| |  Introduction : [Wave to Midi, MP3 to Mid, CD to Mid converter]
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).

"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.
| Features:
- gets as input both compressed and uncompressed WAVE, MPEG Layer 1, 2 and 3 and CD tracks.
- produces multi-track volume differentiated MIDI files..
- uses simple harmonic model to eliminate wrong notes.
- allows automatic fine tuning to the key of source file.
- does not differentiate instruments in source file, but allows you to use any instrument in the output MIDI file.
- can produce intermediate GS files for quicker operation (See GS files for details).
- pitches to transcribe are selectable (See Equalizer).
- subject to tuning:
- algorithm selection.
- minimal duration of notes (wrong short notes can be cut off).
- number of voices.
- time resolution (usually higher than minimal note duration).
- bass note shifting.
- length of input file is not limited.
