Hyper-instruments extend traditional acoustic instruments with sensing technologies that capture digitally subtle and sophisticated aspects of human performance. They leverage the long training and skills of performers while simultaneously providing rich possibilities for digital control. Many existing hyper-instruments suffer from being one of a kind(More)
The Gyil is a pentatonic African wooden xylophone with 14-15 keys. The work described in this paper has been motivated by three applications: computer analysis of Gyil performance, live improvised electro-acoustic music incorporating the Gyil, and hybrid sampling and physical mod-eling. In all three of these cases, detailed information about what is played(More)
We propose a physical model for the Gyil, an African pen-tatonic idiophone with wooden bars that have similar sonic characteristics to the western marimba. The primary focus is modeling the gourds that are suspended beneath each bar and have a similar role to the tuned tubes below the bars in western mallet instruments. The prominent effect of these(More)
Music transcription refers to the process of detecting musical events (typically consisting of notes, starting times and durations) from an audio signal. Most existing work in automatic music transcription has focused on offline processing. In this work we describe our efforts in building a system for real time music transcription for the vibraphone. We(More)
An automatic music transcriber is a device that detects, without human interference, the musical gestures required to play a particular piece. Many techniques have been proposed to solve the problem of automatic music transcription. This paper presents an overview on the theme, discussing digital signal processing techniques, pattern classification(More)
We present a content-based music collection exploration tool based on a variation of the Self-Organizing Map (SOM) algorithm. The tool, named SoundAnchoring, displays the music collection on a 2D frame and allows users to explicitly choose the locations of some data points known as anchors. By establishing the anchors' locations, users determine where(More)
We propose and evaluate a system for content-based visualization and exploration of music collections. The system is based on a modification of Kohonen’s Self-Organizing Map algorithm and allows users to choose the locations of clusters containing acoustically similar tracks on the music space. A user study conducted to evaluate the system shows that the(More)
This paper describes an interactive audiovisual musical installation, namely MOTUS, that aims at being deployed using low-cost hardware and software. This was achieved by writing the software as a web application and using only hardware pieces that are built-in most modern personal computers. This scenario implies in specific technical restrictions, which(More)
