Wav to MIDI converter
This software is designed for recognition of polyphonic music from audio source
and its conversion to MIDI score. Now one can compose music without MIDI keyboard
and even without knowledge of notes or how to play musical instruments. It is as
easy as humming a tune into a microphone and Composer will do the rest. Composer
will take into consideration individual performance style tracking note dynamics
and pitch bends.
Polyphonic music recognition from pre-recorded WAVE files or directly from audio
input of your sound card in real-time.
Tracking note dynamics and pitch bends.
Using different harmonic models to improve recognition of appropriate instruments.
Higher harmonics filtering.
Restriction of recognized pitch range.
Manual or automatic noise sensitivity control.
Playback window (main):
PCM WAVE files playing.
Standard MIDI files playing.
Muting and Soloing MIDI Tracks.
Changing MIDI track name, instrument, volume and pan.
MIDI track deleting.
New MIDI file settings (Tempo and Time base).
Sync WAVE and MIDI playback.
How It Works?
Composer analyzes a stream of audio signals from pre-recorded WAVE files or directly
from audio input of your sound card in real-time. It can be sound from microphone,
linear input or audio CD.
Composer normally recognizes polyphonic music with one instrument or voice. This
means you won't get the appropriate results if you try to recognize many instruments
playing at the same time especially with drums. Composer determines note dynamics
and frequencies and translates this information into MIDI events. Composer doesn't
automatically recognize the types of sounding instruments. Moreover, human voice
and instruments have various timbres and complicated harmonic components, therefore
recognition accuracy depends on concrete instrument or singing style. Also the recognition
is influenced by quality of WAVE recordings such as background noises and recording
The complicated mathematical algorithms of DSP (Digital Signal Processing) require
a great amount of calculations and consequently a fast computer. When recognizing
audio input in real-time, Composer only works reliably on Pentium 150 and higher
processors. On weaker machines, the incorrect working or dead halt of the program
may occure, which is removed through pressing Ctrl-Alt-Del keys.
During recognition the recorded notes are automatically shown on the graphic
keyboard. After recognition is stopped, you can play and adjust the obtained melody.
You can select the playback MIDI instrument, change octave and also try to correct
music scale or use Pitch Bend Control. Further you can add the recorded track to
the general list of MIDI tracks and then save the generated MIDI file. The last
feature is accessible only in the registered version. Play piano keyboard online.
If some notes are recognized incorrectly, you can open the saved file in any
MIDI editor and manually correct your score. If you have MIDI keyboard, it will
be easier to play with keyboard entering results into MIDI editor. But if you aren't
a musician, Composer will help you to record your own melody in a popular MIDI format
using only your voice or your non-MIDI instrument.
