Audio-to-MIDI Conversion
By John A. Tuttle

Hi All,  I found a program called AmazingMIDI which is advertised as
a 'Polyphonic Music Transcriber'.  The unregistered version allows you
to create a maximum file size of 30 seconds.  To use the program you
must first create a WAV file from the original audio file.

This program is rather complex and has numerous filtering and timing
options.  I have tried to convert a number old audio files of me
playing my Lauter upright.  The output MIDI file has been only sketchy
at best.  I think one problem is that you must first create a sample
audio file which the program uses to interpret the audio file.  Another
problem is that MIDI is 'on the beat', whereas a live recording is
seldom in perfect time.  So even though you end up with a MIDI file,
none of the notes fall on the measure lines, except by accident.

A quick search at using the keyword "AmazingMIDI"
yielded some 3000+ hits.  It appears that creating MIDI files out
of WAV files has come a long way in the last year.
