Synthesizer for Training

Residual Vector Quantizer. Args: dimension (int): Dimension of the codebooks. n_q (int): Number of residual vector quantizers used

BigVGAN is a neural vocoder model that applies anti-aliased periodic activation for residual blocks (resblocks). New in BigVGAN-v2: it can op

Maintain similar input lengths in a batch. Length groups are specified by boundaries. Ex) boundaries = [b1, b2, b3] -> any batch is inclu

Zero-pads model inputs and targets

1) loads audio, speaker_id, text pairs 2) normalizes text and converts them to sequences of integers 3) computes spectrograms from audio

Implements Warmup learning rate schedule until 'warmup_steps', going from 'init_lr' to 'peak_lr' for multiple optimizers.

ConvNeXt Block adapted from https://github.com/facebookresearch/ConvNeXt to 1D audio signal. Args: dim (int): Number of input channels.

Implements 'Scaled Adam', a variant of Adam where we scale each parameter's update proportional to the norm of that parameter; and also lea
