7Canaries Professional performs automated recognition
of polyphonic music, stored in MP1, MP2, MP3, MPP,
MPA, AIF, SND, AU, WAVE formats as well as audio CD
tracks. In real-time mode it instantly converts music
coming through the microphone or line input of your
computer into a MIDI sequence. 7Canaries Professional
contains interactive Note Editor.

Recognizing pre-recorded music allows converting
digital sound to MIDI format. MIDI file takes hundreds
times less space than any digital sound format, which
allows you to use it as a melody for your web page or
make a preview of your mp3 Internet music collection.
As MIDI file is, in fact, a layout of music, you can
change its arrangement in contrast to digital sound.
Instruments, number of voices or melody itself can be
easily modified using any third-party score editor,
which allows creating remixes, variations and printing
musical notation. You may even put the melody in your
mobile phone!

On-fly recognition is a process performed in real-
time, without noticeable delay. Detected notes can be
either recorded or played in real time, or both. Thus
you can change instruments in real-time, for example,
play the guitar and get piano sound.

7Canaries provides four different note detection
algorithms. A number of filtering options allows to
leave aside odd notes. Monophonic methods provide
recognition of one (the loudest) voice in melody but
with great accuracy. Polyphonic method transcribes
several voices.
