AbstractThis paper presents a study of blowing pressure pro les acquired from recorder playing. Blowing pressure signals are captured from real performance by means of a a low-intrusiveness acquisition system constructed around commercial pressure sensors based on piezoelectric transducers. An alto recorder was mechanically modi ed by a luthier to allow the measurement and connection of sensors while respecting playability and intrusiveness. A multi-modal database including aligned blowing pressure and sound signals is constructed from real practice, covering the performance space by considering di erent fundamental frequencies, dynamics, articulations and note durations. Once signals were pre-processed and segmented, a set of temporal envelope features were de ned as a basis for studying and constructing a simpli ed model of blowing pressure pro les in di erent performance contexts
