True random number generators (TRNGs) are important hardware primitives required for
many applications including cryptography, communication, and statistical simulation. This …

In this article, a novel pitch determination algorithm based on harmonic differences method
(HDM) is proposed. Most of the algorithms today rely on autocorrelation, cepstrum, and lastly …

A system and method may be configured to analyze audio information derived from an audio
signal. The system and method may track sound pitch across the audio signal. The tracking …

In this paper we present a personal, cost-effective, multi-parametric monitoring system
based on textile platforms and portable sensing devices for the long term and short term …

BACKGROUND Systems and techniques for tracking Sound pitch across an audio signal
are known. Known techniques implement a transform to transform the audio signal into the …

Abstract Fractional Fourier transform (FrFT) has been proposed to improve the time-
frequency resolution in signal analysis and processing. However, selecting the FrFT …

This paper presents a new pitch-based spectral enhancement algorithm on voiced frames
for speech analysis and noiserobust speech processing. The proposed algorithm …

We propose an acoustic feature for speech recognition based on the combination of MFCC
and fractional Fourier transform (FrFT). The transform orders for FrFT are adaptively set …
