# This is the hyperparameter configuration file for Parallel WaveGAN.
# Please make sure this is adjusted for the CSMSC dataset. If you want to
# apply to the other dataset, you might need to carefully change some parameters.
# This configuration requires 12 GB GPU memory and takes ~3 days on RTX TITAN.
