HiFi++ : a Unified Framework for Neural Vocoding, Bandwidth Extension and Speech Enhancement

This is the unofficial implementation of Vocoder part of HiFi++ : a Unified Framework for Neural Vocoding, Bandwidth Extension and Speech Enhancement.

Training:

python train.py --config config_v2.json

Notes:

• iSTFTNet (https://github.com/rishikksh20/iSTFTNet-pytorch) produces better sounding audios than HiFi++.
