This paper describes a method for melody detection in polyphonic musical signals. Our approach starts by obtaining a set of pitch candidates for each time frame, with recourse to an auditory model. Trajectories of the most salient pitches are then constructed. Next, note candidates are obtained by trajectory segmentation (in terms of frequency and pitch salience variations). Too short, low-sali...

The computational analysis of musical harmony has received a lot of attention the last decades. Although it is widely recognized that extracting symbolic chord labels from music yields useful abstractions, and the number of chord labeling algorithms for symbolic and audio data is steadily growing, surprisingly little effort has been put into comparing sequences of chord labels. This study prese...

A simple but robust and effective method to improve collective pitch control of variable-speed wind turbines given information on future inflow is proposed. The present paper focuses on the design and prospects of a control concept using predictive disturbance compensation. This feed-forward control structure is based on calculation of a future effective wind speed, on static disturbance compen...

The most popular time-frequency analysis tool, the Short-Time Fourier Transform, suffers from blurry harmonic representation when voiced speech undergoes changes in pitch. These relatively fast variations lead to inconsistent bins in frequency domain and cannot be accurately described by the Fourier analysis with high resolution both in time and frequency. In this paper a new analysis tool, cal...

We are interested in developing an automatic emphasis correction system, which converts any unemphasized word in an utterance into emphasized. Analyzing how prosody changes from unaccented to accented is crucial for the task. While previous works on prosody reconstruction only model the prosody contour itself instead of the increment, we propose a framework to study the prosody increment induce...

A full six degrees of freedom (6-DOF) simulation flight dynamics model is applied for the accurate prediction of short and long range trajectories of high and low spin-stabilized projectiles and small bullets via atmospheric flight to final impact point. The projectile is assumed to be both non-flexible and rotationally symmetric about its spin axis launched at low and high pitch angles. The pr...

This paper hypothesizes that listeners who have been exposed to pitch continuum traditions of music, in which microtonal variations are a common occurrence, will have greater sensitivity to pitch changes as compared to listeners who have not. To test this hypothesis, two perceptual experiments are designed and performed in order to study the validity of the trill and glissando thresholds, repor...

An aeroelastic model of a smart rotor system (which incorporates blade-mounted trailing-edge flap actuators and conventional root pitch actuation) is presented in linear time invariant state space form. The servo-flap deflections are modeled as producing incremental lift and moment variations, so that any linear aerodynamic actuator can be evaluated. This smart rotor model is used to conduct pa...

Dialect variations of a language have a severe impact on the performance of speech systems. Therefore, knowing how close or separate dialects are in a given language space provides useful information to predict, or improve, system performance when there is a mismatch between train and test data. Distance measures have been used in several applications of speech processing, including speech reco...

Discrete Cosine Transform (DCT) has similar performance to the Karhunen-Loeve Transform (KLT) & same properties to the Discrete Fourier Transform (DFT). It is advantageous for speech enhancement as it provides better energy compaction capability. Though there is a perfectly stationary signal, frame to frame variations of DCT coefficients are observed. In pitch synchronous analysis DCT based spe...
