چکیده

This paper presents a novel music representation using a Variable Resolution Transform (VRT) which is particularly well adapted for music audio analysis. The VRT is inspired by continuous wavelet transform and it applies different wavelet function at different scale. This method enables a good flexibility of the transform in order to follow log scale of musical note frequencies and at the same time to maintain good time and frequency resolution. As an example of application of this novel VRT, a multiple f0 detection algorithm is presented and evaluated showing convincing results. Furthermore, a direct comparison with the FFT applied to the same algorithm is also provided.

An Efficient Multi-Resolution Spectral Transform for Music Analysis

In this paper we focus on multi-resolution spectral analysis algorithms for music signals based on the FFT. Two previously devised efficient algorithms (efficient constantQ transform [1] and multiresolution FFT [2]) are reviewed and compared with a new proposal based on the IIR filtering of the FFT. Apart from its simplicity, the proposed method shows to be a good compromise between design flex...

Harmonic Frequency Estimation Based on Modified-MUSIC Algorithm in Power System

Abstract: This paper presents a new harmonics frequency estimation method. Unlike the conventional harmonic frequency estimation method (fast Fourier transform), the new algorithm is based on spectrum analysis techniques often used to estimate the direction of angle; the most popular is the multiple signal classification (MUSIC) algorithm. The drawbacks of MUSIC algorithm are concluded. Improve...

Improved OAM-Based Radar Targets Detection Using Uniform Concentric Circular Arrays

Without any relative moves or beam scanning, the novel Orbital-Angular-Momentum(OAM)-based radar targets detection technique using uniform concentric circular array (UCCA) shows the azimuthal estimation ability, providing new perspective for radar system design. However, the main estimation method Fast Fourier Transform (FFT) under this scheme suffers from low resolution. As a solution, this pa...
