7Canaries 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.
