# This is the configuration file for CSMSC dataset. # This configuration is based on HiFiGAN V1, which is an official configuration. # But I found that the optimizer setting does not work well with my implementation. # So I changed optimizer settings as follows: # - AdamW -> Adam # - betas: [0.8, 0.99] -> betas: [0.5, 0.9] # - Scheduler: ExponentialLR -> MultiStepLR # To match the shift size difference, the upsample scales is also modified from the original 256 shift setting. ########################################################### # FEATURE EXTRACTION SETTING # ########################################################### fs: 24000 # Sampling rate. n_fft: 512 # FFT size (samples). n_shift: 128 # Hop size (samples). 12.5ms win_length: 512 # Window length (samples). 50ms # If set to null, it will be the same as fft_size. window: "hann" # Window function. n_mels: 80 # Number of mel basis. fmin: 80 # Minimum freq in mel basis calculation.
