Vocos is a fast neural vocoder that generates audio waveforms from acoustic features in a single forward pass. Unlike typical time-domain GAN vocoders, it generates spectral coefficients which are rapidly converted to audio via inverse Fourier transform. It supports inference from mel-spectrograms and EnCodec quantization tokens, with pretrained models available at 24kHz.
