In this repository, i-RevNet-based nonlinear time-frequency transform for speech enhancement is impremented using Pytorch.

Our paper can be found here. If you use codes in this repository, please cite this paper.

In our paper, VoiceBank-DEMAND dataset [2] (available here) is used.

We have tested these codes on follwoing environment:

• Python 3.6.4
• Pytorch 1.4.0
• NumPy 1.17.2
• CUDA Version 10.1
• cuDNN Version 7501

A set of Python codes for training and test are available.

Run "01_train.py" to train a model

Run "02_test.py" to evaluate a model and write .wav files of enhanced speeches
