Woodify increases the resistance of the instrument by changing its vibrating mode. I allows you to play with a greater air flow. At the same time it makes the sound more focussed and less airy. If you analyse the spectrum of the flute sound you will recognize defined overtones over the played fundamental as well as a characteristic noise fog around 11kHz. This fog is mainly produced by the air stream spread over the embrochure and is very characteristic for the flute sound. In fact this noise fog helps the sound to carry on a long distance, f.e. in a large concert hall. When we focus the tone by changing the embrochure, we reduce this noise fog and increase the harmonics, which result in a more centered tone. However, although the sound feels richer and louder, it does not carry on a long distance so well. WOODIFY works as a tone-centerer; it amplifies the harmonics. At the same time it partially reduces the characteristic noise fog; the tone sounds therefore darker. The higher resistance of the instrument however allows you to play with more air, in turn adjusting the characteristic noise fog. Long story short: You don’t have to work so much to find a focused tone. Concentrate more on getting a big, fluent air stream and you will get an overall louder and more projected sound.
