Eluding the Physical Constraints in a Nonlinear Interaction Sound Synthesis Model for Gesture Guidance
Applied Sciences, 2016Co-Authors: Etienne Thoret, Mitsuko Aramaki, Sølvi Ystad, Charles Gondre, Richard Kronland-martinetAbstract:In this paper, a flexible control strategy for a Synthesis Model dedicated to nonlinear friction phenomena is proposed. This Model enables to synthesize different types of sound sources, such as creaky doors, singing glasses, squeaking wet plates or bowed strings. Based on the perceptual stance that a sound is perceived as the result of an action on an object we propose a genuine source/filter Synthesis approach that enables to elude physical constraints induced by the coupling between the interacting objects. This approach makes it possible to independently control and freely combine the action and the object. Different implementations and applications related to computer animation, gesture learning for rehabilitation and expert gestures are presented at the end of this paper.

Controlling a non linear friction Model for evocative sound Synthesis applications
2013Co-Authors: Etienne Thoret, Mitsuko Aramaki, Richard Kronland-martinet, Charles Gondre, Sølvi YstadAbstract:In this paper, a flexible strategy to control a Synthesis Model of sounds produced by non linear friction phenomena is proposed for guidance or musical purposes. It enables to synthesize different types of sounds, such a creaky door, a singing glass or a squeaking wet plate. This approach is based on the action/object paradigm that enables to propose a Synthesis strategy using classical linear filtering techniques (source/resonance approach) which provide an efficient implementation. Within this paradigm, a sound can be considered as the result of an action (e.g. impacting, rubbing, ...) on an object (plate, bowl, ...). However, in the case of non linear friction phenomena, simulating the physical coupling between the action and the object with a completely decoupled source/resonance Model is a real and relevant challenge. To meet this challenge, we propose to use a Synthesis Model of the source that is tuned on recorded sounds according to physical and spectral observations. This Model enables to synthesize many types of non linear behaviors. A control strategy of the Model is then proposed by defining a flexible physically informed mapping between a descriptor, and the non linear Synthesis behavior. Finally, potential applications to the remediation of motor diseases are presented.

Navigating in a space of synthesized interaction-sounds: rubbing, scratching and rolling sounds
2013Co-Authors: Simon Conan, Etienne Thoret, Mitsuko Aramaki, Richard Kronland-martinet, Charles Gondre, Olivier Derrien, Sølvi YstadAbstract:In this paper, we investigate a control strategy of synthesized interaction-sounds. The framework of our research is based on the {action/object} paradigm that considers that sounds result from an action on an object. This paradigm presumes that there exists some sound invariants, i.e. perceptually relevant signal morphologies that carry information about the action or the object. Some of these auditory cues are considered for rubbing, scratching and rolling interactions. A generic sound Synthesis Model, allowing the production of these three types of interaction together with a control strategy of this Model are detailed. The proposed control strategy allows the users to navigate continuously in an ''action space'', and to morph between interactions, e.g. from rubbing to rolling.

2013Co-Authors: Simon Conan, Mitsuko Aramaki, Richard Kronland-martinet, Sølvi YstadAbstract:This paper presents a rolling sound Synthesis Model which can be intuitively controlled. To propose this Model, different aspects of the rolling phenomenon are explored : physical Modeling, perceptual attributes and signal morphology. A source-filter Model for rolling sounds Synthesis is presented with associated intuitive controls.

From shape to sound: sonification of two dimensional curves by reenaction of biological movements
2012Co-Authors: Etienne Thoret, Jean-luc Velay, Mitsuko Aramaki, Richard Kronland-martinet, Sølvi YstadAbstract:Sonifying two dimensional data is a common problem. In this study, we propose a method to synthesize sonic metaphors of two dimensional curves based on the mental representation of the sound produced by the friction of the pencil when somebody is drawing or writing on a paper. The relevance of such approach is firstly presented. Secondly, Synthesis of friction sounds allows to investigate the relevance of the kinematics in the perception of a gesture underlying a sound. In third part, a biological law linking the curvature of a shape to the velocity of the gesture which have draw the shape is calibrated from the auditory point of view. It enables to generate friction sounds with a physically based Synthesis Model from a given shape.

supernova type ia progenitors from merging double white dwarfs using a new population Synthesis Model
Astronomy and Astrophysics, 2012Co-Authors: Silvia Toonen, G Nelemans, S Portegies F ZwartAbstract:Context. The study of Type Ia supernovae (SNIa) has lead to greatly improved insights into many fields in astrophysics, e.g. cosmology, and also into the metal enrichment of the universe. Although a theoretical explanation of the origin of these events is still lacking, there is a general consensus that SNIa are caused by the thermonuclear explosions of carbon/oxygen white dwarfs with masses near the Chandrasekhar mass. Aims. We investigate the potential contribution to the supernova Type Ia rate from the population of merging double carbon-oxygen white dwarfs. We aim to develope a Model that fits the observed SNIa progenitors as well as the observed close double white dwarf population. We differentiate between two scenarios for the common envelope (CE) evolution; the α-formalism based on the energy equation and the γ-formalism that is based on the angular momentum equation. In one Model we apply the α-formalism always. In the second Model the γ-formalism is applied, unless the binary contains a compact object or the CE is triggered by a tidal instability for which the α-formalism is used. Methods. The binary population Synthesis code SeBa was used to evolve binary systems from the zero-age main sequence to the formation of double white dwarfs and subsequent mergers. SeBa has been thoroughly updated since the last publication of the content of the code. Results. The limited sample of observed double white dwarfs is better represented by the simulated population using the γ-formalism for the first CE phase than the α-formalism. For both CE formalisms, we find that although the morphology of the simulated delay time distribution matches that of the observations within the errors, the normalisation and time-integrated rate per stellar mass are a factor ∼ 7 − 12 lower than observed. Furthermore, the characteristics of the simulated populations of merging double carbon-oxygen white dwarfs are discussed and put in the context of alternative SNIa Models for merging double white dwarfs.
