The main objective of WIDI is music recognition.
A piece of music can be represented in two forms: waveform or musical notation. Waveform is simply a record of the relation of sound pressure to time. For example, it could be *.wav and *.mp3 files or a tape recording and so on. In this form, the sound exactly duplicates the recording sound. However, in this case, many instruments and sounds, which resound simultaneously, get overlaid. This makes editing of the record, like changing the notes, rearrangement and so on, impossible. A musical notation, like sheet music and MIDI files, is basically a list of commands which note is to be played by what instrument. This kind of a record can easily be edited and takes less storage space than a *.wav file. However, not every sound can be transmitted to MIDI. For example, human speech cannot be transcribed in the note form.
Actually, the task of sound recognition and music recognition in particular, is a serious mathematical task, which doesn't have a universal solution to it yet. Nevertheless, WIDI Recognition System contains advanced algorithms, allowing you, with a sufficient degree of accuracy, to recognize polyphonic pieces. Furthermore a significant number of tuning settings gives you a possibility of enabling the program to recognize different musical styles, tools and so forth, etc.
Opposite to the majority of analogous systems, WIDI is a multifunctional program, including such functions as recording musical programs, waveform displaying, a special notes editor (Professional version only), which is able to perform a visual comparison of the spectrogram of initial musical record and the notes obtained after recognition.
WIDI can use supported sources such as uncompressed wave files, as well as mp3 files, CD-tracks and even the sound, coming directly from a microphone, without recording it into a file (real-time recognition.)
WIDI allows you, obtaining simply a waveform, recognize it and then:
| · | Change the adaptation, tonal range and mode.
|
| · | Collect previews for mp3 files collections
|
| · | Load the favourite melody into your cell phone
|
| · | Receive a musical notation of a composition for performing it with a musical instrument
|
(You may need some other third party software for actual score editing or uploading to cellular phone)
