WebC. Hierarchical VQVAE (HVQVAE) As the sampling rate increases, the model must learn to en-code higher-dimensional input to latent disentangled represen-tations and to synthesize higher-dimensional data to produce a same-length audio, which makes the task increasingly difficult. To overcome this problem, we propose a hierarchical repre- WebHierarchical VQ-VAE. Latent variables are split into L L layers.
