Topic: Midi to MP3

Maybe it was commented a lot of time ago in this forum, but I want to rise this question.

Who knows a software that help to get the music notes from a MP3 ?

I remamber I tesded one about 2 years ago, and despite the good demosntrations in the site, in practice it was a scam.

The software was claimed as able to get midi from mp3 even for 3 or 4 instruments combined.  But I tested using a very clean solo piano music from a CD, and the software get much more mistakes than right notes.


I want to know if there is already someting decent available.

Re: Midi to MP3

This was just mentioned in another forum:
http://www.neuratron.com/audioscore.htm

but I have no idea how well it works.  I'm eager to try this out - I was looking for something to do this recently and didn't find much at all.

This comparison page looks useful:

EDIT: P.S  I don't think you could ever be accused of making too many on-topic posts.  ;^)

This is the best right now to get inside polyphonic audio

Thank you Skip
Thank you Olepro

These comparisons prove that technology in thi use it's very limited.
Even Fur Elise got a lot of mistakes when converted.  Disapointing...
I still  see almost no use of such softwares. 

A highly trained great musical ear is light years ahead of that. The human brain, even for who have no absolute ears, can separate de sound much better than actual algorithms, while softwares seems like just try to see the pitch, but cannot separate the sounds when combined.

Intelliscore times is the most expensive, and the worst in the comparisom test.

I noticed that the tests in the Intelliscore website had a very overly distint sound notes for the mp3, sounding a bit unnatural, almost like was modified to make the notes extremelly easy to the algorithm take the midi.

Re: Midi to MP3

Hey, I was imagining if one day pianoteq will have something similar.

You would load a piano mp3 or wave and pianoteq would analyze it, and not only gave a midi but automaticly choose a preset model, adjust the piano variances and sound variances as mics placement, gain, and reverb (with room configuration in details.)

Ok, ok,   I'm almost asking Modartt to make magic... 
This was a bit too far  ;-)

Re: Midi to MP3

Well...

Some few aspects could already be analized for replication with actual tecnology.

The unison for each note could be get automatically from a recording, by measure the pitch of strings's vibration. Missing notes (not played in the music) would be extrapolated neighbor notes aproximation.

Perhaps hammer hardness could be analized too, by how much brilliance each velocity have,  but would require that the performance have a quite some "ups & downs" in dynamic terms. 

Well... would be a start...

I sometimes use the Chord Analyzer that was integrated into Band-in-a-Box a few years ago. Before guessing the chords, it of course tries to extract the notes. If the polyphony is dense, you can't expect good results, as with all similar tools: there are physical limitations, regardless of technological advances!

However, it helps me indentifying jazz basslines - my old ears are more and more deficient at low frequencies :-(

Re: Midi to MP3

Iaoranaemaeva,  sorry disagree.

I think the limits of mathematic of acoustic it's not the case.

Our brain, when good and used to music, can listen to a good recording with a lewt's say 2 people talking and 3 different instruments, and if we pay attention we can separate the sound of each person and instrument.

Even we have no absolute ears, we can think:  "Hey, that noise it's not a music, it's a someone speaking, it did not count."   Softwares don't do yet.

It's similar to image analyze. We see a photo and imediately we separate foreground objects and textures, from background, and identify each object.  Computer sofwares still fight to fast sellect a object with few erros even for a hand-assisted tool.

No digital algoryth match our brain algorythms.
