LPCNet

Incomplete pytorch implementation of LPCNet

Data preparation

For data preparation use dump_data in github.com/xiph/LPCNet. To turn this into a training dataset, copy data and feature file to a folder and run

python add_dataset_config.py my_dataset_folder

Training

To train a model, create and adjust a setup file, e.g. with

python make_default_setup.py my_setup.yml --path2dataset my_dataset_folder

Then simply run

python train_lpcnet.py my_setup.yml my_output

Inference

Create feature file with dump_data from github.com/xiph/LPCNet. Then run e.g.

python test_lpcnet.py features.f32 my_output/checkpoints/checkpoint_ep_10.pth out.wav

Inference runs on CPU and takes usually between 3 and 20 seconds per generated second of audio, depending on the CPU.
