Query: Unconditional Audio Generation with Generative Adversarial Networks and
  Cycle Regularization   In a recent paper, we have presented a generative adversarial network
(GAN)-based model for unconditional generation of the mel-spectrograms of
singing voices. As the generator of the model is designed to take a
variable-length sequence of noise vectors as input, it can generate
mel-spectrograms of variable length. However, our previous listening test shows
that the quality of the generated audio leaves room for improvement. The
present paper extends and expands that previous work in the following aspects.
First, we employ a hierarchical architecture in the generator to induce some
structure in the temporal dimension. Second, we introduce a cycle
regularization mechanism to the generator to avoid mode collapse. Third, we
evaluate the performance of the new model not only for generating singing
voices, but also for generating speech voices. Evaluation result shows that new
model outperforms the prior one both objectively and subjectively. We also
employ the model to unconditionally generate sequences of piano and violin
music and find the result promising. Audio examples, as well as the code for
implementing our model, will be publicly available online upon paper
publication.
