bottom layer
(synthesis parameters of the signal model)
designed for the control of the impact sound synthesizer
middle layer
(acoustic descriptors) and

perceived material, size and shape, etc.) and the excitation (force, hardness of the
mallet, impact position, etc.). The middle layer is based on perceptually relevant
acoustic descriptors linked to the invariant sound morphologies (cf. Sect.
4.3.2
).
The bottom layer consists of the set of synthesis parameters (for expert users). Two
mapping strategies are implemented between the layers (we refer to (Aramaki et al.
2010
a) for more details). The
first one focuses on the relationships between verbal
