Pytorch Implementation of SEGAN (Speech Enhancement GAN)

Implementation of SEGAN by Pascual et al. in 2017, using pytorch. Original Tensorflow version can be found here.

Prerequisites

  • python v3.5.2 or higher
  • pytorch v0.4.0
  • CUDA preferred
  • noisy speech dataset downloaded from here
  • libraries specified in requirements.txt

Installing Required Libraries

pip install -r requirements.txt

Data Preprocessing

Use data_preprocess.py file to preprocess downloaded data. Adjust the file paths at the beginning of the file to properly locate the data files, output folder, etc. Uncomment functions in __main__ to perform desired preprocessing stage.

Data preprocessing consists of three main stages:

  1. Downsampling - downsample original audio files (48k) to sampling rate of 16000.
  2. Serialization - Splitting the audio files into 2^14-sample (about 1 second) snippets.
  3. Verification - whether it contains proper number of samples.

Note that the second stage takes a fairly long time - more than an hour.

Training

python model.py

Again, fix and adjust datapaths in model.py according to your needs. Especially, provide accurate path to where serialized data are stored.

Using Tensorboard

In order to use tensorboard, you need to first install tensorboard:

pip install tensorboard

Then run tensorboard by specifing the log directory.

tensorboard --logdir=segan_data_out/tblogs
