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 modeling. In all three of these cases, detailed information about what is played(More)
We propose a physical model for the Gyil, an African pentatonic 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)
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)
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)
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)
High-dimensional optimization problems may be addressed using populational meta-heuristics, whose statistical properties may indicate important characteristics of the optimization process. There is a great number of these properties, which means their joint visualization may become impractical. We developed a method for sonically displaying characteristics(More)
A common approach to the detection of simultaneous musical notes in an acoustic recording involves defining a function that yields activation levels for each candidate musical note over time. These levels tend to be high when the note is active and low when it is not. Therefore, by applying a simple threshold decision process, it is possible to decide(More)
