Estudi de casos pel control de śıntesi d’instruments musicals virtuals mitjançant la veu cantada. Case studies for controlling virtual instruments synthesis using the singing voice

Parameters Ssynth Timbre dynamics Loudness Fundamental Frequency Protocol The goal of this experiment is to evaluate the voice timbre, in this case the ”vowel-space” for controlling a perceptual attribute of the sytnhesized sound (brightness). This task is a priori not intuitive for a singer, since it would tend to control the clarinet dynamics with the loudness, which relates to the actual acoustical behaviour of clarinet . Nevertheless, our goal is to exploit the voice expressive capabilities, not in a traditional context, but rather to control sound generation in a wider scope. In this sense, the singer has to learn this new context to perform tasks that he or she is not used to. As we menrioned, this experiment is a first attempt to compare the voice witj existing musical controllers. In our case, a MIDI Windcontroller (Yamaha WX5). For the protocol, we defined eight tasksto accomplish by the participants. More specifically, we look at the control of a perceptual atirbute of the synthesizer, the brightness, which is related to the timbre dynamics of the clarinet. For each task the procedure consists in listening a reference musical phrase of a real clarinet recording. Then, the subject has to repeat the same phrase by focusing on the brightness of the synthesized sound.
