Reflective Optical Pickup For Violin
نویسندگان
چکیده
We present here the development of optical pickup for acoustic violin. Unlike other optical pickups, this one works in a reflective mode which is potentially less intrusive. This pickup, aimed principally at pitch tracking, uses a modulation technique to improve the signal-to-noise ratio, and limit artifacts of the ambient light.

Near-Field Optical Reflective Sensing for Bow Tracking
This paper explores the potential of near-field optical reflective sensing for musical instrument gesture capture. Near-field optical sensors are inexpensive, portable and nonintrusive, and their high spatial and temporal resolution makes them ideal for tracking the finer motions of instrumental performance. The paper discusses general optical sensor performance with detailed investigations of ...
متن کاملThe Overtone Fiddle: an Actuated Acoustic Instrument
Dan Overholt Department of Architecture, Design and Media Technology Aalborg University, Denmark Niels Jernes Vej 14, 3-107 [email protected] ABSTRACT The Overtone Fiddle is a new violin-family instrument that incorporates electronic sensors, integrated DSP, and physical actuation of the acoustic body. An embedded tactile sound transducer creates extra vibrations in the body of the Overtone Fi...
متن کاملMusical instrument recordings made with a fiber Fabry-Perot cavity: photonic guitar pickup.
A 1 cm long, low-finesse fiber-optic cavity was used as a transducer for the vibrations of the soundboard of an acoustic guitar and of a violin. The reflected light is detected and then amplified and recorded using conventional audio instrumentation. The fiber-optic pickup is found to have a high response range in both amplitude (up to 100 microm displacement) and audio frequency (DC to 20 kHz)...
متن کاملCombining Performance Actions with Spectral Models for Violin Sound Transformation
In this work we present a violin timbre model that takes into account performance gestures. It is built by analysis of performance data using machine learning methods and it is able to predict the timbre given a set of performance actions. Gestural data and sound are synchronously captured by means of 3D motion trackers attached to the instrument and a bridge pickup. The model is used for sampl...
متن کاملModeling Moods in Violin Performances
In this paper we present a method to model and compare expressivity for different Moods in violin performances. Models are based on analysis of audio and bowing control gestures of real performances and they predict expressive scores from non expressive ones. Audio and control data is captured by means of a violin pickup and a 3D motion tracking system and aligned with the performed score. We m...
