AKoff
Music Composer is a music recognition tool which performs Wave
to Midi conversion. Composer recognizes polyphonic music from
microphone (other Wave input or file) and converts it into
Midi sequences.
You can compose
music without MIDI keyboard and even without knowlege 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.
AKoff Music Composer Features:
- Restriction of
recognized pitch range.
- Tracking note dynamics
and pitch bends.
- Using different harmonic
models to improve recognition of appropriate instruments.
- Higher harmonics
filtering.
- Polyphonic music
recognition from pre-recorded WAVE files or directly from
audio input of your sound card in real-time.
- Manual or automatic
noise sensitivity control.
AKoff Music Composer Playback features:
- Sync WAVE and MIDI
playback.
- 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 Timebase).
- PCM WAVE files playing.
How AKoff
Music Composer Works?
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 level.
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.
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. |
