Audio inpainting live demonstration

This page propose a live demonstration of our audio in-painting algorithm. We do not store any of your files after the processing.

Abstract

We present a method to compensate for long duration data gaps in audio signals, in particular music. To achieve this task, a similarity graph is constructed, based on a short-time Fourier analysis of reliable signal segments, e.g. the uncorrupted remainder of the music piece, and the temporal regions adjacent to the unreliable section of the signal. A suitable candidate segment is then selected through a convex optimization scheme and smoothly inserted into the gap.

Online demonstration

Test our algorithm in four simple steps:

1. Select your file to be in-painted (mp3, wav, flac):
   
   


2. Specify the place to be in-painted
   Initial time in seconds:
   Final time in seconds:
   


3. Lauch the upload and wait for the reconstuction to be done. It usually takes between 30 seconds and 1 minute depending on the server load and the length of your file.
   


4. Download your in-painted file.
