Music Recognition Pro
-
Version
3.0
WAVE to MIDI, MP3 to MIDI, CD to MID : Recorded music
can be converted into score!
Maybe you have a particular sound file(wave or mp3
files) that you wish to transfer into your 7650 or
other mobile telephone through infrared, because the
file size is too larger.
Now you can use WIDI to reduce the size of .wav .mp3
files before transferring! Just try it!
WIDI is designed to automate transcribing of music.
That means that the task of retrieving music score
from an audio record, which is usually accomplished by
a hard work of a professional musicians,is about to be
solvable by a computer.
You can take you favorite audio record and convert it
into notes.
WIDI allows both monophonic and polyphonic conversion.
You can even record your own voice and then convert it
into score! Then you can change it in any way, print,
reassign instruments, cut off some notes, add new,
etc. with your favorite MIDI Editor (such as CakeWalk).
Software Features:
First it produces some kind of spectra-like data, this
is called further the "WAVE->Pitch" conversion. Now
there are two different algorithms implementing this
step, each of them has its own advantages and
disadvantages.
Then it multiplies that spectral data by coefficients
of "Equalizer", making some pitches louder and some
pitches more quiet (This is only for Widi for Windows
version).
The third step is an actual retrieval of notes from
the spectra, it is called "Pitch->MIDI" process and
there are also two algorithms making that.
The final step is producing the MIDI file structure,
and you can choose some attributes of the output MIDI
file.
Nowadays investigations of more complex schemes are
taking place, it seems that they will allow to
differentiate musical instruments and make fewer
errors.
