Tensor completion algorithms for estimating missing values in multi-channel audio signals
(Pergamon-Elsevier Science Ltd, 2021-11)
Audio inpainting is a widely used technology in the real world since audio signals with missing data are pervasive in many scenarios. The majority of existing works address the time gaps in single-channel audio signals, ...
Pitch detection algorithms based on zero-cross rate and autocorrelation function for musical notes
(2008-09-22)
This paper discusses two pitch detection algorithms (PDA) for simple audio signals which are based on zero-cross rate (ZCR) and autocorrelation function (ACF). As it is well known, pitch detection methods based on ZCR and ...

Beamforming echo-localization system using multitone excitation signals
(Institute of Electrical and Electronics Engineers Inc., 2017)
Determining the position of a target is the central issue in several engineering problems, from computer vision to sonar or radar systems. Echo-localization systems use the reflected sound waves to extract information from ...
Autoregressive decomposition and pole tracking applied to vocal fold nodule signals
(2007-08-01)
This letter describes a novel algorithm that is based on autoregressive decomposition and pole tracking used to recognize two patterns of speech data: normal voice and disphonic voice caused by nodules. The presented method ...
