# This is the hyperparameter configuration file for MelGAN.
|
||||
# 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 ~ 8GB memory and will finish within 7 days on Titan V.
|
||||
|
||||
# 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.
