Hal, What I am finding is that all the wav to midi converters are extremely limited in accuracy. They are very blunt instruments, useful in only limited circumstances. Because of the very things you mentioned, I don't expect much. The reason I even am looking into this is that I would love to have a tool that would translate wav files into midi notes (not sounds or samples). I just want the notation and timings. I think one large stumbling block is that I want micro-tonal translation. Not just whole and half steps (black and white keys). Ultimately, I would hope to be able to directly record the output from fractint to the PC speaker as a wav file and then translate that through a software solution into midi notation. Of course, I have already done that in a much more convoluted process 20+ years ago. At that time, I studied the midi specifications and wrote my own program (I believe in FoxPro) to convert the data contained in the sound.txt file produced by fractint into midi files. It was a monumental project for a total midi novice. The best example is probably "Inhale" http://tinyurl.com/ppyjwj5. It was made using a fractint-produced sound.txt file(s) and is unaltered as to timings and rhythm and notation. Of course, in midi you have/get to determine the instruments, relative volume, etc. But all the astonishing shifts in mood, etc occurred in the fractint output. I didn't dice and splice...it is all linear production. Unfortunately, all my programs and much of the work product was lost in a catastrophic disk failure, and following unsuccessful attempts at restoring from tape backups that didn't work, I lost momentum on the project, and abandoned the midi pursuit in favor of more pure methods of obtaining audio fractals. But it was a fun and productive project that I would like to resurrect without having to go through all the learning again...time has taken it's toll on my energy for doing that again.

Bill, You said:
A couple [of .wav to .mid converters] I have found so far... I'm pleased to be proven wrong!
However a close reading of the description of the 2nd program you listed: http://amazingmidi.software.informer.com/
indicates that its ability is quite constrained. They say:
"Currently, automatic music transcription has no substantial solution in general, but with some restrictions of the domain [this software operates in,] it can be both possible and useful."
Good find, Bill!

Bill, You asked:
Does anyone know of a good, preferably free, .wav to .mid converter for Windows? There is no algorithmic way to perform this task -- hence there can be no program to convert .wav to .mid.
The crux of the matter is the extreme condensation of the .mid specification -- it is basically the name of an instrument; a specification of the note to be played and its duration. Multiple instruments and notes can be specified to be sounded simultaneously.
In contrast, .wav files are audio sound waveforms. The waveforms of multiple simultaneously-played sounds are added together resulting in their sum -- effectively representing a (digitally encoded) particular air pressure at any one instant in time in the .wav file.
Audio sound waveforms can be converted between different audio sound waveform encodings, like .mp3 .wav and .ogg . Here are a few hundred more: http://fileinfo.com/filetypes/audio
However, converting from .mid to .wav is easy. At every moment, in however fine a time slice is being used, each instrument's note's sound pressure is added to every other note playing at that moment. This sound pressure (or amplitude) is the value stored in the .wav file for that moment in time. The air pressures must be represented 10's of thousands of times a second in order to be able to encode and play back "faithful" sounds.
Sorry for the hurried, off-the-cuff description...
