Upsampling layers for music source separation
Jordi Pons, Joan Serrà, Santiago Pascual +3
Upsampling artifacts are caused by problematic upsampling layers and due to spectral replicas that emerge while upsampling. Also, depending on the used upsampling layer, such artif…
Adversarial Auto-Encoding for Packet Loss Concealment
Santiago Pascual, Joan Serrà, Jordi Pons
Communication technologies like voice over IP operate under constrained real-time conditions, with voice packets being subject to delays and losses from the network. In such cases,…
PixInWav: Residual Steganography for Hiding Pixels in Audio
Margarita Geleta, Cristina Punti, Kevin McGuinness +3
Steganography comprises the mechanics of hiding data in a host media that may be publicly available. While previous works focused on unimodal setups (e.g., hiding images in images,…
On tuning consistent annealed sampling for denoising score matching
Joan Serrà, Santiago Pascual, Jordi Pons
Score-based generative models provide state-of-the-art quality for image and audio synthesis. Sampling from these models is performed iteratively, typically employing a discretized…
Multichannel-based learning for audio object extraction
Daniel Arteaga, Jordi Pons
The current paradigm for creating and deploying immersive audio content is based on audio objects, which are composed of an audio track and position metadata. While rendering an ob…
On permutation invariant training for speech source separation
Xiaoyu Liu, Jordi Pons
We study permutation invariant training (PIT), which targets at the permutation ambiguity problem for speaker independent source separation models. We extend two state-of-the-art P…
