WIDI Recognition System

WIDI Recognition System 4.41

Transcribes regular audio files into the MIDI format

Uses audio algorithms to transcribe music stored in regular formats such as MP3, WMA, WAV, CDA, AIFF, etc. into MIDI notes.

WIDI Recognition System can convert audio to MIDI. This application can recognize not only recorded but also live music. Setting apart the obvious complexity of working with music, which certainly requires specialized artistic and technical knowledge, this utility is quite easy to use. Undoubtedly, the easiest way to start any project is by using a wizard.

As stated, the utility can analyze audio from a variety of sources. When importing recorded music, multiple audio formats are supported, such as WAV, MP3, AIFF, audio CD, and WMA. The application supports playing standard audio and MIDI files, and there’s even the possibility of synchronizing the original music file with the deciphered MIDI. Besides, you can also play a given musical instrument and have the software tool analyze the audio in real time. Luckily, the program is able to achieve high-quality results thanks to the use of various powerful recognition algorithms, of which there are two main types: note detection algorithms can extract notes while the so-called supplementary algorithms can identify additional sound features.

Of course, the results of the recognition process are largely dependent on your ability to use the adequate parameters. This includes using the right algorithms and setting the equalizer properly. Thus, it is always a good idea to try different combinations until the desired quality is reached. In addition, you should consult the excellent help documentation provided with the program.

All in all, WIDI Recognition System can effectively help amateur and professional musicians and composers in their work. Unfortunately, some more sophisticated tasks, such as editing MIDI files and transcribing music are only available from the professional edition, which is, in addition, quite costly.
