Radiation impedance control of brass resonators to reshape sounds with vowel spectral envelopes: a numerical study

Proceedings of the 10th Convention of the European Acoustics Association Forum Acusticum 2023
The application of active control to brass instruments brings many benefits to composers and performers, by expanding its sound possibilities. In this paper, we propose to simulate the connection of a static human vocal tract, downstream of the bell, so that the instrument radiates a vowel. To this end, we modulate the spectral envelope of the radiated
