The objective of this work is to embed watermark information into digital audio data as the deterioration of sound quality is not perceivable to human ears. And hence, we consider that watermark information is embedded in the consonance to melody line or bass line. Generally, unison, octave, perfect fifth and perfect fourth are called consonance and human ears can hardly feel annoyed for consonance...
Leveraging on the strength of energy-based processing for transient detection and pitch-based processing for softer onsets detection, we present a system that combines both energy and pitch cues for detecting onsets from different instrument categories. Given an audio input from an arbitrary instrument category, the system performs preliminary onset categorization based on the general note characteristics...
In this paper, a new type of metric that defines the similarity between musical audio signals is proposed. Based on the spectral flatness criterion, those metrics achieve low computational cost and low sensitivity to acoustical degradations. Validation is performed by studying the ability of the proposed metric to determine whether two audio signals have been played by the same musical instrument...
The synthesis of sound based on physical models of 2-D percussion instruments is problematic and has been approached only infrequently in the literature. Beyond the computational expense inherent to the simulation of 2-D systems, a deeper difficulty is in dealing with the strong nonlinearity exhibited by thin structures when struck-this nonlinearity leads to phenomena which are not captured, even...
In the vocal communication, we are able to detect the position of a source sound in 3D space, extract particular sound from mixed sounds, and recognize what the sound is. An ability that extracts and recognizes particular sound in noisy environment is called cocktail party effect. By realizing this mechanism with a computer, new applications will be presented to be utilized in the communication with...
In this paper a novel technique for efficient synthesis of waveforms generated by musical instruments is presented. This methodology represents single tones produced by musical instruments as a series of orthogonal Bessel functions, similarly to an additive synthesis that, instead, uses sinusoidal partials. Bessel functions possess a pitch that slowly varies with time, and are thus suited to model...
In this paper an automated method to recognize the musical instruments playing the musical signals is presented. Various features of the musical instruments and musical signals are investigated. The features can broadly be grouped into three categories: temporal, spectral, and cepstral features. A composite neural network structure is proposed as the classifier. The performance of the composite neural...
In this paper we discuss the problem of partial tracking as applied to music signals, and propose a tracking algorithm based on Kalman filtering. This algorithm is capable of tracking both frequency and power partials, which are used in different areas of music signal analysis. We introduce a set of state-space models for our signals based on the evolution of frequency and amplitude in different classes...
The implementation of physical models of musical instruments by finite difference methods can be highly computationally complex. This paper investigates the use of FPGAs to accelerate these numerical methods to allow real time production of sounds for musical applications. The methodology to derive a circuit architecture that effectively exploits the types of concurrency in the algorithm for real...
