The purpose of 7Canaries Professional (by TallStick Software) is to retrieve music scores from audio recordings. It takes a standard WAV file as input, then processes it and outputs a standard MIDI file. Unlike most competitors, it allows you to get several voices (up to nine). The program works with pre-recorded files, and there are user-adjustable parameters to enhance the quality of conversion. 7Canaries Professional contains interactive VisiNote Editor, which is absent in 7Canaries Standard.

7Canaries Professional performs automated recognition of polyphonic music, stored in MP1, MP2, MP3, MPP, MPA, AIF, SND, AU, and WAV 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.
