WAV file conversion

I guess this is a non starter, but I'll ask the question anyway - does anyone know a way to to convert .WAV files to .MID files?

As far as I know, there are no programs currently that can do that type of conversion reliably, due to the many factors involved. I have vaguely heard that efforts to do so work even more dismally than OCR conversions.

For the foreseeable future, I think the best bet is to program in the song or item in through use of a midi-instrument. You may also be able to find a midi rendition of the music on the Web.

Peter,
Check out the site: www.audioworks.com. There are two programs that might be of interest to you: Sound2Midi, and Wav2Mid. I downloaded the trial version of Sound2Midi and exercised it quite a bit. I played trumpet into the sound card card (computer microphone) and viewed the notated results. Not bad, but not perfect. This program is for monophonic sound, but am not sure about wav2mid. Give it a look.

You could also try (shareware, 20 USD) AKoff Composer

The 1.03 version is just out, didn't try it (I downloaded 1.0b 98.9 and never had time to try) but if it work as promised, it's worth the price.

Due to huge mathematic calculation or signal analysis, wav to midi conversion is rare. This is much more complicated than OCR, since any instrument's sound is made by additional waves at different frequencies, that can be common when more than one sound (or instrument) appear. In fact, it is amazing that the human brains can recognize a pianissimo piccolo in a full orchestra...

It's no good trying to convert WAV to MIDI, as there isn't a program capable of recognising the different instruments within the piece being converted.
I have tried all of the above without success, your best bet is to find an existing midi file on the net.
However if your wav files contain notes from only one instrument then you may have more luck.
If you do solve this problem there are hundreds of people on the net who would like to hear from you.
Good luck !

Just a note about Wav2Mid. I tried it and it has nothing to do with converting what is actually in the .wav file to midi format. It just uses it somehow to generate a totally different (and very strange sounding) midi file.

I downloaded yesterday the Digital Ear demo.
I was amazed with its capabilities.
No other program (wav2midi, autoscore)could really
recognize any instrument like this one.
I will definetly register.

Sound2Midi, Wav2Mid, Autoscore, and Digital Ear are all intended for use with monophonic music - one note at a time. If your wav files contain many notes at once such as chords (most do), then these programs would be of no use.

There is a program called Intelliscore that creates midi files from polyphonic wav files. The results aren't perfect, but it's still quicker than transcribing by hand.

You can download a demo from http://www.intelliscore.net.

'....that actually works'

Do you need to qualify that.
Will Digital Ear transcribe a midi file of Glenn Miller's big band playing 'In the Mood' with all the saxes, brass and rhythm on separate tracks or will it only transcribe a single voice or perhaps 4 voices from guitar/piano chords.

I've spent a lot of time pursuing the claims of wav to mid software vendors and have found them to be exaggerated to say the least.
Digital Ear, Amazing Midi and Intelliscore come to mind.
Even as single voice transcribers it's faster and more accurate to rely on your ear and your note entry skills than fiddling with parameters and editing until you get a less than satisfactory result with any of these.

I believe that Digital Ear is by far the best of all
similar programs.

The reason for that is that actually WORKS!

I've found that the Russian one (URL a couple messages earlier) works as well as any of the others... and it's completely free.

Digital Ear is probably the worst, since it relies on your synth being capable of a one-octave pitch-bend range -- completely at odds with the General Midi spec, and therefore not even usable with the majority of GM-compatible sound cards.

It is completely wrong that it relies on the octave pitch
bend range. It is user adjustable, just see the settings.

I have used many of the above packages so I can convert cd samples recorded into wav files into ringtones for nokia phones. Widi recognition system 2.5 is ok but as with all of them they don't like high pitch sounds and multiple instruments.

If any one knows how to convert the pitch of a wav file or midi file please e-mail me.

You can get a Real-Audio encoder called Real Producer from their website at http://www.real.com/ -- there used to be a free version available (probably still is, you might have to dig through their site), without the bells and whistles, and seemed to do the job just fine... if /any/ "real" audio can be called "fine"...

Hello everyone,
I am simply looking for a way to convert
a wav file to a midi file.
Wav files always wind up too big!

Somebody figured out how to make the files.

I am sure it can be done, we have remote
satellites that can do all kinds of wild stuff.

Does anyone know of a help forum where I
might find a tip, rather than everyone just saying
" It can't be done "

Perhaps a more precise way of phrasing it would be to say "it /hasn't/ yet been done, and it is unlikely to be done in the foreseeable future."

I don't think anyone was trying to make fun of anyone by using the text-to-jpeg analogy. It's actually a very good analogy for the situation of converting a complex sound recording (wav, mp3, etc.) into a representative series of commands (midi).

That being said, there are programs that purport to do this, with varying degrees of success. Check out Audio2Midi by Alexey Egorov, it's a free download and in my opinion anywhere as competent as some very much pricier products. Even so, I consider it little more than an interesting toy.

Re: WAV file conversion

Isn't the text-to-JPEG analogy backwards? The text, being a high-level description of the scene, seems to me analogous to a MIDI file, while a JPEG, being a complex realization of the scene, is more like a WAV file.

In fact I imagine it would be relatively easy to construct a program that could produce a JPEG file from a (highly formulaic) text description plus an appropriate library of clip art (MIDI->WAV). What would be difficult would be a program that could take an arbitrary JPEG file and produce a concise description of its contents in words (WAV->MIDI).

Re: WAV file conversion

Reply #31 –
You are right, Grant. My word-to-JPEG analogy IS backwards.

In fact, I believe it would be reasonably possible for sentence-parsing software to analyze my sentence about the sunset, go to an image library for seashore, sunset, seagull, and surfers, and put something together!

We are not trying to make fun of the person who asked the original question. Indeed, there are existing programs that accept WAV as input, think about it, and give MIDI as output. But in no sense is the WAV being "converted" to MIDI. The inadequate quality of output, when re-output as sound, is the problem.

More to the point, I gather that the main reason why consumers would want to convert WAV to MIDI, which could then be formatted as sheet music, is to learn how to play someone else's (copyrighted) recording. I believe that faster information transfer rates are technologically close enough that conversion of WAV to MIDI, merely to save space or bandwidth, is a waste of programming effort.

Folks,

Maybe this wav-to-midi subject; differences between a wav and midi and why a wav couldn't yet have been successfully converted to midi etc. can be done as a web article or a faq.

I have some concrete data on the subject:

* A simple nwc/midi file (only a C chord w. piano patch),
* WAV file recorded from it,
* MIDI file said_to_have_been converted from the WAV,

if would be of help.

I think the Scripto will be a proper host for such an article.

Regards.

PS: Apologies to John; I didn't intend to offend him anyway.

yo,yo,yo,yo! If anyone still reads these things.... I tell you that wav-midi conversion can be done. Most programs suck and only do the mono files, but AKoff's composer really does work properly. I converted a wav file that completly screwed up on every other program on AKoff, and I was quite pleased with the results. I recommend that you people try it out. It's the only good one there is. You can't save on the demo, but if you can chuck up $29, you can save all you want. and this one doesn't place those stupid 15 second limits on your conversions, either.

Try it!!! :-)
