HiFi-GAN: periodic-pattern adversarial vocoding

What changed

Integrated multi-period and multi-scale discrimination with a multi-receptive-field generator to improve efficient mel-conditioned waveform synthesis.

Scientific scope

Integrated multi-period and multi-scale discrimination with a multi-receptive-field generator to improve efficient mel-conditioned waveform synthesis. Inherits GAN vocoders and periodic audio structure. Human-like MOS refers to selected listening tests, not indistinguishability in every context; original hardware throughput is not a general current speed guarantee.

Evidence

The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
