iSTFTNet : Fast and Lightweight Mel-spectrogram Vocoder Incorporating Inverse Short-time Fourier Transform

This repo try to implement iSTFTNet : Fast and Lightweight Mel-spectrogram Vocoder Incorporating Inverse Short-time Fourier Transform specifically model C8C8I. Disclaimer : This repo is build for testing purpose. The code is not optimized for performance.

Training :

python train.py --config config_v1.json

Note:

• We are able to get good quality of audio with 30 % less training compared to original hifigan.
• This model approx 60 % faster than counterpart hifigan.
