In audio spectral analysis, the Fourier method is popular because of its stability and its low computational complexity. It suffers however from a time-frequency resolution trade off and is not particularly suited for aperiodic signals such as exponentially decaying ones. To overcome their resolution limitation, additional techniques such as quadratic peak interpolation or peak picking, and instantaneous frequency computation from phase unwrapping are used. Parameteric methods on the other hand…

Superresolution underwater acoustics
TLDR
The application of some recent results in exponential analysis and sparse interpolation to underwater acoustics is explored, in a joint effort from marine engineers and computational mathematicians, to recover from possible aliasing introduced by the subsampling.
Regular Sparse Array Direction of Arrival Estimation in One Dimension
TLDR
A novel technique that makes use of two sparse non-Nyquist regularly spaced antenna arrays, where one of the arrays is just a shifted version of the other, which offers several advantages over the use of traditional dense Nyquist-spaced arrays, while maintaining a comparable algorithmic complexity for the analysis.
Sparse Multidimensional Exponential Analysis with an Application to Radar Imaging
TLDR
A $d$-dimensional exponential analysis algorithm that offers a range of advantages compared to other methods that does not suffer the curse of dimensionality and only needs $O(O) to be implemented.

TLDR
Three methods (phase vocoder, spectral reassignment, derivative algorithm) equally efficient: they are in fact different formulations of the best analysis method based on the Fourier spectrum.
A perceptual subspace approach for modeling of speech and audio signals with damped sinusoids
TLDR
This work shows how to combine well-known subspace based estimation techniques with a recently developed perceptual distortion measure, in order to obtain an algorithm for extracting perceptually relevant model components.
Robust exponential modeling of audio signals
TLDR
It is shown that by using a proper segmentation of the input data into variable length segments the signal-to-noise ratio can be drastically improved as compared to a fixed-length analysis.

TLDR
It is found through perturbation analysis and simulation that, for signals with unknown damping factors, the pencil method is less sensitive to noise than the polynomial method.
