piano audio recordings to midi converter

MbcCovers2 nice idea, I will post here the audio and the midi files of Rachmaninoff prelude op 23 no2.

You are right, it's impressive how this technology know when pedals (sustains, una corda) are down or up.

Check this out how great the software of Yujia did.

That's pretty

Re: Piano audio recordings to midi converter

Maybe try this

You can even try the sample mp3s at the bottom

It uses an AI model https://huggingface.co/Genius-Society/piano_trans

Re: Piano audio recordings to midi converter

Are you using AI as much as it is using you? There is another AI that is always watching, learning... Why?

How did you manage to install this tool?
I am not realy good with programming stuff, but I asked a well versed programmer (doing things like that for a living) to inmstall this from github. He did not succeed.
Any help from your side?

Thanks in advance

Re: Piano audio recordings to midi converter

I just used my s/w, nothing for you to install

Downloaded the mp3, turned to midi

Actually I am not a programmer either, my Linux knowledge is very limited. I did installation following the problems when they were appearing.

The problem every system has some missing packs and others different packs installed.

First I installed the pip (python) software. When I try to install "pip3 install transkun" I got the first problem. It was missing some packs that I don't remember now, but I just ask the A.I. (I just wrote in my mozilla that it has an A.I integration, like chrome has) ,(my system is Debian 13) and follow the instruction.

I follow all the steps of the missing packs and after almost 10 gig of download (I needed to download the A.I. components) I just need to activate the VENV python environments (that was for me the principal point).
The program ran smoothly, but I couldn't run with my gpu mode, only with my cpu mode (more slowly).

I hope these steps give you some ideia.

Thank you. Yes this might help my son to overcome the problems (Same approach by the way - missing packets, missing software, AI helped further. But not up to a successfull end. Yet!) With your input that might change. Best Regards
