The algorithm for automatic generation of chords receives as main input an abstract map or a harmonic-abstraction that shows the direction and voice movement from chord to chord within …

Section 1 describes the missing fundamental effect and existing methods of Bass Enhancement. Section 2 describes our new developed harmonic generation method followed by overall DSP …

Below is a graphic representing the characteristic curves of a Jfet transistor typical of the type we might want to use to create some 2nd harmonic. It shows the relationships between Drain to …

There exists a number of methods to generate sub-harmonic frequencies for a given audio signal [1-4]. Pitch-changing algorithms which work in the frequency domain [1] require FFT/IFFT …

Uses machine learning/hidden markov models to recognize classical harmonic progressions and algorithmically generate pieces of classical music.

In this paper, we intend to consider the generation of harmonies or chords suitable for music and use a multi-objective algorithm and a combination of human and non-human objective …

In this study, we present a constrained non-linear programming approach based on the Quasi-Newton Broyden–Fletcher–Goldfarb–Shanno (BFGS) algorithm to obtain high-fidelity harmonic …

In this paper we propose a method of creating virtual bass based on a multiband harmonic generation. The proposed algorithm separately generates harmonics for each band whose …

Let's start with a 2 kHz sine wave, and attempt to generate the first subharmonic frequency at 1 kHz. First, let's build a simple function to determine whether the input signal is increasing or …

Harmonic generation (HG, also called multiple harmonic generation) is a nonlinear optical process in which photons with the same frequency interact with a nonlinear material, are "combined", …
