If you ever tried to fit accompaniment or tune to your favorite song, you may be already familiar that this process is time consuming and effortful.
WIDI Recognition System aims to help you with this. WIDI allows to transcribe audio recording (Wave, MP3, CD-Track or other format) into MIDI file, the latter being in fact notation of recorded music. WIDI allows to transcribe polyphonic recordings, not just a single tune. The output file follows MIDI standard and therefore can be opened and edited in any Note editor.
Professional edition of WIDI additionally includes TrueTone MIDI Editor designed for further refining the resultant MIDI in a fast and easy way.

The plug-in transcribes music in real-time. The signal spectra, along with recognized notes are displayed in plug-in's window. Also, plug-in displays detected chords in conventional letter notation. The adjustable recognition parameters serve to improve the recognition quality. The plug-in supports several MIDI output methods, including recording to MIDI file.

Note, WIDI Audio To MIDI plug-in is not a standalone program but requires a VST or AU host program.

Wave, mp3 and midi are the most popular file formats for storing music. That is why the question "How to convert one format to another?" is very popular. Here we explain in brief the difference between Wave, MP3 and MIDI.

The most simple is Wave. It is a record of sound pressure on microphone on time. Any sound can be recorded as wave file, but wave does not allow to edit components of sound and occupies a lot of space. MP3 is a compressed wave. It takes several times less space, but does not allow to separate and edit components as well.

In opposite, MIDI can store only musical sounds. MIDI is a command system, containing information about a note, about the instrument and its change, the length of pressing and so on. This kind of a record can easily be edited and takes less storage space than wave. More information about MIDI can be found on What is MIDI page (in English).

The difference between Wave and MIDI is much the same as that between the typed text and an its image. It is easy to convert typed text to image, but the reverse operation is much more laborious and ambiguous. For example, automatic recognition of hand-writing can't be accomplished without errors till now.

We work on algorithms that analyze musical audio recordings and automatically reconstructs notation of musical piece.
