Code release: FAuST 1.1 for Approximate Fast Graph Fourier Transforms.

FAµST is a toolbox useful to decompose a given dense matrix into a product of sparse matrices in order to reduce its computational complexity (both for storage and manipulation). Such matrices can be used to speed up iterative algorithms commonly used for solving high dimensional linear inverse problems.

This release (FAuST Matlab version 1.1) includes code to reproduce Graph Signal Processing experiments (Approximate Fast Graph Fourier Transforms) from the paper

  • Le Magoarou L., Gribonval R. and Tremblay N., “Approximate fast graph Fourier transforms via multi-layer sparse approximations”, IEEE Transactions on Signal and Information Processing over Networks,2017. <https://hal.inria.fr/hal-01416110>

Release: A-SPADE, the Sparse Audio Declipper

Ever faced saturated audio recordings ? Try A-SPADE, the Sparse Audio Declipper.

Clipping, also known as saturation, is a comon phenomenon leading to sometimes seriously distorted audio recordings. Declipping consists in performing the inverse process, to restore saturated audio recordings and improve their quality. A-SPADE is a declipping algorithm developed by PANAMA. It is based on on the expression of declipping as a linear inverse problem and the use of analysis sparse (aka cosparse) regularization in the time-frequency domain.

You can listen to sound examples or try it on your own files in your web browser using A-SPADE’s online implementation on A||GO, Inria’s web platform for technology demonstration.
