Description

Hi~ :)
I have trouble in training the PitchDNN model. The README of neural-pitch reveals that "To extract xcorr, add lpcnet_extractor.c and add relevant functions to lpcnet_enc.c, add source for headers/c files and Makefile.am, and compile to generate ./lpcnet_xcorr_extractor object".

But I didn't find the lpcnet_extractor.c in the repository, so where can I find this file? Could you please show me the guidance?

First steps

  1. Read the whole issue, then the project's contributing guide.

  3. Fork the repository and make your change on a branch.
  4. Open a pull request that references the issue number.

Research direction

Start by reading dnn/torch/neural-pitch/README.md and searching the repository for lpcnet_extractor.c, lpcnet_enc.c, and lpcnet_xcorr_extractor. Determine whether the referenced source exists elsewhere or whether the README needs correction; done means the file location or build guidance is clearly documented.
