About the framework

Welcome to the (SPARE) SParse Audio REstoration project website. You will find below some details about the modeling and algorithmic framework proposed to address audio restoration problems as denoising or declipping.

This work is developed by actual and former members of PANAMA (a joint project-team between INRIA and CNRS).

It is based on the expression of audio reconstruction scenarii as linear inverse problems and the use of analysis, synthesis plain or social sparse time-frequency priors.

Audio Examples

Warning: use Firefox or Google Chrome browsers to play the sounds.

You can listen to denoising audio examples.

You can listen to declipping audio examples.

The examples shown in these two pages are from the RWC Database*.
