Preprocess Scripts

---

• Note : the order of these scripts is IMPORTANT.
• the preprocessing step is easy. but environment setting is not. please understand.
• If you encounter any problems, please do not hesitate to email me or open an issue to the github.

1. Transcribe piano wavs to midi

• You should transcribe {piano_cover_file.wav} -> {piano_cover_file.mid}

• I recommend you to use original codes from this repo : High-resolution Piano Transcription with Pedals by Regressing Onsets and Offsets Times

• Instead, you can also you my docker script.

  docker run -it --gpus all --rm -v /DIRECTORY_THAT_CONTAINS_PIANO_WAV/:/input -v /DIRECTORY_THAT_MIDI_OUTPUT/:/output jonghochoi/piano_transcribe:bytedance1
  

• If you are using GPU RTX 30XX or higher, this script may not work properly. It's because the version of pytorch is too low(1.4).

• then upgrade the version of pytorch in the docker..

2. Estimate Pop's beats

python bpm_quantize.py DATA_DIR 

3. synchronize midi

python pop_align.py DATA_DIR

4. get separated vocal track

python split_spleeter.py DATA_DIR

5. caculate melody chroma accuracy

python melody_accuracy.py DATA_DIR
