 # This configuration is based on full-band MelGAN but the hop size and sampling
 # rate is different from the paper (16kHz vs 24kHz). The number of iteraions
 # is not shown in the paper so currently we train 1M iterations (not sure enough
-# to converge). The optimizer setting is based on @dathudeptrai advice.
