The minimum length of an audio sample in seconds. Audio shorter than this will be ignored during preprocessing.
The maximum length of an audio sample in seconds. Audio longer than this will be ignored during preprocessing. Increasing the max_audio_length will result in larger memory usage. If you are running out of memory, consider lowering the max_audio_length.
Advanced. The maximum value allowed to be in your wav files. For 16-bit audio, this should be (2**16)/2 - 1.
The sampling rate describes the number of samples per second of audio. The 'input_sampling_rate' is with respect to your vocoder, or spec-to-wav model. This means that the spectrograms predicted by your text-to-spec model will also be calculated from audio at this sampling rate. If you change this value, your audio will automatically be re-sampled during preprocessing.
Advanced. The sampling rate describes the number of samples per second of audio. The 'output_sampling_rate' is with respect to your vocoder, or spec-to-wav model. This means that the wav files generated by your vocoder or spec-to-wav model will be at this sampling rate. If you change this value, you will also need to change the upsample rates in your vocoder. Your audio will automatically be re-sampled during preprocessing.
Advanced. The sampling rate describes the number of samples per second of audio. The 'alignment_sampling_rate' describes the sampling rate used when training an alignment model. If you change this value, your audio will automatically be re-sampled during preprocessing.
Advanced. This is the bit depth of each sample in your audio files.
Advanced. This is the number of bins used by the Fast Fourier Transform (FFT).
Advanced. This is the window size used by the Fast Fourier Transform (FFT).
Advanced. This is the hop size for calculating the Short-Time Fourier Transform (STFT) which calculates a sequence of spectrograms from a single audio file. Another way of putting it is that the hop size is equal to the amount of non-intersecting samples from the audio in each spectrogram.
Advanced. This is the minimum frequency for the lowest frequency bin when calculating the spectrogram.
Advanced. This is the maximum frequency for the highest frequency bin when calculating the spectrogram.
Advanced. This is the number of filters in the Mel-scale spaced filterbank.
Advanced. Defines how to calculate the spectrogram. 'mel' uses the TorchAudio implementation for a Mel spectrogram. 'mel-librosa' uses Librosa's implementation. 'linear' calculates a non-Mel linear spectrogram and 'raw' calculates a complex-valued spectrogram. 'linear' and 'raw' are not currently supported by EveryVoice. We recommend using 'mel-librosa'.
Advanced. The vocoder, or spec-to-wav model is trained by sampling random fixed-size sections of the audio. This value specifies the number of samples in those sections.

A label for the source of data
An attestation that permission has been obtained to use this data. You may not use EveryVoice to build a TTS system with data that you do not have permission to use and there are serious possible consequences for doing so. Finding data online does not constitute permission. The speaker should be aware and consent to their data being used in this way.
The path to the directory with your audio files.
The path to your dataset's filelist.
Advanced. The file-loader function to use to load your dataset's filelist.
Advanced. A list of SoX effects to apply to your audio prior to preprocessing. Run python -c 'import torchaudio; print(torchaudio.sox_effects.effect_names())' to see a list of supported effects.

]The number of samples to include in each batch when training. If you are running out of memory, consider lowering your batch_size.
The number of checkpoints to save.
The interval (in steps) for saving a checkpoint. By default checkpoints are saved every epoch using the 'ckpt_epochs' hyperparameter
The interval (in epochs) for saving a checkpoint. You can also save checkpoints after n steps by using 'ckpt_steps'
How often to check the validation set. Pass a float in the range [0.0, 1.0] to check after a fraction of the training epoch. Pass an int to check after a fixed number of training batches.
Run validation after every n epochs. Defaults to 1, but if you have a small dataset you should change this to be larger to speed up training
Stop training after this many epochs
Stop training after this many steps
Automatically resume training from a checkpoint loaded from this path.

Configuration settings for the optimizer.
The gradient clip value when gan_type='wgan'.
Whether to use a sampler which oversamples from the minority language or speaker class for balanced training.
Whether to read spectrograms from 'preprocessed/synthesized_spec' instead of 'preprocessed/spec'. This is used when finetuning a pretrained spec-to-wav (vocoder) model using the outputs of a trained text-to-spec (feature prediction network) model.
