Musical keyboard instruments have a long history, which resulted in many kinds of keyboards (claviers) today. Since the hardware of conventional musical keyboards cannot be changed, such as the number of keys, musicians have to carry these large keyboards for playing music that requires only a small diapason. To solve this problem, the goal of our study is to construct UnitKeyboard, which has o...

Humans, and many non-human animals, produce and respond to harsh, unpredictable, nonlinear sounds when alarmed, possibly because these are produced when acoustic production systems (vocal cords and syrinxes) are overblown in stressful, dangerous situations. Humans can simulate nonlinearities in music and soundtracks through the use of technological manipulations. Recent work found that film sou...

One of the reasons of why some musical instruments more successfully continue their evolution and actively take part in the history of music is partially attributed to the existing compositions made specifically for them, pieces that remain and are still played over a long period of time. This is something we know, performing these compositions keeps the characteristics of the instruments alive...

This short paper follows an earlier NIME paper [1] describing the invention and construction of the Electrumpet. Revisions and playing experience are both part of the current paper. The Electrumpet can be heard in the performance given by Hans Leeuw and Diemo Schwarz at this NIME conference.

This article describes a modified technique for enhancing noisy speech to improve automatic speech recognition (ASR) performance. The proposed approach improves the widely used spectral subtraction which inherently suffers from the associated musical noise effects. Through a psychoacoustic masking and critical band variance normalization technique, the artifacts produced by spectral subtraction...

Speech enhancement methods using spectral subtraction have the drawback of generating an annoying residual noise with musical character. In this paper a frequency domain optimal linear estimator with perceptual post filtering is proposed which incorporates the masking properties of the human auditory system to make the residual noise distortion inaudible. The performance of the proposed enhance...

In this paper we propose a new approach for speech enhancement. The method used to remove the noise components is a combination of two methods: Wavelet de-noising and spectral subtraction. The idea is to apply the spectral subtraction to wavelet approximations and details coefficients. A new parameter for spectral subtraction in unvoiced speech frames is introduced and the existing power factor...

The design, implementation, and evaluation of a system for automatic audio signal classification is presented. The signals are classified according to audio type, differentiating between three speech classes, 13 musical genres, and background noise. A large number of audio features are evaluated for their suitability in such a classification task, including MPEG-7 descriptors and several new fe...

We present the design and implementation of the Conductor's Jacket, a unique wearable device that measures physiological and gestural signals, together with the Gesture Construction, a musical software system that interprets these signals and applies them expressively in a musical context. Sixteen sensors have been incorporated into the Conductor's Jacket in such a way as to not encumber or int...
