# This is the hyperparameter configuration file for Parallel WaveGAN. # Please make sure this is adjusted for the LJSpeech dataset. If you want to # apply to the other dataset, you might need to carefully change some parameters. # This configuration trains more steps up to 1000k compared to v1 config. # It requires 12 GB GPU memory and takes ~7 days on TITAN V. ########################################################### # FEATURE EXTRACTION SETTING # ########################################################### sampling_rate: 22050 # Sampling rate. fft_size: 1024 # FFT size. hop_size: 256 # Hop size. win_length: null # Window length. # If set to null, it will be the same as fft_size. window: "hann" # Window function. num_mels: 80 # Number of mel basis. fmin: 80 # Minimum freq in mel basis calculation. fmax: 7600 # Maximum frequency in mel basis calculation. global_gain_scale: 1.0 # Will be multiplied to all of waveform. trim_silence: true # Whether to trim the start and end of silence. trim_threshold_in_db: 60 # Need to tune carefully if the recording is not good. trim_frame_size: 2048 # Frame size in trimming. trim_hop_size: 512 # Hop size in trimming. format: "hdf5" # Feature file format.
