no. the two are different. Wave files are the equivalent of digital
audio-tape. MIDI files (at it's most basic) only contain a command to turn
a note on, a loudness parameter, a pitch parameter, and a final command to
turn the note off. this is somewhat confusing tho. allow an analogy.

if i spoke this sentence into a microphone and recorded it, you could hear
ME saying it. as it is, you can only read my sentence on your computer
screen. you don't even have the same fonts i do, cuz i'm using telnet to
write this. but the words are there.

this is like the difference between WAV & MIDI. WAV contains sound. MIDI
doesn't. midi sends information to something, somewhere in your computer
that DOES make sound. probably your soundblaster card. the SoundCard has
tiny little WAV files on it, which are triggered by the MIDI information.
more complicated midi info allows the composer to send other info into
your card too, like pitch bending information for instance.

the way most people convert WAV to MIDI is to learn the melody in the WAV
and play it into a MIDI sequencer. which is fine if it's a bass guitar or
a piano, both of which are sounds your SoundCard has, but if its Darth
Vader saying "you are in really deep trouble", forget it.

well, that's probably a way longer answer than you needed. hope i didn't
miss the point of what you were asking.
