This paper presents a novel method of classifying musical sounds. An earlier work has shown the ability of a subset of the timbre attributes of musical sounds to classify musical sounds correctly in instrument families. This work focuses on the interpretation of the timbre attributes. The question is: which timbre attributes are useful for the classification of the sounds? These attributes are ...

introduction: children with cochlear implants (cis) may experience few opportunities for positive musical experiences, and musical perception is therefore often not sufficiently developed. this paper investigates and discusses the relationship between intelligence quotient (iq) and musical ability in children with cis compared with children with normal hearing.                                  ...

Building upon convolution-based EQ (Settel and Lippe 1997 rev. 2001) spectral analysis data is utilized to attenuate FFT bins (derived from an FFT analysis of noise) to create an FFT/IFFT-based subtractive analysis/resynthesis module. Techniques for modification of analysis data prior to resynthesis, producing a variety of effects, are examined and demonstrated. Methods for retaining informatio...

This paper presents robust speech enhancement using noise estimation based on smoothing of spectral noise floor (SNF) for nonstationary noise environments. The spectral gain function is obtained by well-known log-spectral amplitude (LSA) estimation criterion associated with the speech presence uncertainty. The noise estimate is given by averaging actual spectral power values, using a smoothing ...

Whilst musical transients are generally acknowledged as holding much of the perceptual information within musical tones, most research in sound analysis and synthesis tends to focus on the steady state components of signals. A method is presented which separates the noisy transient information from the slowly time varying steady state components of musical audio. Improvements of using adaptive ...

This paper presents a model of the envelope of the additive parameters of isolated musical sounds, along with a new method for the estimation of the important envelope splitpoint times. The model consists of start, attack, sustain, release, and end segments with variable split-point amplitude and time. The estimation of the times is done using smoothed derivatives of the envelopes. The estimate...

It is well known that one of the challenges in musical instruments analysis is to obtain relevant signal characteristics and information for sound description and classification. In this paper we study the Peruvian quena flute by means of the Harmonic Band Wavelet Transform (HBWT), a convenient representation for the sound content based on its 1/f fractal characteristics. In order to identify a...

Signal separation is a substantial problem in digital signal processing. The objective of signal separation from a musical composition is to decompose the composition into signals of individual musical instruments. One method that can be used is Projection Pursuit (PP) that similar with Independent Component Analysis (ICA). PP can determine source signals by projecting the data to find the most...

Art, music, and science come together as computer musicians and computer scientists collaborate to create EyeMusic, a system for composing and performing eyecontrolled musical and multimedia compositions. In EyeMusic, an eye-tracking device communicates with a musical and multimedia authoring environment to enable composers and artists to sonify and visualize eye movement data. During a live pe...
