Anyone knows where I can get a free wav to midi conversion program (not a demo but free).
in theory, some of them can really convert wav to midi
but the quality is...... really..... awful
so, i suggest you to wait for that specific midi, but not convert the wav file to midi
Forget about converting WAV to MIDI. It can not be done appropriately.
Thanks for the info. I just like to try converting the wav to midi, but hearing what you guys said I guess I shouldn't be bothered.
We have already bothered for you.
>Forget about converting WAV to MIDI. It can not be done appropriately.
Well, depending on the piece, ie how many parts it has and so forth, and if it's monophonic, you could actually do some nice things, capturing any nice passages and hopefully being able to ear any chords in the piece. Or you can slow it down and pick it out yourself. =)
Rubbish! Where on earth do you get all these silly ideas from?
If it has more than one 'part', then it is, by definition a polyphonic file. If it has more than one note playing at the same time, likewise.
It is possible to convert a monophonic file to midi but impossible to convert a polyphonic one.
>but impossible to convert a polyphonic one.
It is not impossible. Prior knowledge of the synth's emphasis of various harmonics to create realistic sounding instrument simulations mean we can deterministically extract notes from chords using high-frequency sampling and low-frequency pattern matching.
And of course it is polyphonic, sorry for being vague.
There he goes again. What the hell do you mean?
YES IT IS!!!!!
How many times and how many people do you need to tell you this before you give up on the idea?
Stuff and nonsense!
We're talking about a conversion to midi here. I'm not disputing that it is possible to extract the notes of a chord (although it's far from an exact science) and there are softwares around which can do this already. However, that's only part of the problem.
In the real world, you are not going to have just a single chord, played on a single instrument to contend with. You will have a number of notes (some even at the same pitch) occuring at the same instant in time - how do you propose to separate all these out into individual midi channels and identify the various instruments which are being played at that moment?
You are so hung up on this idea, you have lost sight of the basic fact of midi being a means of storing performance information - no more, no less. In itself, midi is not music!
You have the whole process back to front. You use midi to create music, not music to create midi.
It is possible!
It's not 100%, but however.
If you need perhaps only the melody!
Try it with Celemony Melodyne.
It's not free, but I think they have a demo.
It is not possible!
As for Melodyne, I don't know what planet you live on (seems like cloud-cuckoo land to me) but it knows absolutely nothing about midi. You didn't even properly read the link which you gave.
From their own website:
Melodyne is a programme that allows a completely new approach to the handling of audio material. It analyzes the pitch and time of monophonic audio files (from, for example, singers, wind or string instruments) and offers the opportunity to change whole melodies in a way only previously possible at MIDI-Level.
u can go to www.download.com and search for wav to midi converter
i hope u find whatever u lokin for
I have tried some of the demos of wav to midi and they are like the vocal eliminator software, they do "work" but only if you redefine your defination of "work" anyone looking for an easy way to convert that great CD track to midi better get programming.
ok ok I get the ideal, no need to argue over this matter...
Anyone who really thinks it is possible to convert a polyphonic .wav file to midi, is welcome to take up my challenge here;
i think it could be possible, if we had the technology, and we probably do.
get something to recognize the wavelengths and match them to an exact pitch as well as the exact instrument. of course having different instruments would create interference but then the same interference could be created in the midi.
But, currently, we don't have the technology. Let's leave it at that for right now.
snot possible, sorry
