This project aims at studying how recent interactive and interactions technologies would help extend how we play the guitar, thus defining the " multimodal guitar ". Our contributions target three main axes: audio analysis, gestural control and audio synthesis. For this purpose, we designed and developed a freely-available toolbox for augmented guitar(More)
In this paper we present a series of algorithms developed to detect the following guitar playing techniques : bend, hammer-on, pull-off, slide, palm muting and harmonic. Detection of playing techniques can be used to control external content (i.e audio loops and effects, videos, light events, etc.), as well as to write real-time score or to assist guitar(More)
In this project we investigate new ways of diffusing the sound via the use of sound drivers, which enables to turn any surface into audio diffusion surface. This kind of technology can benefit to a lot of varied projects. Our investigations led us to use this technology in two types of application : an artistic one, in which drivers were used with(More)
This paper suggests the use of a plywood panel, which is also a scenographic element in a dance performance, as a flat speaker. The sound emanating from the panel is subjectively different from a traditional loudspeaker, since the sound appears to originate from behind the panel. However, its frequency response is severely coloured by the panel modes, and(More)
This project aims at studying how recent interactive and interaction technologies would help extend how we play the guitar, thus defining the " multimodal guitar ". We investigate two axes, 1) " A gestural/polyphonic sensing/processing toolbox to augment guitar performances " , and 2) " An interactive guitar score following environment for adaptive learning(More)
In this project we present a series of algorithms developed to detect the following guitar playing techniques : bend, hammer-on, pull-off, slide, palm muting, harmonic, plucking point. Via the detection of these information, the instrument can be extended as a natural way to control external content (i.e. loops, audio effects, videos, light changes, etc.).(More)
