Resumo: | |||||||||||||
Audio quality degradation can have many causes. For musical
applications, this fragmentation may lead to highly unpleasant experiences.
Restoration algorithms may be employed to reconstruct missing parts of
the audio in a similar way as for image reconstruction - in an approach
called audio inpainting. Current state-of-theart methods for audio inpainting
cover limited scenarios, with well-defined gap windows and little variety
of musical genres. In this work, we propose a Deep-Learning-based (DLbased)
method for audio inpainting accompanied by a dataset with random
fragmentation conditions that approximate real impairment situations. The
dataset was collected using tracks from different music genres to provide a
good signal variability. Our best model improved the quality of all musical
genres, obtaining an average of 13.1 dB of PSNR, although it worked better
for musical genres in which acoustic instruments are predominant.
