All Analysis Synthesis Perception Sound Control Spatialization
Gabor Frames

The Gabor transform is a sampled version of the Short Time Fourier Transform. For suitable choices of the analysis window and of the time-frequency...

Gabor Frames
Brain Imaging

We examined neural bases of the brain processes (using Event Related Potentials method) involved in the categorization and conceptual priming protocols, in which special care...

Brain Imaging
Sound and Motion

Perception of motion is here studied for monophonic, abstract sounds, in the case of biological movement and in multimodal situations (e.g. driving a car)...

Sound and Motion
Musical Sounds

Synthesis models are here developed for woodwinds (flutes and clarinets), string instruments (guitar, piano) and percussive instruments (xylophone and drums). Sound control is studied...

Musical Sounds
Timbre

Analysis-synthesis approaches are here used to identify and extract timbre descriptors that at best characterize evocations induced by sounds. Perceptual evaluations are correlated with...

Timbre
Sound and Pathologies

Schizophrenia : sounds can constitute revelant means to investigate abnormal perceptual experiences in patients with schizophrenia. We designed calibrated environmental and abstract sounds to...

Sound and Pathologies
Sound Design

High-level controls of sound synthesis processes enabling the design of sounds from semantic labels or gestures were proposed. Inspired from the ecological approach, we...

Sound Design
Environmental Sounds

The class of environmental sounds covers a large variety of sounds since it relates to events occurring in our everyday life (like rain, wind,...

Environmental Sounds
Wavelets

Wavelet transforms are decompositions of arbitrary signals into localized contributions labelled by a scale parameter. Our group was involved at the very early stage...

Wavelets
Solid Sounds

Solid sounds are one of the main categories of environmental sounds. They are produced either by the interaction between several objects (e.g. impact, friction,...

Solid Sounds
Industrial Sounds

Industrial sounds often refer to annoyance. Nevertheless, these sounds may content valuable information to be highlighted: is the car door well closed? Does the...

Industrial Sounds
Sonification

Sonification consists in associating data obtained by performing measurements of various kinds with sounds. The main idea is to use human beings’ natural perceptual...

Sonification
Abstract Sounds

Abstract sounds are sounds in which the physical sources cannot be easily recognized and are known to help subjects focus on intrinsic sound properties...

Abstract Sounds
Time-Frequency Masking

The perception of one sound can be affected by the presence of another sound. This effect is due to the masking properties of the...

Time-Frequency Masking
Musical Interpretation

Synthesis models are here used to investigate the percpetual influence of control parameters (pressure and aperture) in clarinet performances. Perception of timbre variations in...

Musical Interpretation
Audio Coding

One of the greatest challenges in signal processing is to develop efficient signal representations allowing to describe the signal with a minimal amount of...
