GAN Vocoders

This is a brief introduction of GAN Vocoders, we mainly introduce the losses of different vocoders here.

Model	Generator Loss	Discriminator Loss
Mel GAN	adversial loss Feature Matching	Multi-Scale Discriminator
Parallel Wave GAN	adversial loss Multi-resolution STFT loss	adversial loss
Multi-Band Mel GAN	adversial loss full band Multi-resolution STFT loss sub band Multi-resolution STFT loss	Multi-Scale Discriminator
HiFi GAN	adversial loss Feature Matching Mel-Spectrogram Loss	Multi-Scale Discriminator Multi-Period Discriminator
