WIDI Recognition System is a polyphonic Audio to MIDI transcriber with an advanced MIDI Editor. The main function of the program is to transcribe Audio files into MIDI, and then to help with quick and efficient rearrangement of the converted file. The program recognizes CD tracks, MP3 and Wave files and automatically produces polyphonic MIDI files in seconds. In addition, WIDI Recognition System is capable of converting music on the fly, as you sing or play a musical instrument. WIDI's innovative recognition algorithms guarantee the best conversion quality ever available.

TrueTone Editor is the tool in the WIDI Recognition System Professional Edition that allows users to correct the results of automatic recognition with a visual comparison of spectrogram peaks to the notes. Score Viewer automatically notates MIDI data as soon as any changes are made. Users possess the options of adding and deleting musical notes, adjusting pitch and duration, and enabling playback, including synchronized play with the source audio file. To enhance score readability, the TrueTone Editor manages bar-lines for easy positioning, addition or deletion in visual mode, or one can use the Tapping Tool, arranging bar-lines by ear. Since WIDI 4.5, slowed down audio playback is also available for more efficient manual score correction.

WIDI supports Recognition Presets for different types of music, predefined or created by users. Recognition Wizard will help you to get your first results just in a few moments after the initial start-up, and familiarizes you with the program at the same time.

Whether you are an amateur or a professional, WIDI Recognition System will help you to transcribe or rearrange music compositions, and learn more about music.
