WAVE to MIDI, MP3
to MIDI, CD
to MID: Recorded music can be converted into
score!
Quick Start: How to convert MP3, Wave to MIDI - Shows
steps
A sample file converted by
WIDI: Name:
Badinerie - J.S.Bach
MP3 File: Click
Here Size: 478K
Midi File: Click
Here Size: 12K
Now new WIDI 3.0 can work
both in real-time and off-line mode.
In off-line mode WIDI creates MIDI sequences from input
files (like mp3s or audio CD tracks). This gives you numerous
possibilities:
* turn a melody into MIDI format
for further editing
* upload a melody to your web page
* use a melody in your cell phone
* playback it on any MIDI instrument for training
* use it in any other MIDI editor (some are able to
print MIDI files as written music)
* make a preview of your mp3 collection (saves traffic
on your web site)
WIDI also works in real-time,
instantly converting music at the microphone or line
input of your computer into a MIDI sequence. Think of
this mode as a powerful music processor which allows
some non-MIDI instrument (like a guitar) to sound as
a violin or a piano or whatever instrument you've got
in your MIDI synthesizer.
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).

"Midi,
wave, mp3 to polyphonic ringtone composition and
converting software. It can convert MIDI, wave,
mp3 to mobile phone ringtone. You can write your
own music in Mobile Music Polyphonic and save to
polyphonic ringtone format file. It can save your
music into standard midi, SP midi and SMAF format
(*.mmf) file. Convert mid to mmf, mmf to mid, standard
midi to sp midi, wave to mmf, mp3 to mmf and mp3
to wave file." |

New in Version 2.70:
New recognition algorithm was released.
New features - CD grabber and Wave Recorder, as well
as ability to use ACM-compressed WAVEs. Some important
bugs were fixed.
New in Version 2.6:
MP3 support added. Possibility to
use intermediate files for faster calculations added.
Windows NT 4.0 and Windows 2000 are supported. Now you
can keep recognition settings and options in system
registry. One minor bug with MIDI file writing fixed.
New in Version 2.51:
Two bugs were fixed: one with FFT
transform, and one with 44100Hz WAVE buffering. Quality
of FFT method improved greatly, try it!

Just
a few words on how this program works:
Every musical note has pitch, which
corresponds to the frequency of main tone. Modern musical
scale has almost 100 pitches with frequencies from approximately
30 hertz to 4,5 kilohertz. Neighbor notes frequencies
(C and C#, E and F) are always related as 2 in 1/12
power, so notes making an octave interval (=12 smallest
called semitones) have frequencies rated as 1:2. There
are other scales too, but they are rarely used.
WIDI performs music recognition
in several steps:
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.
