There is a program that does an so so job of sound file to midi conversion ... see intelliscore.net site ... A friend has used it and says it work for some kinds of sound sources, I have not tried it. But this is a very hard problem and full of lots of rough edges On 06/10/2015 04:40 PM, Hal Lane wrote:
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...
