Abstract:
Active control is a technique historically used to reduce noise pollution by applying secondary sources. Numerous applications have subsequently been developed in various fields (acoustic absorption, structural vibration control, etc.), thanks to the high efficiency of this method. Indeed, it remains the most effective method in the low-frequency range (typically below a hundred Hz), and the vast majority of systems using active control feature a system for adapting to variations in external disturbances.
The application of active control to musical instruments brings many advantages to musicians and composers in the creation of augmented instruments. In effect, it extends the range of sounds naturally offered by the instrument by simultaneously modifying the radiated sound and the auditory and haptic feedback experienced by the performer. This technique therefore differs from a simple audio effect added to a recording.
Our research focuses on the trombone, with the aim of modulating in real time the spectrum of sound naturally emitted by the resonances of a human vocal tract, known as formants. The aim is to apply a vowel timbre to the sound of the trombone.
