A multi-level tonal interval space for modelling pitch relatedness and musical consonance
In this paper we present a 12-dimensional tonal space in the context of the Tonnetz, Chew’s Spiral Array, and Harte’s 6-dimensional Tonal Centroid Space. The proposed Tonal Interval Space is…
Improved estimation of the amplitude envelope of time-domain signals using true envelope cepstral smoothing
This work proposes a method to obtain a smooth function that approximately matches the main peaks of the waveform using true envelope estimation, dubbed true amplitude envelope, a cepstral smoothing technique that has been shown to outperform traditional envelope estimation techniques both in accuracy of estimation and ease of order selection.
Designing Ensembles of Fuzzy Classification Systems: An Immune-Inspired Approach
An immune-based approach for designing of fuzzy systems based on the clonal selection, hypermutation and immune network principles is proposed, and a significant improvement is obtained in the correct classification rate, outperforming the single best classifier.
Automatic Timbral Morphing Of Musical Instruments Sounds By High-Level Descriptors
This work presents automatic timbral morphing techniques applied to musical instrument sounds using high-level descriptors as features, which are measures of the acoustic correlates of salient timbre dimensions derived from perceptual studies.
The Role of Time in Music Emotion Recognition: Modeling Musical Emotions from Time-Varying Music Features
It is argued that time is neglected in MER even though musical experience is intrinsically temporal, and that the temporal variation of music features rather than feature values should be used as predictors in MER.
A source-filter model for musical instrument sound transformation
Estimation and representation techniques that give totally independent and intuitive control of the spectral envelope model and the frequencies of the partials to perform perceptually related sound transformations are presented.

A penalty function that encodes musical rules to automatically generate chord progressions is proposed and an artificial immune system (AIS) is used to minimize the penalty function when proposing candidates for the next chord in a sequence.
AUTOMATIC SEGMENTATION OF THE TEMPORAL EVOLUTION OF ISOLATED ACOUSTIC MUSICAL INSTRUMENT SOUNDS USING SPECTRO-TEMPORAL CUES
The automatic segmentation of isolated musical instrument sounds according to the temporal evolution is not a trivial task. It requires a model capable of capturing regions such as the attack, decay,…
Musical Instrument Sound Morphing Guided by Perceptually Motivated Features
This work investigates several spectral envelope morphing techniques to determine which spectral representation renders the most linear transformation in the spectral shape feature domain and concludes that interpolation of cepstral coefficients results in the mostlinear temporal envelope morph.
Interactive Control of Evolution Applied to Sound Synthesis
A sound synthesis method that utilizes evolution as generative paradigm is presented and a sound taxonomy based on an objective and a subjective criterion is presented to evaluate the results.
