Todo

• [X] pitch estimation
• [X] Comb filter
• [X] ERBBand c++ implementation
• [X] Feature(r,g,pitch,corr) Generator(c++) for pytorch
• [X] DNNModel pytorch
• [X] DNNModel c++ implementation
• [ ] Pretrained model
• [X] Postfiltering (done by @TeaPoly )

Requirements

• CMake
• Sox
• Python>=3.6
• Pytorch

Prepare sampledata

1. download and sythesize data DNS-Challenge 2020 Dataset before excute utils/run.sh for training.

git clone -b interspeech2020/master  https://github.com/microsoft/DNS-Challenge.git

2. Follow the Usage instruction in DNS Challenge repo(https://github.com/microsoft/DNS-Challenge) at interspeech2020/master branch. please modify save directories at DNS-Challenge/noisyspeech_synthesizer.cfg sampledata/speech and sampledata/noise each.

Build & Training

This repository is tested on Ubuntu 20.04(WSL2)

1. setup CMake build environments

sudo apt-get install cmake

2. make binary directory & build

mkdir bin && cd bin
cmake ..
make -j
cd ..

3. feature generation for training with sampleData

bin/src/percepNet sampledata/speech/speech.pcm sampledata/noise/noise.pcm 4000 test.output

4. Convert output binary to h5

python3 utils/bin2h5.py test.output training.h5

5. Training run utils/run.sh

cd utils
./run.sh

6. Dump weight from pytorch to c++ header

python3 dump_percepnet.py model.pt

7. Inference

cd bin
cmake ..
make -j1
cd ..
bin/src/percepNet_run test_input.pcm percepnet_output.pcm
