This is NOT author's implementation.

# gputil # if you need to execute multiple training process
- Download Datasets:
-
Separate each train / test wavs
-
Downsample wavs
# prerequisite : ffmpeg.
# sudo apt-get install ffmpeg (Ubuntu)
bash downsample.sh # all wavs below $PWD will be converted to .flac, 16k samplerate- Train

--ckpt /path/to/saved/checkpoint.pth| PESQ(cRMCn/cRMRn) | Paper | Mine* |
|---|---|---|
| DCUNet - 10 | 2.72/2.51 | 3.03/3.07 |
| DCUNet - 20 | 3.24/2.74 | 3.12/3.11 |
- cRMCn : Complex-valued input/Output
- cRMRn : Real-valued input/Output
Comparing the two(Paper's, Mine) values above is inappropriate for the following reasons:
-
* I did not use matlab code that the author used to calculate pesq, but instead used pypesq.
-
* The Architecture of model is slightly different from the original paper. (Such as kernel size of convolution filters)
-
MelSpec
- Log amplitute estimate has slightly worse performance than non-log amplitude
- Complex-valued network does not make the metric better..
| Mixture | Estimated Speech | GT(Clean Speech) |
|---|---|---|
| mixture1.wav | Estimated1.wav | GroundTruth1.wav |
| mixture2.wav | Estimated2.wav | GroundTruth2.wav |
