Each step of the tutorial has a detailed description, images and demos in the Flash format. You can open them in a separate window by clicking thumbnail images.

The detailed description of how to work with the WIDI interface is given in separate paragraphs and highlighted by a smaller font. If you know the interface of the program well, you can skip these paragraphs. The names of buttons and dialog boxes are written in the bold font, while the names of menu items are written in italics. Some of these names are links that refer to the detailed descriptions of the corresponding dialog boxes.

All files mentioned in the tutorial can be downloaded. Links for downloading files are highlighted in blue. It is recommended to download at least the source mp3 file and the final MIDI and wne files.
The best way is to repeat all operations described in this tutorial yourself. It is the quickest way to feel all the peculiarities of working with the program.

If some parts of the tutorial seem unclear or poorly worded, we will be grateful if you tell us your comments and suggestions in the corresponding section of our forum. This link is also available at the end of each page of the tutorial.

As an example, we selected a fragment of Por Unos Dolares Mas from the album Music of the Andes by Inka Wayra provided courtesy of the authors.

First of all, you should listen to the track we are going to recognize. We hear a quite fast guitar accompaniment through the entire piece of music. Flute comes in a few seconds after the track starts and another wind instrument replaces it in the second part – it is Chilli, Andes inhabitants' traditional instrument. In this case, it is important to mention that both wind instruments are monophonic.

First, let us try to recognize the track without changing any parameters. If you have not changed the recognition parameters, it is enough just to start the recognition process, otherwise use the Default button in the Recognition Settings and Equalizer dialog boxes.

Note: Unlike in version 3.3, the MIDI Window appears in version 3.2 by default. To open the TrueTone editor, you should click the Edit MIDI data in TrueTone Editor button in it or just use the Ctrl+Enter key combination.

First of all, look at the (Note Map) at the bottom of the window showing a reduced image of the entire track. You can clearly see smooth melody lines on the note map. It is a good sign, most probably the recognition result will need relatively little manual correction.

Flute comes in approximately at the fourth second and you can see its part as two quite smooth curves coming parallel at the interval of one octave. But a flute is a monophonic instrument while an octave is the interval between the main tone and the first (strongest) overtone. Therefore, the upper voice is an overtone and you should get rid of it. There are two ways to do it: remove the corresponding notes from the resulting file or change the recognition parameters so that a larger part of these notes does not appear there at all. The second method is more preferable because it allows you not to deal with parts of the spectrum that do not carry any musical information and increase the accuracy in the analysis of the remaining part. The highest note in the part of the flute is "Re" of third octave (D-5), and it occurs at the 22d second.
Similarly, you can see from the accompaniment that there are no notes lower "Si" of great octave (B-1) in the track (the lowest note is at the 23d second), it means that all lower notes are an accidental noise and they can be discarded.

Besides, experience shows that it often makes sense to make the melody more prominent (usually it is the top voice) in a piece of music. You can easily do it all using the Equalizer.
